Function: getSharedBlackTexture()

getSharedBlackTexture(gl): WebGLTexture

Defined in: rendering/shaders/utils/shared-placeholder-texture.ts:57

Returns a shared, opaque-black, 1x1 texture for gl, creating it on first use. Intended for sampler2D uniforms that must always be bound to something (to avoid a data-dependent fragment shader branch) but should contribute nothing when no real texture is supplied.

Parameters

gl

WebGL2RenderingContext

The WebGL2 rendering context.

Returns

WebGLTexture

The shared black texture.
