af24afbcc3 rt: draft direct light compute shader 
it's bad:
direct light: 1.8ms, 183(184)v, 59(128)s, LDS=0, 2/16o
(-56 vgpr => +1 wavefront??)

also, thread group size = 16, 8, 1, wave64
while ray tracing pipeline = 8, 4, 1, wave32

b67668430b rtx: fix missing flashlight in c1a4i 
Just increase point lights limit per light cell.

Also:
- update infotool to show point lights info
- move light cluster finalization to vk_scene to make sure infotool has
  the recentmost data

ea1767f2c2 cvar improvements №2 
added vk_only for old -rtx behavior (full disable rtx pipeline)
remove -vkskipdev and skip_first_device as unused and obsolete
remove obsolete check ("missing ray tracing extensions")
addedv VK_LoadCvarsRTX for rtx commands
remove vk_rtx_prev_frame_blend_factor as an outdated command
added vk_deviceid as a stub for video device selection
vk_rtx_reload_materials no longer shown when vk_core.rtx = 0

6e9b54869c rtx: fix shadows for surfaces with alpha mask 2021-12-08 12:08:26 -08:00
Ivan Avdeev
4becafc02c Merge branch 'sample-emissive-lights-textures' into E177 
Also do not multiply emissive textures by emissive color. similar to how
original lighting works.
qrad lighting treats emissive surfaces as constant color w/o paying
attention to texture contents. And then the rederer just draws textures
w/o lightmaps.

We need to figure out what to do with pbr path tracer.

a9d5e4dd22 rtx: draw skybox on SURF_SKY surfaces only 
- change how shadows for environment lights work: should cast light only when hitting SURF_SKY
- add SBT_RECORD_SIZE to specialization; need this for sky/shadow closest hit shader

3f70032e77 Convert fov to radians when computing pixel cone. 
Fixes #167. Textures are still blurry when viewed at an angle as
UVDerivsFromRayCone does not take anisotropy into account.
