This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
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.
void gl.vertexAttribDivisor(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.
gl.vertexAttribDivisor(0, 2);
