Make sure that all SRGB-gamma textures are marked with SRGB format (this
includes all the original textues, 8bit PNG textues). All other
textures (roughness, metallic, normal maps) are linear (UNORM).
Trust KTX2 texture that they store in the correct colorspace.
Then we can just sample textures w/o SRGBtoLINEAR'izing them. Supposedly
this is better because of hw interpolation in the correct colorspace.
This is a bit experimental because Compressonator can't really into
BC7_SRGB, which is sad. And also we need to re-gamma all the textures
for the gamma/srgb-unaware traditional renderer.
Different render sources (model types, render types, etc) might require
different material modes. E.g. brush should be translucent (refractive+mirror)
for blend mix modes. However, smoke particles should not be
mirror/refractive for the same blend mix render type.
This is needed to enable advanced material patching, where the material
can be picked up based on source type, render mode, surface number, etc
etc and all of the above combined if needed.
Previous scheme was picking up materials very late when all of this info
has been already lost.
Renames previous METRICS to COUNTERS. These are still reset to zero
every frame.
Adds new METRICS which are preserved, maintained externally to speeds,
and only sampled by speeds code once per frame.
Also adds new metrics:
- `studio.cached_submodels` -- number of submodels in cache
- `geom.used` -- memory used by long allocations
- `geom.{vertices,indices}` -- counts of vertices/indices for long
allocations
- `geom.dyn_{vertices,indices}` -- counts of vertices/indices for
single-frame dynamic allocations
- Add variable name and registration src:line to the
`r_speeds_list_metrics` output. Makes it easier to reason about where
does this metric come from.
- Group metrics by their modules, makes it easier to discover.
- Do not print the list immediately on command, do it later in the
frame. Makes it print correct latest frame values.
Somehow makes sprites correctly oriented (and winding-culled) for ray
tracing, but makes them disappear (winding-culled) for traditional
renderer. This makes zero sense.
This is a workaround for inconsistent memory management: some subsystems completely clear their memories and start allocating from zero. This leads to overwriting long lived sprite model with garbage.
TODO FIXME
The intent is to manage long-vs-single-frame allocations better.
Previously long allocations were map-long bump allocations, and couldn't be freed
mid-map, as there was neither a reference to the allocated range, nor a
way to actully free it.
Add a two-mode block allocator (similar to previous debuffer alloc) that
allows making long and once allocations. But now long allocations are
backed by "pool" allocator and return references to the range.
This commit doesn't do the deallocation yet, so map chaning doesn't yet
work.
Fixes blending differences in test_brush/test_sprite maps. They now look
fairly similar (modulo color correction).
OIT is still a bit off, but good enough for now
Lerping between sprite frames means drawing two coplanar quads blended the right way. This is not something ray tracing can accommodate easily for all blending modes.
Disable lerping for now
Instead of passing model color around as an implicit global state, pass it per-model.
This makes it (a) easier to track, (b) easy to fix blending issues. E.g. this fixes incorrect coloring of brush and studio models, which is also different.
still not fully there:
- glow is slightly off
- TransAlpha has wrong blending mode
apparently pipeline settings for brushes, models, and sprites are substantially different, need different pipelines
