ANGLE_instanced_arrays.vertexAttribDivisorANGLE()

The ANGLE_instanced_arrays.vertexAttribDivisorANGLE() method of the WebGL API modifies the rate at which generic vertex attributes advance when rendering multiple instances of primitives with ext.drawArraysInstancedANGLE() and ext.drawElementsInstancedANGLE().

Note: When using WebGL2, this method is available as gl.vertexAttribDivisor() by default.

Syntax

vertexAttribDivisorANGLE(index, divisor)

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.

var ext = gl.getExtension('ANGLE_instanced_arrays');
ext.vertexAttribDivisorANGLE(0, 2);
