3 OPENGL EXTENSIONS

Data transfer is enabled by extensions to OpenGL. The GL_NV_present_video extension

provides a mechanism for the displaying of textures and renderbuffers on the Quadro

SDI output. This extension is supported on both Windows and Linux systems. The

WGL_NV_video_out extension sends pbuffers to the SDI device in the case of Windows

while the

GLX_NV_video_out extension provides the same capabilities on Linux

systems. An application must utilize only one of the extensions as the two extensions

cannot be used together.

In addition to the OpenGL extensions, other useful extensions include the following:

 ARB_occlusion_query

 EXT_timer_query

 EXT_framebuffer_object

 ARB_pixel_format

 ARB_pbuffer

 NV_float_buffer





Note: The WGL_video_out or GLX_video_out OpenGL extensions cannot be

utilized with the GL_present_video OpenGL extension. An application must

choose and utilize a single programming paradigm.

Additional information on these OpenGL extensions can be found in the extension

specifications located at http://developers.nvidia.com or http://www.opengl.org/.
