WebGL2RenderingContext: vertexAttribDivisor() method

The WebGL2RenderingContext.vertexAttribDivisor() method of the WebGL 2 API modifies the rate at which generic vertex attributes advance when rendering multiple instances of primitives with gl.drawArraysInstanced() and gl.drawElementsInstanced().

Note: When using WebGL 1, the ANGLE_instanced_arrays extension can provide this method, too.

Syntax

js

vertexAttribDivisor(index, divisor)

Parameters

index

A GLuint specifying the index of the generic vertex attributes.

divisor

A GLuint specifying the number of instances that will pass between updates of the generic attribute.

Return value

None (undefined).

Examples

js

gl.vertexAttribDivisor(0, 2);
