THIS COMMIT IS BROKEN AND LEADS TO MISSING TEXTURES
There's a "race" between texture release/acquire on changelevel.
Textures end up being deleted when they shouldn't.
Addressing this is tedious, will be done in the following commits.
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.
They are not used by anything yet.
Fallback to generating regular noise textures if bluenoise ones weren't
found.
Real blue noise textures require Half-Life-PBR repo textures.
Still slightly KORYAVY as:
- there's no cache eviction, it might get full pretty quick
- static-vs-dynamic animation decision is pretty rudimentary, might consider non-animated things as dynamic
- args passing vs global state is meh
Known issues:
- no animations, stuck at first rendered frame of a given submodel.
This is as intended for now, needs BLAS update functionality not yet implemented.
- wrong positions/transforms. Reasons unknown. May be "as intended" too.
- missing heads
- Barney model corruption. Consistent between maps/instances/animation
frames.
Make sure that things get created and destroyed at the right times.
Allow longer-than-map block allocations.
Fix brush model leaks -- previously they weren't destroyed on map
change/game exit properly. Also free geometry ranges accordingly.
Add a note about map loading process, and various models lifetimes.
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.
- explicitly group cache-related fields
- move kusochki allocation to where it's actually used
this makes a step towards better blas management from bottom up
Draft the new accel/blas apis. Consolidate everything accel-related into
vk_ray_accel.c. Start splitting into more atomic functions. Prepare for
blas-model+kusochki split. etc etc.
The new code isn't really used yet.
1. Rename models passed to TLAS to instances.
2. Remove BLAS validation: old, doesn't make sense anymore.
3. Draft general blas mgmt approach in NOTES.md
