However 44 there are cases where applications can benefit from adjusting 3D 45 vision parameters directly to experiment with this functionality in 46 applications not yet known to 3D Vision, to assist 3D Vision in 47 setting parameters correctly for unusual situations, or to present 48 application-specific user-accessible controls for 3D Vision 49 parameters. 50 51 This extension provides the ability to explicitly create a surface 52 with 3D Vision support regardless of application detection. 53 54IP Status 55 56 NVIDIA Proprietary 57 58New Procedures and Functions 59 60 None 61 62New Tokens 63 64 Accepted as an attribute to the <attrib_list> parameter of 65 CreateWindowSurface and CreatePbufferSurface 66 67 EGL_AUTO_STEREO_NV 0x3136 68 69Additions to Chapter 3 of the EGL 1.4 Specification (EGL Functions and 70Errors) 71 72 Additions to section 3.5.1 (Creating On-Screen Rendering Surfaces) 73 74 Alter the end of the second to last paragraph: 75 76 Attributes that can be specified in <attrib_list> include 77 EGL_RENDER_BUFFER, EGL_VG_COLORSPACE, EGL_VG_ALPHA_FORMAT, 78 and EGL_AUTO_STEREO_NV. 79 80 Add before the last paragraph of section 3.5.1: 81 82 EGL_AUTO_STEREO_NV specifies whether 3D Vision stereo 83 (stereo override) should be enabled in the driver. The default 84 value of EGL_AUTO_STEREO_NV is zero. 85 86Issues 87 88 None 89 90Revision History 91 92 Rev.
