Number

WebGL extension #19

Dependencies

Written against the WebGL API 1.0 specification.

Promoted to core and no longer available as an extension in WebGL API 2.0 specification.

Overview

This extension exposes the ANGLE_instanced_arrays functionality to WebGL.

The following WebGL-specific behavioral changes apply:

Consult the above extension for documentation, issues and new functions and enumerants.

Although the extension contains ANGLE in the name it may be exposed by any implementation, whether or not the implementation uses the ANGLE library.

IDL

[NoInterfaceObject]
interface ANGLE_instanced_arrays {
    const GLenum VERTEX_ATTRIB_ARRAY_DIVISOR_ANGLE = 0x88FE;
    void drawArraysInstancedANGLE(GLenum mode, GLint first, GLsizei count, GLsizei primcount);
    void drawElementsInstancedANGLE(GLenum mode, GLsizei count, GLenum type, GLintptr offset, GLsizei primcount);
    void vertexAttribDivisorANGLE(GLuint index, GLuint divisor); 
};
  

Issues

How does ANGLE_instanced_arrays interact with OES_vertex_array_object?
