WebGL2RenderingContext: vertexAttribDivisor() method

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since September 2021.

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.

vertexAttribDivisor(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.

gl.vertexAttribDivisor(0, 2);
