28d157af56 Shader builder / add circle and triangle shapes for symbols 2019-09-26 16:30:19 +02:00

9b3a9b5eca Shader builder / add logic for transforming a style into shader params 
This was previously handled by the WebGLPointsLayer class, but is now
externalized and tested.

d5caabbbfc Shader builder / add basic expression parsing 
Only a handful of expressions for now, very loosely based on the
mapbox style spec. Also only work on numerical values.

34572da17b Webgl shader builder / expanded functionality 
Now takes in a custom object with attributes, uniforms etc.
The WebGLPointsLayer uses this to handle image icons.

4de0c0b082 Webgl / add a very simple vertex shader builder utility 
This only allows including hardcoded values in the shader,
and only for symbols.

c48350b666 Webgl buffer / add utility getSize function 
Saves checking whether the buffer was initialized with
an array already

e852294938 Webgl / improve reading of render targets data 
Now two methods are available: `readAll` and `readPixel`,
and the data from the render target is not re-read every time unless
`clearCachedData` is called.

6224d749c4 WebGL / Introduced the WebGLRenderTarget class 
This utility class simplifies rendering to a texture & reading the
results of the render.

It also allows clearing its content before a new render.

f25a16d90c Webgl helper / rework create texture utils 
Now only one util is available: `createTexture`, which
is tested and allows binding an image and reusing an existing texture.

2412fe0211 Webgl / remove handling of element_index_uint extension 
From now on we will assume this extension is always enabled.

An error message have been added in the unlikely scenario of a lack
of support.

33d007ce01 Webgl buffer / now stores data in typed arrays 
The `WebGLBuffer` class API was changed in order to allow populating
the internal array in different ways.

5d2b7fe4bb Webgl points / use the helper ton compute the projection transform 
The `WebGLHelper` class now provides a `makeProjectionTransform` method
that updates a transform to match the projection for a given frame state.

This also means that the WebGLHelper does not set the projection matrix
uniform anymore, this is the responsibility of the renderer as
the rendered coordinates will not be in world space from now on.

3e2e45ce6d Webgl helper / add the possibility to use transforms as custom uniforms 
These will be translated into 4x4 matrices in GLSL.

6b82cf0b84 Simplified the API of WebGLHelper 
Now the shader and program caches are simply arrays of native WebGL created objects.
The WebGLHelper simply takes the sources of the frag and vert shader and produces a program.

This removes 2 classes & reduces the general verbosity of the API.

Also a `getShaderCompilationErrors` was added on `WebGLHelper` to help debug GLSL errors.

ad62739a6e Use blocked scoped variables 
In addition to using const and let, this also upgrades our linter config and removes lint (mostly whitespace).

57db47ac18 Rename ol.structs.Buffer to ol.webgl.Buffer 
The Buffer class is WebGL specific, and it's not really a "data structure", in the pure sense of the term.
