## Coding Guidelines
### Pull Requests
We love pull requests, so be bold with them! Don't be afraid of going ahead
and changing something, or adding a new feature. We're very happy to work with you
to get your changes merged into Trianglify.
If you've got an idea for a change then please discuss it in the open first,
either by opening an issue, or by joining us in our
[MDG public chat room](https://mdg.sdslabs.co/chat).
If you're looking for something to work on, have a look at the open issues in the repository [here](https://github.com/sdsmdg/trianglify/issues).
> We don't have a set format for Pull requests, but we expect you to list changes, bugs generated and other relevant things in PR message.
### MVP architecture
Trianglify is built keeping [MVP (model-view-presenter)](https://en.wikipedia.org/wiki/Model–view–presenter) architecture in mind, so any changes that are proposed to Trianglfiy should follow MVP architecture. If you are confused regarding where a method should be, join us at [MDG public chat room](https://mdg.sdslabs.co/chat), we'll be happy to help.
### Style Check
Trianglify uses Sputnik for performing style checks on the codebase, which helps us in maintaining the quality of the code. Sputnik checks for violation upon submission of Pull Requests. If Sputnik reports a violation and you believe that it is not applicable, just comment `N/A` on the sputnik review with the reason of why it is not applicable. **Pull Requests will only be merged once all the violations are resolved**.
### Git Commit Messages

<p>
### 2.2 Details of Bleed and Grid Dimensions
* **Bleed:** Bleed defines the dimensions of extra size that TrianglifyView view generates so that triangles on the edge don't appear to be chopped off. In most of the cases `min{bleedX, bleedY} > cellSize` would ensure that the view is completely filled.
* **Grid Dimensions:** `GridHeight` and `GridWidth` defines the dimensions of the visible area of the view.
Total area generated by TrianglifyView is (`gridHeight` + 2 * `BleedY`) * (`gridWidth` + 2 * `BleedX`) while total area visible is (`gridHeight`) * (`gridWidth`)
Following image demonstrates region covered by `gridHeight`, `gridWidth`, `bleedX` and `bleedY`
<p>
<img src="resources/default_pattern_explained.jpg" data-canonical-src="resources/default_pattern_explained.jpg" width="350" height="350" />
### 2.4 Note on Units of CellSize, Variance, Bleed and Grid Height
Attributes of `CellSize`, `Variance`, `Bleed` and `GridHeight` supplied to TrianglifyView using Java are interpreted as `px`. To convert px to dp or vice-versa define and use following methods:
```java
public int dpToPx(int dp) {
DisplayMetrics displayMetrics = this.getResources().getDisplayMetrics();
return Math.round(dp * (displayMetrics.xdpi / DisplayMetrics.DENSITY_DEFAULT));
}
public int pxToDp(int px) {
DisplayMetrics displayMetrics = this.getResources().getDisplayMetrics();
return Math.round(px / (displayMetrics.xdpi / DisplayMetrics.DENSITY_DEFAULT));
}
```
### 2.5 Setting Palette using setPalette method
`TrianglifyView`'s `setPalette` method accepts `Palette` object. Palette can be set using one of the following methods:
* To use one of the predefined palette, for example **Spectral** use `trianglifyView.setPalette(Palette.getPalette(Palette.Spectral))`.
* To use palette referring to its index use `Palette.getPalette(<index>)`.
* To use custom palette refer to section [2.6 Using custom Palettes](#26-using-custom-palettes).
> **Note:** Index used for addressing palette should be less than `Palette.DEFAULT_PALETTE_COUNT`, if index is greater than `DEFAULT_PALETTE_COUNT` `IllegalArgumentException` is thrown.
**Note: Palette enum defines total of 28 named palettes that can be used to generate views without specifying colors.**
### 2.6 Using Custom Palettes
Custom Palettes can be used by creating new palette using one of the following constructor:
```java
Palette customPalette = new Palette(int c0, int c1, int c2, int c3, int c4, int c5, int c6, int c7, int c8);
```
or
```java
Palette customPalette = new Palette(int colors[]);
```
> Array based constructor will throw `IllegalArgumentException` if size of array is not exactly 9.
### 2.7 Updating the View
`TrianglifyView` should be updated on change of any of the parameter for changes to take effect. `TrianglifyView` can be updated by the following two methods:
**Smart update of view using `smartUpdate`**
`smartUpdate` updates the view smartly by looking at the parameter changes in the view since the last update, and accordingly decides which parts of the view should be updated. More formal description is:
* If only the `drawStroke` or `fillTriangle` values have been changed since the last update, the triangulation is only replotted in accordance to the new paint strokes.
* If the `randomColoring` or `palette` have been changed without any changes in the grid parameters, only the new colors are assigned to the triangulation without regenerating the grid and delaunay triangulation, after which the view is plotted in accordance to the `fillTriangle` and `drawStrokes` parameters.
* If there are changes in the grid parameters, the whole triangulation has to be generated from scratch. The method generates a new grid according to the parameters and fits a delaunay triangulation. This is followed by colorization and plotting of the triangulation onto the view.
**Complete regeneration using `generateAndInvalidate`**
This is used when the triangulation is to be generated from scratch. The method generates a grid according to the parameters and fits a delaunay triangulation. This is followed by colorization and plotting of the triangulation onto the view.
**(Basic) Performance Comparision of the Two Methods**
`smartUpdate` method regenerates the whole triangulation only when the grid parameters have been changed, thereby bypassing the unnecessary regeneration of grid and delaunay triangulation in situations when parameters other than grid parameters have been changed. This leads to a faster rendering of view.
The `generateAndInvalidate` method regenerates the whole triangulation irrespective of which parameters have been changed, carrying out steps that might not be necessary, hence causing hindrance to performance.
### 2.8 Exporting Bitmap
`TrianglifyView` can export Bitmap object of the triangulation plotted, to get a bitmap object use `getBitmap` method of trianglifyView. `getBitmap` returns a mutable bitmap object that is of `ARGB_8888` configuration.
Quality of the bitmap obtained can be set using `setQuality` method of TrianglifyView which accepts one of the three possible parameter `TrianglifyView.DRAWING_CACHE_QUALITY_HIGH`, `TrianglifyView.DRAWING_CACHE_QUALITY_LOW` and `TrianglifyView.DRAWING_CACHE_QUALITY_AUTO`.
## 3. Performance Analysis
Few notes on performance of Trianglify
* Performance takes a serious hit with decrease in cell size. Time complexity of the algorithm to generate triangles from grid of points is Ω(n*log(n)). Decreasing cell size increases n (number of points on the grid).
* Performance of coloring is faster on the use of random coloring rather than gradient.
* On use of smartUpdate, performance of coloring depends on the parameters changed since last triangulation. Check [2.7 Updating the View](#27-updating-the-view) for more details.

# Credits
Trianglify is inspired from qrohlf's work to generate triangle art, [Trianglify](https://github.com/qrohlf/trianglify)
Development of Trianglify wouldn't have been possible without following libraries:
* [Delaunay Triangulator by jdiemke](https://github.com/jdiemke/delaunay-triangulator)
* [Color Picker by QuadFlask](https://github.com/QuadFlask/colorpicker)
# Guidelines for Contributors
