WebGLLayerProgram

Defined in: packages/layer-webgl/src/webgl-layer-program/index.ts:25

Base class for fullscreen-quad WebGL layer programs.

Subclasses implement:

• getCustomLayerDefinition() — fragment shader + uniform declarations
• setCameraUniforms() — per-frame camera/view uniforms
• cacheDataUniforms() — data-dependent uniforms (called when the graph changes)

Extends

• Program<string, N, E, G>

Type Parameters

N

N extends Attributes = Attributes

E

E extends Attributes = Attributes

G

G extends Attributes = Attributes
