Hi, Sam asked me to post the following question on the
mailing list instead:
How would you get hardware acceleration when you
manipulate the frame buffer directly using either
DirectFB, or DGA? Wouldn’t that bypass the 3D
pipelines completely? There is no triangle setup,
T&L,
and etc, how could there by hardware acceleration.
Unless you are talking about 2D. But doesn’t frame
buffer mean the graphics memory (which represents
the
actual screen) that is mmaped to the memory space of
the application? So you are only manipulating the
pixels of the display buffer. What hardware
acceleration can you do?
Thank you,
