ImageTexture

Image texture

Helper class storing image as a WebGL texture. Used by shader classes and renderers as wrapper around images providing convenient interfaces.

Constructors

new ImageTexture()

new ImageTexture(gl, size, grayscale, linear): ImageTexture

Constructor

Parameters

• gl: WebGL2RenderingContext
