Hello. Everybody: I’ve been reading the source code of mesa recently,
and what puzzles me a lot is that I can’t find the function to fetch pixels
from the color buffer when rendering to the screen. I’ve set several breakpoints in the file “s_span.c(_swrast_read_rgba_span,_swrast_get_values, _swrast_get_row)”
,“wmesa.c(read_rgba_pixels(/spans)_32)”,
which I thought have the most possibility to be the right one, but none of them
was hit when I was running in the debug mode in Visual studio.net 2005. So is there anybody who can give me a clue that which
function may be invoked when the application reads pixels from framebuffer and
render it to the screen. any help will be appreciated. |
