Hello everyone,
I have some questions regarding to OSMesa.
I am currently working on a project which I have to use Mesa on an
embedded system.
My current goal is to port the base functions over to the embedded
system, so that I can draw a line on a provided VGA screen.
Since the embedded system I am using does not contain a GPU, therefore
I have decided to use OSMesa for rendering process.
I am wondering if there are any documentations/ specifications for OSMesa?
Anyone know which are the base functions that OSMesa used for the
rendering process?
I have looked into src/mesa/swrast/s_lines.c and s_drawpix.c and
trying to figure out how the code works, am I in the right direction?
Moreover, for example, if I found a drawpix() function, how do I know
if OSMesa actually used this function during rendering process? Is
there any tool/debugger I can use to confirm my findings?
Thank you for your time.
Andy.
See http://cgit.freedesktop.org/mesa/demos/tree/src/osdemos for example
of using OSMesa.
Regards,
Jonathan
