Check for NaN/Inf, print exec vectors, print temp registers.
|
|
The 'dots' register wasn't getting properly un-negated and un-swizzled
after emitting the code for back-face lighting. So, if more than one
light source was enabled, the specular exponent for the next light source
was wrong.
During execution we were evaluating pow(x, y) where y was negative instead
of positive. This led to the outcome being zero or NaN.
This fixes the occasional black triangles seen in isosurf when hacked to
enable two-sided lighting.

And print/warn NaN/Inf in print_vertex().

A breakpoint is much nicer than abort when gdb is attached.

Clearly, something else is wrong.

ARGB, not RGBA.

Why didn't this come up before?

We don't upload the pixels with the CPU in that case, so the map will
only serve as a way of triggering cache flushes over a bunch of data we
don't touch.

Make python surface just a dumb (texture, face, level, zslice) tuple.
|
|
Surfaces are now by definition GPU views. So CPU access flags don't make
any sense when creating a surface.
For now we are forcing surfaces to be GPU read/write, but that will go away
soon.
