1 GETTING STARTED

Application programming of the NVIDIA Quadro

FX SDI is broken into two principle

parts, device control and data transfer. Device control handles the hardware

configuration as well as the starting and stopping of data transfers while data transfer is

the sequence of operations that send graphics data to the video device for output.

The Quadro

FX SDI displays graphics data that has been rendered by the graphics

processing unit (GPU) into one or more OpenGL Frame Buffer Objects (FBO) or

application controlled pbuffers using traditional OpenGL programming techniques. The

resulting standard definition or high definition serial digital video output can be 8, 10, or

12-bit. 10-bit and 12-bit video output must originate from a 16-bit per-component

floating-point render target while 8-bit data can originate from either an 8-bit per-

component integer or a 16-bit per-component floating-point render target. Color data in

an 8-bit FBO or pbuffer should be integer data in the range of 0 to 255, while data placed

by an application into a 16-bit floating point pbuffer or FBO should be 16-bit float data

in the range of 0 to 1.
