WebGL extension #61

Dependencies

Written against the WebGL API 2.0 specification.

Overview

This extension exposes the ANGLE_stencil_texturing functionality to WebGL.

There are no WebGL-specific behavioral changes.

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

IDL

[Exposed=(Window,Worker), LegacyNoInterfaceObject]
interface WEBGL_stencil_texturing {
    const GLenum DEPTH_STENCIL_TEXTURE_MODE_WEBGL = 0x90EA;
    const GLenum STENCIL_INDEX_WEBGL              = 0x1901;
};
  

New Tokens

undefined texParameterf(GLenum target, GLenum pname, GLfloat param)

A new enum DEPTH_STENCIL_TEXTURE_MODE_WEBGL is accepted as the pname parameter; param must be DEPTH_COMPONENT (default) or STENCIL_INDEX_WEBGL.

undefined texParameteri(GLenum target, GLenum pname, GLint param)

A new enum DEPTH_STENCIL_TEXTURE_MODE_WEBGL is accepted as the pname parameter; param must be DEPTH_COMPONENT (default) or STENCIL_INDEX_WEBGL.

any getTexParameter(GLenum target, GLenum pname)

A new enum DEPTH_STENCIL_TEXTURE_MODE_WEBGL is accepted as the pname parameter.

The return type of this method depends on the parameter queried:

pname	returned type
DEPTH_STENCIL_TEXTURE_MODE_WEBGL	GLenum
