It is used by ThingJS for web3d rendering, but can also be used as a standalone library.\n\nt3d'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.\n\n[Examples](https://uinosoft.github.io/t3d.js/examples/) &mdash;\n[Docs](https://uinosoft.github.io/t3d.js/docs/) &mdash;\n[Discord](https://discord.gg/urB54PPXc4)\n\n## Import\n\nUse `t3d.js` or `t3d.min.js` in your page:\n\n````html\n<script src=\"t3d.min.js\"></script>\n````\n\nor import as es6 module:\n\n````javascript\nimport * as t3d from 't3d.module.js';\n````\n\n## Npm\n\nt3d is published on npm. To install, use:\n\n````\nnpm install t3d --save\n````\n\nThis will allow you to import t3d entirely using:\n\n````javascript\nimport * as t3d from 't3d';\n````\n\nor individual classes using:\n\n````javascript\nimport { Scene, Renderer } from 't3d';\n````\n\nSince v0.2.0, the JavaScript files in `examples/jsm` can be imported like this:\n\n````javascript\nimport { OrbitControls } from 't3d/addons/controls/OrbitControls.js';\n````\n\n## CDN\n\n* https://unpkg.com/t3d@latest/build/t3d.min.js\n* https://unpkg.com/t3d@latest/build/t3d.module.js\n\n* https://cdn.jsdelivr.net/npm/t3d@latest/build/t3d.min.js\n* https://cdn.jsdelivr.net/npm/t3d@latest/build/t3d.module.min.js\n\n## Quick Start\n\nCreate a simple rotating cube with PBR materials:\n\n````javascript\n// Initialize renderer with WebGL2\nconst width = window.innerWidth || 2;\nconst height = window.innerHeight || 2;\n\nconst canvas = document.createElement('canvas');\ncanvas.width = width;\ncanvas.height = height;\ndocument.body.appendChild(canvas);\n\n// Create WebGL2 context and renderer\nconst gl = canvas.getContext('webgl2', {\n  antialias: true,\n  alpha: false\n});\nconst renderer = new t3d.WebGLRenderer(gl);\nconst screenRenderTarget = new t3d.ScreenRenderTarget(canvas);\nscreenRenderTarget.setColorClearValue(0.1, 0.1, 0.1, 1);\n\n// Create scene\nconst scene = new t3d.Scene();\n\n// Create mesh with PBR material\nconst geometry = new t3d.BoxGeometry(8, 8, 8);\nconst material = new t3d.PBRMaterial();\nconst mesh = new t3d.Mesh(geometry, material);\nscene.add(mesh);\n\n// Add lighting\nconst ambientLight = new t3d.AmbientLight(0xffffff);\nscene.add(ambientLight);\n\nconst directionalLight = new t3d.DirectionalLight(0xffffff);\ndirectionalLight.position.set(-5, 5, 5);\ndirectionalLight.lookAt(new t3d.Vector3(), new t3d.Vector3(0, 1, 0));\nscene.add(directionalLight);\n\n// Set up camera\nconst camera = new t3d.Camera();\ncamera.position.set(0, 10, 30);\ncamera.lookAt(new t3d.Vector3(0, 0, 0), new t3d.Vector3(0, 1, 0));\ncamera.setPerspective(45 / 180 * Math.PI, width / height, 1, 1000);\nscene.add(camera);\n\n// Animation loop\nfunction loop(count) {\n  requestAnimationFrame(loop);\n\n  // Rotate cube\n  mesh.euler.y = count / 1000 * .5;\n\n  scene.updateMatrix();\n  scene.updateRenderStates(camera);\n  scene.updateRenderQueue(camera);\n\n  renderer.renderScene(scene, camera, screenRenderTarget);\n}\nrequestAnimationFrame(loop);\n````\n\n## Extensions\n\n* [t3d-effect-composer](https://github.com/uinosoft/t3d-effect-composer) - Post Effects extension for t3d.js.\n* [t3d-particle](https://github.com/uinosoft/t3d-particle) - This is a particle system developed based on t3d.js.\n* [t3d-pano](https://github.com/uinosoft/t3d-pano) - Panorama extension for t3d.\n* [t3d-3dtiles](https://github.com/uinosoft/t3d-3dtiles) - A 3dtile extension based on t3d.js.\n* [t3d-dynamic-sky](https://github.com/uinosoft/t3d-dynamic-sky) - Dynamic sky addon for t3d.\n* [t3d-gaussian-splatting](https://github.com/uinosoft/t3d-gaussian-splatting) - A t3d-based implementation of 3D Gaussian Splatting.\n\n## Tools\n\n* [t3d-model-viewer](https://uinosoft.github.io/t3d-model-viewer/) - A Model Viewer based on t3d.js and t3d-effect-composer.\n* [t3d-particle-editor](https://uinosoft.github.io/t3d-particle/editor) - A particle editor based on t3d.js and t3d-particle.\n* [t3d-ibl-baker](https://uinosoft.github.io/t3d-ibl-baker/) - This is a simple tool to bake IBL maps for t3d.\n\n## Contributing\n\nPlease make sure to read the [Contributing Guide](./.github/contributing.md) before making a pull request.\n\n[npm]: https://img.shields.io/npm/v/t3d\n[npm-url]: https://www.npmjs.com/package/t3d\n[npm-size-url]: https://img.shields.io/bundlephobia/minzip/t3d\n[issues-badge]: https://img.shields.io/github/issues/uinosoft/t3d.js.svg\n[issues-badge-url]: https://github.com/uinosoft/t3d.js/issues\n[deepscan]: https://deepscan.io/api/teams/20241/projects/25542/branches/800776/badge/grade.svg\n[deepscan-url]: https://deepscan.io/dashboard#view=project&tid=20241&pid=25542&bid=800776\n[discord]: https://img.shields.io/discord/1069800954494464043\n[discord-url]: https://discord.gg/urB54PPXc4"

There are two skin variations plus a UV template to help out if you want to create your own skin variations.\n\nI'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!!!!!!!\n\nCheck out more of my work at:-\n\nhttp://xu1productions.com/3dstudio/index.html  -  3D Game Resources\n\nhttp://www.psionicdesign.com  -  My Main 2D/3D Digital Art site\n\nPsionic 2002"

    "content": "# GlamVelvetSofa\n\n## Screenshot\n\n![screenshot](screenshot/screenshot_large.jpg)\n\nAbove: screenshot from the [Babylon.js Sandbox](https://sandbox.babylonjs.com/).\n\n## Description\n\nThis 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). \n\nThe 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.\n\nThe model uses several extensions: \n* [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.\n* [KHR_materials_sheen](https://github.com/KhronosGroup/glTF/blob/master/extensions/2.0/Khronos/KHR_materials_sheen) for velvet sheen.\n* [KHR_materials_specular](https://github.com/KhronosGroup/glTF/pull/1719) to colorize facing-angle reflections, which occurs with some fabrics (satins, silks, velvets, etc.).\n* [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.\n* [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.\n\n## Reference Photos\n\nThe 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).\n\nThe 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.\n\nFortunately, 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.\n\n![photo references](screenshot/photoreference_vs_customer.jpg)\n\nPhoto references of the product. Top row: official product photography, bottom row: customer review photography\n\n## KHR_materials_variants\n\nThe 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.\n* Black\n* Champagne\n* Gray\n* Navy\n* Pale Pink\n\n![screenshots of the five variants](screenshot/screenshot_variants.jpg)\n\n## KHR_materials_sheen and KHR_materials_specular\n\nThe 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.\n\n[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. \n\n![screenshots of how the various material layers combine together](screenshot/screenshot_layers.jpg)\n\nTop to bottom: base color alone, sheen color added, specular color added.\n\nA 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. \n\n![the fabric normalTexture](screenshot/normalTexture.jpg)\n\nThe normal map, enlarged and cropped to show detail.\n\n## KHR_lights_punctual\n\nThe 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. \n\nThis 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. \n\nAugmented 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. \n\n![screenshots with punctual enabled and disabled](screenshot/screenshot_punctual.jpg)\n\nTop: Punctual light improves sheen. Bottom: Disabling the punctual light.\n\n## Authoring Details ##\n\nThe 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.\n\n## License Information\n\n(C) 2021, Wayfair LLC.

    "content": "# Normal-Tangent Mirror Test\n\n## Screenshot\n\n![screenshot](screenshot/screenshot-larger.png)\n\n## Description\n\nThis model compares normal maps of various orientations to actual geometry, to test if the model's supplied tangent vectors are being imported and used correctly.  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).\n\nThis 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.\n\n## Top Down\n\n![Top-down View](screenshot/top-down.png)\n\nViewing 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.\n\n## Back Side\n\n![Back-side View](screenshot/back-side.png)\n\nThe 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.\n\n## Problem: Supplied Tangent Vectors Not Used\n\n![Supplied Tangents Ignored](screenshot/supplied-tangents-ignored.png)\n\nThe 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.\n\nThis 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.\n\n## Problem: Flipped Y Axis (or flipped green channel)\n\n![Incorrect flipped Y](screenshot/incorrect-flipped-y.png)\n\nIn 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.\n\nThis 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.\n\n## License Information\n\nCopyright 2017-2018 Analytical Graphics, Inc.\nCC-BY 4.0 https://creativecommons.org/licenses/by/4.0/\nModel and textures by Ed Mackey.\n"

From this angle, the viewer can see the difference between real geometry on the left test cells, and normal-mapped quads on the right.  Normal-mapping works best when viewed face-on.\n\n## Back Side\n\n![Back-side View](screenshot/back-side.png)\n\nThe 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.\n\n## Problem: Flipped Y Axis (or flipped green channel)\n\n![Incorrect flipped Y](screenshot/incorrect-flipped-y.png)\n\nIn 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.\n\nThis 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.\n\n## License Information\n\nCopyright 2017-2018 Analytical Graphics, Inc.\nCC-BY 4.0 https://creativecommons.org/licenses/by/4.0/\nModel and textures by Ed Mackey.\n"

    "content": "# Texture Transform Test\n\n## Screenshot\n\n![screenshot](screenshot/screenshot.jpg)\n\n## Description\n\nThis model demonstrates the usage of the KHR_texture_transform extension. There are six quads in this model using two main textures.\n\nUV  \n<img src=\"glTF/UV.png\" height=\"172\" height=\"172\" />\n\nArrow  \n<img src=\"glTF/Arrow.png\" height=\"86\" height=\"86\" />\n\nNote: Both textures have a gray border and use a sampler that clamps and disables mipmapping.\n\n### Offsets\n\nThe 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.\n\n### Rotation\n\nThe 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.\n\n### Scale\n\nThe 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.\n\n### All\n\nThe 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.\n\n## License Information\n\nDonated by Microsoft for glTF testing\n"
