Eric Wasylishen 64d6cbad4f light: remove hack which disable vis culling inside liquids 
instead, implement the equivalent by bridging the PVS across opaque liquid faces
 2023-01-09 01:40:01 -07:00
Eric Wasylishen 6b707b6d5a light: use DecompressAllVis() for getting visdata 2023-01-09 00:43:49 -07:00
Eric Wasylishen 512ad03153 refactor: Mod_Q1BSP_DecompressVis -> DecompressVis 2023-01-08 20:43:53 -07:00
Eric Wasylishen 52fcb7a234 refactor: move Mod_Q1BSP_DecompressVis to bsputils.cc 2023-01-08 20:43:53 -07:00
Eric Wasylishen 2b8f8c826d light: Mod_Q1BSP_DecompressVis: port safety check from DecompressRow 2023-01-08 20:43:53 -07:00
Eric Wasylishen 6697beb607 fix _cone default in q2 maps 2023-01-08 20:01:34 -07:00
Eric Wasylishen 91c678254a light: tweaks to _cone support in q2 2023-01-08 19:57:25 -07:00

Eric Wasylishen a9a11159f4 light: add _surface_minlight_scale light key 
for tweaking minlight given to faces matching surface light templates.

minlight = _surface_minlight_scale * light

lower default from 64 to 1 in q1 mode
 2022-12-30 23:06:28 -07:00
Eric Wasylishen 3d0c756b4f light: fix minlight color on surface lights 
- extra `* 255` was unnecessary, setting_color already does this
- don't use qvec3b as it was causing colors to wrap around the 0..255 range
 2022-12-20 23:44:21 -07:00
Jonathan d5e29a1c90 add _nofill key, which causes an entity to not count as an entity for the purposes of occupancy (for lights in walls, etc)

Eric Wasylishen ff73f13830 light: skip vis culling if lighting channels are used 2022-12-13 23:54:49 -07:00
Eric Wasylishen 00754e588e light: setting an _object_channel_mask implicitly enables shadow casting 2022-12-13 23:37:00 -07:00
Eric Wasylishen ea0ed34506 light: fix light bounds culling breaking channel masking 
the bounds are only calculated for mask 1, so only apply bounds culling for lights on channel 1
 2022-12-13 23:32:14 -07:00
Eric Wasylishen 8aa49699f8 light: rename channel mask keys 
models:
_object_channel_mask

lights:
_light_channel_mask
_shadow_channel_mask
 2022-12-13 23:20:27 -07:00
Eric Wasylishen 181d608c7a light: add missing RTC_SCENE_FLAG_CONTEXT_FILTER_FUNCTION now needed 
also check channelmask/shadowmask in Embree_FilterFuncN
 2022-12-13 20:04:22 -07:00
Eric Wasylishen 92d5c75424 light: experimental light channel mask feature 2022-12-13 19:13:58 -07:00

Eric Wasylishen bded0ab344 light: fix negative lights breaking when bounce in use 2022-12-10 15:10:36 -07:00
Eric Wasylishen 24f79d13bb light: recognize _cone as an alias for spotlight cone angle (q2 compat) 2022-12-09 00:59:49 -07:00
Eric Wasylishen a5b83e088b light: work around visblocking opaque liquids causing light artifacts with -visapprox vis 
in cases when we actually want light to shine through these surfaces
 2022-12-09 00:07:50 -07:00
Eric Wasylishen a70c8f4835 light: fix artifacting with translucent shadows 
Embree is allowed to call the filter function more than necessary.
The previous implementation had side effects that would cause
the translucent shadows to get darker in this case.

As a limitation, we're back to only allowing 1 layer of glass per ray.

Jonathan cde7fd2908 add back in `_bouncestyled` in worldspawn; default to true on Q2 mode 2022-12-06 21:23:05 -05:00

Eric Wasylishen f66e4790a4 qbsp/light: add no_phong texinfo flag (currently not used/exposed) 2022-12-01 01:16:17 -07:00
Eric Wasylishen 1065adecc6 qbsp/light: implement _phong_group key, equivalent to Q2 "value" field 2022-12-01 00:25:05 -07:00
Eric Wasylishen 9fa9124404 light: redesign Q2 phong check 
- always do angle check
- always do gamedef specific exclusions (e.g. warping surfflags don't phong with non-warping)
- if Q2 style phong is requested, but Q1 is not in use, use the default phong angle
- always do smoothing group ID check (preparation for supporting this in Q1 mode via a key)
 2022-11-30 23:24:51 -07:00
Eric Wasylishen 96bdf141bb light: block phong if certain surfflag bits differ between the two faces 
this prevents liquids from phonging with solids
 2022-11-30 22:15:58 -07:00
Eric Wasylishen 5d3fab75b6 light: allow .wal_json metadata to contain "light": [ r, g, b ] to override emissive color 
Use this to fix the "emissive lights" test case so it can run on CI without any texture data
 2022-11-20 23:01:05 -07:00

Merge pull request #337 from TTimo/colorcodes 
Enable support for ANSI color codes on Windows 10 and newer, without …
 2022-11-19 09:10:24 -08:00
Eric Wasylishen 9ab4ea8176 Move SetConsoleMode() call to logging::preinitialize(); helper 
Don't do ENABLE_VIRTUAL_TERMINAL_INPUT as it breaks arrow key history
navigation in Windows Terminal after running one of the ericw-tools exe's.

Eric Wasylishen 4c218f5e91 common: factor out LMSCALE_DEFAULT = 16.0; 2022-11-15 23:52:34 -07:00
ttimo fb459253fe Enable support for ANSI color codes on Windows 10 and newer, without needing to enable system wide. Good for CreateProcess CREATE_NEW_CONSOLE situations. 2022-11-15 11:09:19 -06:00
Eric Wasylishen eb3dfe7952 ltface: use bilinear interpolation in WriteSingleLightmap_FromDecoupled 2022-11-15 00:50:11 -07:00
Eric Wasylishen 46d460277a ltface: support -world_units_per_luxel without -novanilla 
first pass implementation - quality of vanilla LM is bad, due to nearest sampling
the decoupled lightmap
 2022-11-14 23:58:31 -07:00
Eric Wasylishen c6b19fe6da light: implement -novanilla with -world_units_per_luxel 
currently it's required because the non-novanilla path
isn't yet implemented
