Hi,
I've noted two bugs in the GL code while running the GL client (try
'make rungl'):
1) The clipping of text vobs is interpolated wrongly: When not
interpolating, everything is fine; when the interpolation starts,
everything is visible; during the interpolation, the visible area
shrinks until in the end the clipping is correct again (i.e., the
clipped area is interpolated from being around the whole text--
rendering everything to be visible-- to being around the padded rect
inside the cell, which is the correct clipping area)
2) The depth buffer stuff doesn't seem to be working; the depth ordering
of overlapping cells is wrong in about 50% of the cases (i.e., seems
unrelated to the actual depth...). To try, you can create the following
structure:
A E--D
| |
B-----C
where A,B,C,D,E are cells; A and E will overlap.
The first issue (interpolation) is extremely nagging (it's the most
glaring problem in the client right now).
