The bright end of the color map is actually twice the palette value, but
I didn't understand this when I came up with the shirt/pants color
scheme for vulkan. However, the skin texture can store only 0..1, so the
mapping to 0..2 needs to be done in the shader. It looks like it works
at least better: the gold key at the end of demo1 doesn't look as bleh,
though I do get some weird colors still on ogres etc.
I was wondering why scaled-down quake-guy was dimmer than full-size
quake-guy. And the per-fragment normalization gives the illusion of
smoothness if you don't look at his legs (and even then...).
This gets the alias pipeline in line with the bsp pipeline, and thus
everything is about as functional as it was before the rework (minus
dealing with large texture sets).
Smashing everything in the process :P (need to work on the C side).
However, while bindless is supposedly good for performance, the biggest
gain this will bring is portability: the texture counts are
automatically limited to what the hardware can handle, and the reliance
on push descriptors is removed (though they were nice and did help get
things up and running).
That was... easier than expected. A little more tedious that I would
have liked, but my scripting system isn't perfect (I suspect it's best
suited as the output of a code generator), and the C side could do with
a little more automation.
While I could reconstruct the position from the screen coords and depth,
this is easier and good enough for now. Reconstruction is an
optimization thing.
