Once upon a time, there were some BLASes. There were the BLASes for dynamic geometry, that were to be used every frame to draw very dynamic things, like sprites and beams. They were initialized at the very begining of the renderer's lifetime, and were expected to live happily for the entire process duration.
However, an evil NewMap appeared. It didn't care abount anything or anyone, so when it came, it just cleared all the allocators, and allowed other BLASes to be allocated into the same space as dynamic BLASes were already given. This made BLASes live on top of each other, use each others toys and make them fight. They weren't happy.
So we just kill them and creat them again from scratch, when the evil NewMap comes.
The end.
Fixes#729
They don't really belong to neither rt_model_t, nor render model.
Allows having dynamic polylights for func_water entities without "main"
render model, and only water submodels.
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.
1. Completely remove them from geometries
2. Draw skybox where the ray hasn't hit anything
3. In the same fashion sky is not shadowed when there's nothing hit by
the shadow ray.
This allows completely removing the sky material flag.
Also supposedly fixes#474
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.
- 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
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
Known issues:
- apparently BLEND_MIX surfaces should also participate in lighting. Figure out how.
- sensitive to ray tracing order. Need proper OIT (or hacks)
This required uploaded kusochki only later during frame time, just before rendering the model. Otherwise they would get incorrect rendermode.
Also add blend mode debug colors.
They have mismatching frequencies. ModelMetadata should be per-Model, there should be only a few dozen of these.
There maybe hundreds (or even thousands) of materials, but one material can be still referenced by many kusochki.
This only moves fields into new structs, which still belong to Kusok. The real extraction will happen later, see #52.
