report a issues, request a feature, or ask a question. ## Pull Request Guidelines - Don't send PRs to the `master` branch, send them to the `dev` branch instead. - Make sure your code lints (`npm run lint` ...). - Branch naming convention: use kebab naming, and start with `build|ci|docs|feat|fix|perf|refactor|test`, for example: `refactor-addons-pmrem`. - It's OK to have multiple small commits as you work on the PR - GitHub can automatically squash them before merging. ## Development Setup You will need [Node.js](https://nodejs.org), and NPM (which comes with Node.js) installed on your computer. After cloning the repository, run `npm install` to install all dependencies. ## Scripts - `npm run build` - Build the core library to `build/t3d.js` and `build/t3d.module.js` - `npm run dev` - This will watch the source files and rebuild the library whenever they change - `npm run doc` - This will build the api documentation to `docs/` - `npm run lint` - This will lint the source files using ESLint - `npm run server` - This will start a local server where you can view the examples or docs ## Git Commit Message Convention Currently follows [Angular's commit convention](https://github.com/angular/angular/blob/main/CONTRIBUTING.md#commit). ## Code Formatting Currently, we use eslint to perform code specification and style checks to ensure code uniformity. You can use npm scripts to lint the code, but it is more recommended to use an editor plug-in for automatic code formatting. If you use VSCode, you can install the [ESLint](https://marketplace.visualstudio.com/items?itemName=dbaeumer.vscode-eslint) plug-in and enable the auto-fix option in the settings: ````json { "editor.codeActionsOnSave": { "source.fixAll.eslint": true } } ```` ## Naming Conventions - Variable names use camelCase notation, for example: `camera`, `renderer`. - Class file name, class name uses camel case nomenclature, for example: `OrbitControls.js`, `OrbitControls`. - Use kebab naming for folder names, for example: `kebab`, `kebab-case`. ## Comments We use [JSDoc](https://jsdoc.app/) to generate api documentation, so all the public methods and properties should be documented with JSDoc. ## Project Structure A overview of project structure: ```bash ├─ 📁 .github/ # Github related files │ ├─ 📁 workflows/ # Github ci workflows | ├─ 📄 contributing.md # Contributing guide ├─ 📁 build/ # Build output ├─ 📁 docs/ # Documentation output (not tracked by git) ├─ 📁 examples/ # Examples │ ├─ 📁 jsm/ # Addons for t3d.js, exported to `t3d/addons/` ├─ 📂 node_modules/ # Dependencies (not tracked by git) │ ├─ 📁 rollup # Rollup dependencies │ └─ 📁 ... # Other dependencies (@eslint, @jsdoc, etc.) ├─ 📁 src/ # Source code for core package │ ├─ 📁 ... # The core source files in sub category │ ├─ 📄 main.js # The entry root, export all modules from /src ├─ 📁 tests/ # Tests ├─ 📁 tools/ # Some build tools │ ├─ 📄 doc.config.json # JSDoc config │ ├─ 📄 ... # Other tools ├─ 📄 .editorconfig # Editor config ├─ 📄 .eslintrc.cjs # ESLint config ├─ 📄 .gitignore # Git ignore ├─ 📄 icon.jpg # Icon for t3d.js ├─ 📄 LICENSE # License ├─ 📄 package.json # Package.json for core package ├─ 📄 README.md # Readme └─ 📄 rollup.config.js # Rollup config ``` ## Credits Thank you to all the people who have already contributed to t3d.js! ================================================ FILE: .github/workflows/deploy-to-pages.yml ================================================ name: Deploy examples and docs to Pages on: push: branches: ['dev'] paths-ignore: - 'build/**' workflow_dispatch: permissions: contents: read pages: write id-token: write concurrency: group: 'pages' cancel-in-progress: true jobs: build: name: 'Build job' runs-on: ubuntu-latest steps: - name: Checkout uses: actions/checkout@v4 - name: Setup Node uses: actions/setup-node@v4 with: node-version: 20 cache: 'npm' - name: Install Packages run: npm ci - name: Build Docs run: npm run doc - name: Setup Pages uses: actions/configure-pages@v5 - name: Upload artifact uses: actions/upload-pages-artifact@v3 with: path: '.' deploy: environment: name: github-pages url: ${{ steps.deployment.outputs.page_url }} runs-on: ubuntu-latest needs: build steps: - name: Deploy to GitHub Pages id: deployment uses: actions/deploy-pages@v4 ================================================ FILE: .gitignore ================================================ .DS_Store *.swp # Editor directories and files .vscode/* !.vscode/extensions.json .idea .project *.suo *.ntvs* *.njsproj *.sln *.user .vs/ *.sw? # Logs npm-debug.log /docs **/node_modules *.local .jshintrc ================================================ FILE: .vscode/extensions.json ================================================ { "recommendations": [ "dbaeumer.vscode-eslint" ] } ================================================ FILE: LICENSE ================================================ BSD 3-Clause License Copyright (c) 2021-present, uino Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met: 1.

It is used by ThingJS for web3d rendering, but can also be used as a standalone library. t3d's API borrows the look and feel of three.js—familiar and easy to use—but it is not fully compatible or a drop-in replacement. It keeps a simple, flexible design while adding modern features and extra hooks for real‑time workflows, such as customizable rendering callbacks for finer control and post‑processing, clustered lighting for scalable many‑light scenes, light groups for organizing reusable lights, and other performance-minded optimizations. [Examples](https://uinosoft.github.io/t3d.js/examples/) — [Docs](https://uinosoft.github.io/t3d.js/docs/) — [Discord](https://discord.gg/urB54PPXc4) ## Import Use `t3d.js` or `t3d.min.js` in your page: ````html ```` or import as es6 module: ````javascript import * as t3d from 't3d.module.js'; ```` ## Npm t3d is published on npm. To install, use: ```` npm install t3d --save ```` This will allow you to import t3d entirely using: ````javascript import * as t3d from 't3d'; ```` or individual classes using: ````javascript import { Scene, Renderer } from 't3d'; ```` Since v0.2.0, the JavaScript files in `examples/jsm` can be imported like this: ````javascript import { OrbitControls } from 't3d/addons/controls/OrbitControls.js'; ```` ## CDN * https://unpkg.com/t3d@latest/build/t3d.min.js * https://unpkg.com/t3d@latest/build/t3d.module.js * https://cdn.jsdelivr.net/npm/t3d@latest/build/t3d.min.js * https://cdn.jsdelivr.net/npm/t3d@latest/build/t3d.module.min.js ## Quick Start Create a simple rotating cube with PBR materials: ````javascript // Initialize renderer with WebGL2 const width = window.innerWidth || 2; const height = window.innerHeight || 2; const canvas = document.createElement('canvas'); canvas.width = width; canvas.height = height; document.body.appendChild(canvas); // Create WebGL2 context and renderer const gl = canvas.getContext('webgl2', { antialias: true, alpha: false }); const renderer = new t3d.WebGLRenderer(gl); const screenRenderTarget = new t3d.ScreenRenderTarget(canvas); screenRenderTarget.setColorClearValue(0.1, 0.1, 0.1, 1); // Create scene const scene = new t3d.Scene(); // Create mesh with PBR material const geometry = new t3d.BoxGeometry(8, 8, 8); const material = new t3d.PBRMaterial(); const mesh = new t3d.Mesh(geometry, material); scene.add(mesh); // Add lighting const ambientLight = new t3d.AmbientLight(0xffffff); scene.add(ambientLight); const directionalLight = new t3d.DirectionalLight(0xffffff); directionalLight.position.set(-5, 5, 5); directionalLight.lookAt(new t3d.Vector3(), new t3d.Vector3(0, 1, 0)); scene.add(directionalLight); // Set up camera const camera = new t3d.Camera(); camera.position.set(0, 10, 30); camera.lookAt(new t3d.Vector3(0, 0, 0), new t3d.Vector3(0, 1, 0)); camera.setPerspective(45 / 180 * Math.PI, width / height, 1, 1000); scene.add(camera); // Animation loop function loop(count) { requestAnimationFrame(loop); // Rotate cube mesh.euler.y = count / 1000 * .5; scene.updateMatrix(); scene.updateRenderStates(camera); scene.updateRenderQueue(camera); renderer.renderScene(scene, camera, screenRenderTarget); } requestAnimationFrame(loop); ```` ## Extensions * [t3d-effect-composer](https://github.com/uinosoft/t3d-effect-composer) - Post Effects extension for t3d.js. * [t3d-particle](https://github.com/uinosoft/t3d-particle) - This is a particle system developed based on t3d.js. * [t3d-pano](https://github.com/uinosoft/t3d-pano) - Panorama extension for t3d. * [t3d-3dtiles](https://github.com/uinosoft/t3d-3dtiles) - A 3dtile extension based on t3d.js. * [t3d-dynamic-sky](https://github.com/uinosoft/t3d-dynamic-sky) - Dynamic sky addon for t3d. * [t3d-gaussian-splatting](https://github.com/uinosoft/t3d-gaussian-splatting) - A t3d-based implementation of 3D Gaussian Splatting. ## Tools * [t3d-model-viewer](https://uinosoft.github.io/t3d-model-viewer/) - A Model Viewer based on t3d.js and t3d-effect-composer. * [t3d-particle-editor](https://uinosoft.github.io/t3d-particle/editor) - A particle editor based on t3d.js and t3d-particle. * [t3d-ibl-baker](https://uinosoft.github.io/t3d-ibl-baker/) - This is a simple tool to bake IBL maps for t3d. ## Contributing Please make sure to read the [Contributing Guide](./.github/contributing.md) before making a pull request.

================================================ # Basis Universal GPU Texture Compression Basis Universal is a "[supercompressed](http://gamma.cs.unc.edu/GST/gst.pdf)" GPU texture and texture video compression system that outputs a highly compressed intermediate file format (.basis) that can be quickly transcoded to a wide variety of GPU texture compression formats. [GitHub](https://github.com/BinomialLLC/basis_universal) ## Transcoders Basis Universal texture data may be used in two different file formats: `.basis` and `.ktx2`, where `ktx2` is a standardized wrapper around basis texture data. For further documentation about the Basis compressor and transcoder, refer to the [Basis GitHub repository](https://github.com/BinomialLLC/basis_universal). The folder contains two files required for transcoding `.basis` or `.ktx2` textures: * `basis_transcoder.js` — JavaScript wrapper for the WebAssembly transcoder. * `basis_transcoder.wasm` — WebAssembly transcoder. Both are dependencies of `KTX2Loader`: ```js const ktx2Loader = new KTX2Loader(); ktx2Loader.setTranscoderPath( 'examples/jsm/libs/basis/' ); ktx2Loader.detectSupport( renderer ); ktx2Loader.load( 'diffuse.ktx2', function ( texture ) { const material = new THREE.MeshStandardMaterial( { map: texture } ); }, function () { console.log( 'onProgress' ); }, function ( e ) { console.error( e ); } ); ``` ## License [Apache License 2.0](https://github.com/BinomialLLC/basis_universal/blob/master/LICENSE) ================================================ FILE: examples/libs/basis/basis_transcoder.js ================================================ var BASIS = (() => { var _scriptName = typeof document != 'undefined' ?

It is intended to improve the storage and transmission of 3D graphics. [Website](https://google.github.io/draco/) | [GitHub](https://github.com/google/draco) ## Contents This folder contains three utilities: * `draco_decoder.js` — Emscripten-compiled decoder, compatible with any modern browser. * `draco_decoder.wasm` — WebAssembly decoder, compatible with newer browsers and devices. * `draco_wasm_wrapper.js` — JavaScript wrapper for the WASM decoder. Each file is provided in two variations: * **Default:** Latest stable builds, tracking the project's [master branch](https://github.com/google/draco). * **glTF:** Builds targeted by the [glTF mesh compression extension](https://github.com/KhronosGroup/glTF/tree/master/extensions/2.0/Khronos/KHR_draco_mesh_compression), tracking the [corresponding Draco branch](https://github.com/google/draco/tree/gltf_2.0_draco_extension). Either variation may be used with `DRACOLoader`: ```js const dracoLoader = new DRACOLoader(); dracoLoader.setDecoderPath('path/to/decoders/'); dracoLoader.setDecoderConfig({type: 'js'}); // (Optional) Override detection of WASM support. ``` Further [documentation on GitHub](https://github.com/google/draco/tree/master/javascript/example#static-loading-javascript-decoder). ## License [Apache License

================================================ Jeep designed, modelled and skinned by me, Psionic FREE for use however you like, credits are appreciated!!! It was modelled in Milkshape 3D and includes the MS3D files oriented for X or B3D format (BlitzBasic 3D), its 2032 polys with a 512x512 jpg texture map. There are two skin variations plus a UV template to help out if you want to create your own skin variations. I'd love to see a few screenshots of it being used in-game so feel free to stop by my site and maybe drop by my forums and show us all what your doing with it!!!!!!!

================================================ # GlamVelvetSofa ## Screenshot ![screenshot](screenshot/screenshot_large.jpg) Above: screenshot from the [Babylon.js Sandbox](https://sandbox.babylonjs.com/). ## Description This model represents a real product, a velvet sofa bed being sold [on the Wayfair website](https://www.wayfair.com/furniture/pdp/mercer41-frankie-velvet-86-recessed-arm-sofa-bed-mcrf6337.html). The model is made of three parts, each with their own materials. Two 1024x1024 PNG textures are used for the whole model, an ambient occlusion map and a normal bump map. All UVs are arranged between 0 and 1, and `KHR_texture_transform` is used to repeat the normal map for the fabric. The model uses 4319 triangles and 3204 vertices. The model uses several extensions: * [KHR_lights_punctual](https://github.com/KhronosGroup/glTF/tree/master/extensions/2.0/Khronos/KHR_lights_punctual) to provide a key light for better velvet illumination. Sheen seems to respond better to punctual lights than with image-based lighting alone. * [KHR_materials_sheen](https://github.com/KhronosGroup/glTF/blob/master/extensions/2.0/Khronos/KHR_materials_sheen) for velvet sheen. * [KHR_materials_specular](https://github.com/KhronosGroup/glTF/pull/1719) to colorize facing-angle reflections, which occurs with some fabrics (satins, silks, velvets, etc.). * [KHR_materials_variants](https://github.com/KhronosGroup/glTF/blob/master/extensions/2.0/Khronos/KHR_materials_variants/README.md) to represent the five fabric color options on this product. * [KHR_texture_transform](https://github.com/KhronosGroup/glTF/blob/master/extensions/2.0/Khronos/KHR_texture_transform/README.md) to scale the normal bump texture separately from the ambient occlusion texture. ## Reference Photos The use of real-world photographic reference is meant to help glTF developers with calibrating material features and renderer behavior, so we can more accurately represent e-commerce products. Additional photo reference is available [on the Wayfair website](https://www.wayfair.com/furniture/pdp/mercer41-frankie-velvet-86-recessed-arm-sofa-bed-mcrf6337.html). The official photos of the product have been retouched to emphasize materials and finishes, a common practice in retail photography. This can make the materials difficult to reproduce in a 3D model, as it's tricky to isolate accurate base colors, roughness, specular color, etc. Sometimes a physical sample of the surface is difficult to obtain, and prescribing controlled photography can be onerous for manufacturers. Fortunately, we can rely on customer review photos to provide additional material reference. Although lighting can be poor, customer photos are often unretouched which can offer a less-biased view of the surface materials. The ground truth is usually somewhere in the middle, since the official photography provides higher resolution and controlled lighting, while the customer imagery provides little or no retouching. ![photo references](screenshot/photoreference_vs_customer.jpg) Photo references of the product. Top row: official product photography, bottom row: customer review photography ## KHR_materials_variants The model uses the extension [KHR_materials_variants](https://github.com/KhronosGroup/glTF/blob/master/extensions/2.0/Khronos/KHR_materials_variants/README.md) to add five fabric variants. Each uses slightly different UV offsets via `KHR_texture_transform` to add variety. * Black * Champagne * Gray * Navy * Pale Pink ![screenshots of the five variants](screenshot/screenshot_variants.jpg) ## KHR_materials_sheen and KHR_materials_specular The extension [KHR_materials_sheen](https://github.com/KhronosGroup/glTF/blob/master/extensions/2.0/Khronos/KHR_materials_sheen) is used for the main fabric color; it best represents how velvet microfibers interact with lighting at glancing angles. [KHR_materials_specular](https://github.com/KhronosGroup/glTF/pull/1719) is used to colorize reflections on dielectric (non-metal) surfaces. Velvet, satin, silk, and similar fabrics can colorize reflections which makes them difficult to replicate in a traditional PBR metal-rough material. ![screenshots of how the various material layers combine together](screenshot/screenshot_layers.jpg) Top to bottom: base color alone, sheen color added, specular color added. A normalTexture simulates the bending of velvet microfibers from human touches, by bending the surface normals to point at different areas of the image-based lighting. The texture is a combination of tiled "grunge" patterns. The red channel was rotated 90 degrees to create variation, the blue channel was filled with white, and a cotton-weave normal map was overlaid. Then the texture was re-normalized. ![the fabric normalTexture](screenshot/normalTexture.jpg) The normal map, enlarged and cropped to show detail. ## KHR_lights_punctual The extension [KHR_lights_punctual](https://github.com/KhronosGroup/glTF/tree/master/extensions/2.0/Khronos/KHR_lights_punctual) is used to add a directional light to the model, with its Intensity set to 3. This provides better velvet illumination, as sheen responds better to punctual lights than to image-based lighting (IBL) alone. This is highly dependent on the exposure range in each IBL, however most IBLs do not capture strong exposure values for the lights unless the sun or a suitably bright light source are present. In these examples, the "studio" IBL from Babylon.js was used, which uses +2.40 stops for each light. Augmented reality IBLs typically contain a low value range, as they're often created by transforming the view from the mobile device's front camera. It is hoped the addition of a punctual light can restore the benefits of strong key light to improve the sheen response. ![screenshots with punctual enabled and disabled](screenshot/screenshot_punctual.jpg) Top: Punctual light improves sheen. Bottom: Disabling the punctual light. ## Authoring Details ## The model was created with [3ds Max](https://www.autodesk.com/products/3ds-max/) and exported to glTF via the [Max2Babylon](https://github.com/BabylonJS/Exporters/tree/master/3ds%20Max) exporter. The glTF file was then edited manually in [Visual Studio Code](https://code.visualstudio.com) with the [glTF Tools](https://github.com/AnalyticalGraphicsInc/gltf-vscode) extension to add KHR extensions and fine-tune material values. ## License Information (C) 2021, Wayfair LLC.

Note that this model (`NormalTangentMirrorTest`) supplies tangent vectors, and specifically tests a rendering engine's ability to use the supplied vectors as opposed to generating them automatically. To test automatic generation of tangent vectors, see [`NormalTangentTest`](../NormalTangentTest/README.md). This test is best performed with an environment map that contains a clear horizon line, so it is easy to spot if the reflection of the horizon is level. The screenshot above shows a successful render of this model from the front. All of the test blocks show similar reflections. ## Top Down ![Top-down View](screenshot/top-down.png) Viewing off-axis, such as top-down in this case, breaks the illusion provided by normal-mapping. From this angle, the viewer can see the difference between real geometry on the left test cells, and normal-mapped quads on the rest. Normal-mapping works best when viewed face-on. ## Back Side ![Back-side View](screenshot/back-side.png) The back of the model shows concave geometry and normal maps, like looking into a set of mirror-bowls. It is expected to see the sky below the ground in the reflections. Above is a correct rendering of the back. ## Problem: Supplied Tangent Vectors Not Used ![Supplied Tangents Ignored](screenshot/supplied-tangents-ignored.png) The above image was taken in a different rendering engine with a different environment map, but the results should still be clear. A red border has been added for emphasis on the incorrect results. Here, the horizon line appears level in all the test blocks, but the two "Mirror" sets of tests show inverted reflections, as if seen from the back instead of the front. This problem is typically caused by a rendering engine that ignores the supplied tangent vectors and calculates its own. Without the supplied tangent vectors, the engine does not know that the geometry has been mirrored from the original normal-mapped column, and it calculates an inverted set of axes for the reflection vectors. ## Problem: Flipped Y Axis (or flipped green channel) ![Incorrect flipped Y](screenshot/incorrect-flipped-y.png) In the above image, note the test cells on the right three blocks of each set. A red border has been added for emphasis on the incorrect results. Here, the real geometry reflects level horizon lines, but the normal-mapped geometry appears to reflect several different orientations. This is a common problem, that often indicates the rendering engine has mis-interpreted the direction of the normal Y vector, supplied by the green channel of the normal map. Some systems intentionally use or expect left-handed normal maps, however, glTF [specifies](https://github.com/KhronosGroup/glTF/tree/065a01206014cd5f198085de6b4ce6f565ae79c6/specification/2.0#materialnormaltexture) that its own normal maps should use the OpenGL convention with right-handed coordinates. This issue can often be fixed by flipping the normal Y vector, or inverting the intensity of the green channel of the normal map. Fixes should be applied such that glTF models contain only the specified OpenGL normal convention, and rendering engines automatically adapt this to their own internal convention as needed. ## License Information Copyright 2017-2018 Analytical Graphics, Inc.

Above is a correct rendering of the back. ## Problem: Flipped Y Axis (or flipped green channel) ![Incorrect flipped Y](screenshot/incorrect-flipped-y.png) In the above image, note the test cells on the right half of each pair. A red border has been added for emphasis on the incorrect results. Here, the real geometry reflects level horizon lines, but the normal-mapped geometry appears to reflect several different orientations. This is a common problem, that often indicates the rendering engine has mis-interpreted the direction of the normal Y vector, supplied by the green channel of the normal map. Some systems intentionally use or expect left-handed normal maps, however, glTF [specifies](https://github.com/KhronosGroup/glTF/tree/065a01206014cd5f198085de6b4ce6f565ae79c6/specification/2.0#materialnormaltexture) that its own normal maps should use the OpenGL convention with right-handed coordinates. This issue can often be fixed by flipping the normal Y vector, or inverting the intensity of the green channel of the normal map. Fixes should be applied such that glTF models contain only the specified OpenGL normal convention, and rendering engines automatically adapt this to their own internal convention as needed. ## License Information Copyright 2017-2018 Analytical Graphics, Inc.

FILE: examples/resources/models/gltf/TextureTransformTest/README.md ================================================ # Texture Transform Test ## Screenshot ![screenshot](screenshot/screenshot.jpg) ## Description This model demonstrates the usage of the KHR_texture_transform extension. There are six quads in this model using two main textures. UV Arrow Note: Both textures have a gray border and use a sampler that clamps and disables mipmapping. ### Offsets The top row tests different combinations of the offset parameter with UV coordinates of `(0.0, 0.0)` to `(0.5, 0.5)` and offsets of `(0.5, 0.0)`, `(0.0, 0.5)`, and `(0.5, 0.5)` respectively from left to right, using the UV texture. A yellow image indicates that offset was not applied. ### Rotation The bottom left quad tests the rotation parameter with UV coordinates of `(0.0, 0.0)` to `(1.0, 1.0)` and a rotation angle of `‪0.392699‬` radians or `22.5` degrees, using the arrow texture. The green marker indicates the correct rotation. The yellow marker indicates the rotation was not applied. The red marker indicates the rotation was applied in the opposite direction. ### Scale The bottom middle quad tests the scale parameter with UV coordinates of `(0.0, 0.0)` to `(1.0, 1.0)` and a scale of `1.5`, using the arrow texture. The green marker indicates the correct scale. The yellow marker indicates the scale was not applied. ### All The bottom right quad tests offset, rotation, and scale at the same time. If everything is supported correctly, the arrow should point to the green marker. ## License Information Donated by Microsoft for glTF testing ================================================ FILE:
