Creator3D programming

[raymond.meyer%rambler.ru@localhost]

I'm trying to program Sun Creator3D framebuffer, by mmapping /dev/fb0
and then writing to various framebuffer registers/memory regions. So
far I haven't had much success. I've been trying to use DFB24 Access
Mode, which should be the simplest method for modifying pixel data, as
it bypasses rendering pipeline.

Can anyone give me a few examples of how to modify pixels on the
screen? How does Xorg sunffb use the hardware, does it use
framebuffer rendering pipeline? Say for example, I want to set pixel at
location (10, 10) to black colour, can I use either direct (i.e. bypass
rendering pipeline) or accelerated path? How can I do it?
