Replacing ARB shaders
This table should summarize the current state for every ARB shader.
| Filename | Type | Status | Replacement | Testing instructions & Comments |
|---|---|---|---|---|
| heatHazeWithDepth.vfp | Material | OK (2019.05.26) | heatHazeWithDepth.?s | map test/glass
everything behind glass should be warped as you strafe along it |
| heatHazeWithAlphaDepth.vfp | Material | OK (2019.09.15) | heatHazeWithAlphaDepth.?s | Volta 2 Cauldron / setviewpos -880 390 -2700 45 80 15.
The underwater stones are darkened with increasing layers of water on top of them (link). This FM has its own copy of ARB shader. Three more FMs have a copy, but don't use their materials with this shader. |
| heatHaze.vfp | Material | OK (2019.09.14) | heatHaze.?s | Accountant1 / setviewpos -2020 -2570 -125 20 130 0
Rain drops cause waves, which warp the picture of the ground. |
| heatHazeWithMask.vfp | Material | OK (2019.09.14) | heatHazeWithMask.?s | A Night To Remember / setviewpos 4500 -1500 -1210 -90 0 0 (noclip)
When looking up from the bloody water, the ceiling is distorted: that's this shader working. |
| HeatHazeWithMaskAndDepth.vfp | Material | OK (2019.09.15) | HeatHazeWithMaskAndDepth.?s | Used by water_clear material, which is almost everywhere.
For instance, in Accountant1 in sewers at setviewpos -2150 -1720 -445 45 -180 0, water surface distorts floor. |
| heatHazeWithMaskAndBlur.vfp | Material | OK (2019.09.15) | heatHazeWithMaskAndBlur.?s | Currently used only in material water_blurred.
A Night To Remember / setviewpos 6370 -1500 -1350 50 30. Look closer into pot: carrots are not only warped, but also blurred. |
| heatHazeWithMaskAndVertex.vfp | Material | DEAD (2019.09.15) | heatHazeWithMaskAndVertex.?s | Only used in legacy textures/sfx/vpring3 material, which is only used in as a part of caco_lightninghit particle in Requiem FM.
However, the mentioned particle is not referenced in that FM, and is not even loaded. |
| blur.vfp | Material | DEAD (2019.12.01) | blur.?s | Only referenced in textures/fsfx/blur material in tdm_bloom.mtr. The material is not referenced anywhere.
Was added long time ago, not never used (reference). |
| ambientEnvironment.vfp | Material | DEAD (2019.09.14) | ambientEnvironment.?s | Not used anywhere in TDM 2.0+. Was used for new ambient lighting, enabled under tdm_ambient_method 2. Still present in all materials under if (global5==2).
See the original thread and probably disclaimer in wiki article. |
| ambientEnvVertexBlend.vfp | Material | DEAD (2019.09.14) | ambientEnvVertexBlend.?s | A rare special case of ambientEnvironment (link)
Mentioned in St. Alban's Cathedral and NHAT, but seems to be as dead as the ambientEnvironment.vfp. |
| fresnel.vfp | Material | OK (2019.09.14) | fresnel.?s | Accountant1 / setviewpos -2260 -2030 -130 30 -150 0 (better enable lantern)
This puddle is rendered with this shader (no idea about its effect). It seems to be the only usage across all FMs. |
| metaball.vfp | Material/FM | Repacked (2020.02.15) | metaball.?s | In the Black / setviewpos 4800 3350 600 30 -90 0.
You should see on the TV screen: bright yellow spots on blue background; moving, merging, and splitting. If the screen looks uniform without any spots, then it is broken. |
| transparency_hack.vfp | Material | DEAD (2019.11.30) | transparency_hack.?s | Referenced in tdm_translucent.mtr in several versions of translucent/pumpkin.
Not used anywhere. |
| transparent_hack.vfp | Material | DEAD (2019.11.30) | transparent_hack.?s | Used in translucent_exp.mtr in material translucent/wallpaper_fancy_red_experiment.
Works exactly the same as transparency_hack.vfp. Not used anywhere. |
| soft_particle.vfp | Ambient (particles) | OK (2019.09.14) | soft_particle.?s | Set r_useSoftParticles 1 and check e.g. fire.
Start NewJob, go to setviewpos 390 -1440 45 45 22 0 (noclip). Soft particles remove the blocky quadrilateral edges from the piece of wood. |
| environment.vfp | Ambient | OK (2019.05.26) | environment.?s | map test/glass
fake yellow reflections should be visible on the windows |
| bumpyEnvironment.vfp | Ambient | OK (2019.05.27) | bumpyEnvironment.?s | PD2: All the Way Up / setviewpos 4700 -250 -250 / link
Potions should look properly: see t_useGLSL 0, r_uniformTransforms 0 for reference Be sure to check that fake reflection texture is oriented the same way. |
| rotoedge.vfp | Postprocess/Material | OK (2019.09.14) | rotoedge.?s | This is optional/test postprocess shader (reference).
Enabled by g_testPostProcess textures/postprocess/rotoedge on any map. WS3 and WS4 missions have custom version of the material, but don't use it anywhere. It is used in The Creeps FM: run setviewpos -900 480 -350 and take the crown. Everything you see through the revenant should be rotoscoped. |
| cookMath_pass1.vfp
cookMath_pass2.vfp brightPass_opt.vfp blurx.vfp blury.vfp finalScenePass_opt.vfp |
Postprocess | DEAD (2020.02.15) | {name}.?s | As written in bugtracker message, these shaders are no longer used.
The bloom was removed, and color adjustment moved to the new tonemap shader, which also handles gamma/brightness now. |
| afxadd.vfp
afxblend.vfp afxblend2.vfp afxmodulate.vfp afxweight.vfp blurx????.vfp blury????.vfp |
Postprocess | DEAD (2019.11.27) | *.?s | Were used for Bloom before the current postprocessing appeared (reference).
Referenced in tdm_bloom.mtr and tdm_bloom_afx.mtr, but those materials not used anywhere. |
| avgLum.vfp
avgLumInitial.vfp adaptLum.vfp brightPass.vfp simpleHalo.vfp finalScenePass.vfp cookMath_pass3.vfp cookVignette.vfp decodeTexture.vfp |
Postprocess | DEAD (2019.11.27) | *.?s | Were initially used for in postprocessing, but were removed before release (reference).
Referenced in tdm_postprocess.mtr, but those materials not used anywhere. |
| colorProcess.vfp | Postprocess | DEAD (2019.11.30) | colorProcess.?s | Not referenced anywhere except on forums.
It turns the image into grayscale. Not used anywhere. |
| frob.vfp | Material | DEAD (2019.11.30) | frob_arb.?s | Referenced in test_frobhilight.mtr, which is not packaged into releases.
Was implemented in 2009, but was not released (reference) |
| shadow.vp | Ambient | OK | stencilshadow.?s | Run any map, e.g. Closemouthed Shadows. Set r_shadows 1 and check that stencil shadows work properly.
Note: Converted manually, supposedly before 2.06. |
| ambientInteraction.vfp
ambient_cubic_light.vfp |
Interaction | OK | ambientInteraction.?s | Run e.g. Closemouthed Shadows FM and put out the candles. If this shader is not working, then it would be absolutely black in the dark, no matter how bright your monitor is.
Note: converted manually, supposedly before 2.06. |
| ambientLight.vfp | Interaction | DEAD (2020.02.27) | ambientLight.?s | No idea what it was doing... |
| test.vfp
interaction.vfp |
Interaction | OK | interaction.?s | Start any FM, check that basic lighting works.
Note: converted manually, supposedly before 2.06. These two shaders are the most recently updated, so it is quite likely that they were used for simple/enhanced interaction before GLSL arrived. |
| cubic_light_point.vfp
cubic_light_proj.vfp test_cubic_light_point.vfp test_cubic_light_proj.vfp |
Interaction | OK | interaction.?s | Custom version of interaction shader for cubic lights.
For testing, find any cubic light on a map and check that it works... Note: converted manually, supposedly before 2.06. |
| interaction_102.vfp
interaction_direct.vfp test_prev.vfp test_direct.vfp |
Interaction | DEAD | (none) | Most likely, some old versions of interaction shader. |
List of shader Types:
- Material: shader filename is referenced in a stage of stock material definition.
- Currently, each of these shaders exists in both ARB and GLSL version, but ARB version is used only if r_useGLSL is disabled.
- FM: shader supplied or overrided by a particular FM --- most likely, specified in material definition.
- Ambient: shader is loaded directly by C++ code and used during rendering, independent of any light source.
- Interaction: shader is loaded directly by C++ code and used during rendering, in a light-surface interaction.
- Postprocessing: shader used for full-screen effects after main rendering is over.
This post explains different modes for testing.
In order to set OK Status to a shader, please check that it works properly with following settings:
- r_useGLSL 1
- r_forceGlslPrograms 1 (2019.09.14: already removed)
- r_uniformTransforms 0 and 1 (both cases)
Also set the date when you checked it.
Replacement should specify which files contain the equivalent or superseding code in GLSL.
If the replacing code is active only with some settings, write those settings under filename.
Testing instructions must explain how to properly test this shader to ensure that replacement works correctly.
Write exact FM/map, coordinates, settings, what to see/expect, etc.
Some extra:
| Filename | Type | Status | Replacement | Testing instructions & Comments | |
|---|---|---|---|---|---|
| (fixed pipeline) | Designed for use in the 'old stage' routine (draw_common.cpp) but at some point became the 'default' shader for GUI's, etc | OK (2019.05.26) | oldStage.?s | Check any map (e.g. test/glass) + main menu | |
| (extra material stages) | Replacement for material stage frob highlight. | WIP (2019.05.26) | frob.?s | Any map +r_newFrob 1 | |
| (legacy gl texgen's) | Replacement for deprecated texgen code. Material stages TG_SKYBOX_CUBE/TG_WOBBLESKY_CUBE | Stable in 2.07 | cubemap.?s | (insert map name here - Hidden Hands 1?) | |
| (legacy gl texgen's) | Replacement for deprecated texgen code. Light material "fogLight" | Stable in 2.07 | fog.?s | (insert map name here - Heart of Lone Salvation?) | |
| (legacy gl texgen's) | Replacement for deprecated texgen code. Light material "blendLight" | Stable in 2.07 | blend.?s | (insert map name here - Closemouthed Shadows?) | |
| (fixed pipeline) | DepthPass | OK (2019.05.27) | depthAlpha.?s | Check any map (e.g. test/glass).
Used for depth prepass, so if it uses incompatible vertex transform, everything would depth-fight like crazy. |
