WebGL2RenderingContext.vertexAttribDivisor

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

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

void gl.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.

Examples

gl.vertexAttribDivisor(0, 2);
