Such companies don't release the programming interface for their
products. That's why they provide custom, often binary only, drivers,
built in-house.

You can however either use the VESA interface, (which won't get the
maximum out of the card), or use OpenGL and/or DierctX APIs. They in
turn will do the needfull, provided of course, you've installed the
GPU's drivers for your OS.

Hi Santosh
I am a os developer and i am currently developing my GUI library,
i found if i use CPU to draw something to the screen, it is very very
slow, the refresh rate will become <2 per second, which is
unacceptable.
If the display card company really don't release the interface,
using vesa is the only one way to help me? May be i can compile some
linux graphic libraries to static library and link to my os.
