Number

    EGL Extension #46

Dependencies

    Requires EGL 1.4

    Written against the EGL 1.4 specification.

Overview

    NVIDIA 3D Vision provides stereoscopic 3d rendering without
    requiring applications to change their rendering methods. However
    there are cases where applications can benefit from adjusting 3D
    vision parameters directly to experiment with this functionality in
    applications not yet known to 3D Vision, to assist 3D Vision in
    setting parameters correctly for unusual situations, or to present
    application-specific user-accessible controls for 3D Vision
    parameters.

    This extension provides the ability to explicitly create a surface
    with 3D Vision support regardless of application detection.

New Procedures and Functions

    None

New Tokens

    Accepted as an attribute to the <attrib_list> parameter of
    CreateWindowSurface and CreatePbufferSurface

        EGL_AUTO_STEREO_NV                0x3136

Additions to Chapter 3 of the EGL 1.4 Specification (EGL Functions and
Errors)

    Additions to section 3.5.1 (Creating On-Screen Rendering Surfaces)

    Alter the end of the second to last paragraph:

        Attributes that can be specified in <attrib_list> include
        EGL_RENDER_BUFFER, EGL_VG_COLORSPACE, EGL_VG_ALPHA_FORMAT,
        and EGL_AUTO_STEREO_NV.

    Add before the last paragraph of section 3.5.1:
        
        EGL_AUTO_STEREO_NV specifies whether 3D Vision stereo
        (stereo override) should be enabled in the driver. The default
        value of EGL_AUTO_STEREO_NV is zero.

Issues
