Class: abstract WebGLLayerProgram<N, E, G>

This program is based on the base Program from Sigma, but instead of using this.array to iterate over the vertices, it is bound to some uniform directly for the fragment shader.

So, when extending this new CustomLayerProgram abstract class:

• Do not implement getDefinition, implement getCustomLayerDefinition instead
• Do not implement setUniforms, implement setCameraUniforms and cacheDataUniforms instead

Extends

• Program<string, N, E, G>

Type Parameters

• N extends Attributes = Attributes

• E extends Attributes = Attributes

• G extends Attributes = Attributes

Constructors

new WebGLLayerProgram()

new WebGLLayerProgram<N, E, G>(gl, pickingBuffer, renderer): WebGLLayerProgram<N, E, G>

Parameters

• gl: WebGLRenderingContext | WebGL2RenderingContext

• pickingBuffer: null | WebGLFramebuffer

• renderer: Sigma<N, E, G>

Returns

WebGLLayerProgram<N, E, G>
