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.
void ext.vertexAttribDivisorANGLE(index, divisor);
indexGLuint specifying the index of the generic vertex attributes.divisorGLuint specifying the number of instances that will pass between updates of the generic attribute.None.
var ext = gl.getExtension('ANGLE_instanced_arrays');
ext.vertexAttribDivisorANGLE(0, 2);
