More progress, NEWCLIP added to doomdef.h, sadly it actually all lags the game so I've disabled it for now Other notes: * on second thought I'll keep the hw_clip functions' gld prefixes rather than HWR, not like it matters either way * despite the extra lag it does fix the issues with translucent walls and such when displayed at different vertical angles, such as with the GFZ1 waterfall

Better fog block colouring They still aren't perfect, but now they are at least not quite so obviously just translucent polygons over the level. A mixture between partially modulating the background colours and adding the fog colour. Notably white fog blocks look like they're brightening what's behind them. Additive was also setting noalphatest before, can probably decide that depending on what it needs anyway. I don't think it's currently used anyway.

More progress, NEWCLIP added to doomdef.h, sadly it actually all lags the game so I've disabled it for now Other notes: * on second thought I'll keep the hw_clip functions' gld prefixes rather than HWR, not like it matters either way * despite the extra lag it does fix the issues with translucent walls and such when displayed at different vertical angles, such as with the GFZ1 waterfall

Some fixes and updates for HWR_SplitWall Solid walls *can* be cut Fix issues with water and fog FOFs not cutting each other out correctly Fix Fog colourmap and lighting setting that is done here. Remove HWR_SplitFog There is currently a bug with FF_DOUBLESHADOW (that also exists in software) but has a larger impact here. When 2 FF_DOUBLESHADOW lights are directly stacked on each other the bottom one has its height set incorrectly. This causes all the Fog in the timed gravity flipping section of ERZ2 to be drawn and it looks really bad.

More progress, NEWCLIP added to doomdef.h, sadly it actually all lags the game so I've disabled it for now Other notes: * on second thought I'll keep the hw_clip functions' gld prefixes rather than HWR, not like it matters either way * despite the extra lag it does fix the issues with translucent walls and such when displayed at different vertical angles, such as with the GFZ1 waterfall

Remove HWR_SplitFog There is currently a bug with FF_DOUBLESHADOW (that also exists in software) but has a larger impact here. When 2 FF_DOUBLESHADOW lights are directly stacked on each other the bottom one has its height set incorrectly. This causes all the Fog in the timed gravity flipping section of ERZ2 to be drawn and it looks really bad.

Various Transparent Texture Fixes Draw Textures and Flats that have holes in them like a solid polygon so they use the depth buffer and don't need to be sorted Disable all linear filtering on textures and flats that have holes in them, the linear filtering introduces translucency into the textures where the edges are. Leaving them with either a black border, or causing pixels behind the slightly translucent areas to not be drawn. Doesn't apply to sprites and the HUD as they are always already sorted properly. Make the Alpha Testing more strict on non-translucent blend modes. This makes it so any transparency below 0.5 is discarded instead. Would make anything that is blended and has holes in it look slightly better, only the HUD and MD2s where the texture has holes are effected currently. Set TF_TRANSPARENT on flat texture flags when there are holes in the texture. Minor fix to make sure MD2s always set the right blend mode

Various Transparent Texture Fixes Draw Textures and Flats that have holes in them like a solid polygon so they use the depth buffer and don't need to be sorted Disable all linear filtering on textures and flats that have holes in them, the linear filtering introduces translucency into the textures where the edges are. Leaving them with either a black border, or causing pixels behind the slightly translucent areas to not be drawn. Doesn't apply to sprites and the HUD as they are always already sorted properly. Make the Alpha Testing more strict on non-translucent blend modes. This makes it so any transparency below 0.5 is discarded instead. Would make anything that is blended and has holes in it look slightly better, only the HUD and MD2s where the texture has holes are effected currently. Set TF_TRANSPARENT on flat texture flags when there are holes in the texture. Minor fix to make sure MD2s always set the right blend mode

Pushing all my work to make OpenGL consistent with my changes to software's sky so far

// properly render skies (consider door "open" if both ceilings are sky)
Added proper support for upside-down thok barriers, in both renderers Thankfully it was really just a copy+paste of the code I already tinkered with for the normal ceiling sky based thok barriers, but tweaked for floors instead
2018-02-03 19:48:18 +00:00
// same for floors
Fixed sky-sky thok barriers showing HOM (turns out the floor and ceiling share the same plane, so I've modified the code to account for this) Additionally, place some optimisations in both software and OpenGL; in particular one has been added for when all of back and front sector (floor and ceiling) is sky: since everything is "open" anyway, we can simply the usual checks involved.

Better fog block colouring They still aren't perfect, but now they are at least not quite so obviously just translucent polygons over the level. A mixture between partially modulating the background colours and adding the fog colour. Notably white fog blocks look like they're brightening what's behind them.

Various Transparent Texture Fixes Draw Textures and Flats that have holes in them like a solid polygon so they use the depth buffer and don't need to be sorted Disable all linear filtering on textures and flats that have holes in them, the linear filtering introduces translucency into the textures where the edges are. Leaving them with either a black border, or causing pixels behind the slightly translucent areas to not be drawn. Doesn't apply to sprites and the HUD as they are always already sorted properly. Make the Alpha Testing more strict on non-translucent blend modes. This makes it so any transparency below 0.5 is discarded instead. Would make anything that is blended and has holes in it look slightly better, only the HUD and MD2s where the texture has holes are effected currently. Set TF_TRANSPARENT on flat texture flags when there are holes in the texture. Minor fix to make sure MD2s always set the right blend mode

Decrease far clipping plane The Far clipping plane did not need to be nearly as high as it was, the new value is 32768, which I suspect is about how far software can render before it completely falls apart. It is desirable to increase the near clipping plane to between 6-10, but it can introduce more issues with close geometry not being drawn when the player or camera is scaled or viewheight is set to MIN in first person view. It would also stop sprites from being drawn ever so slightly too early, but this isn't too much of an issue and isn't too noticeable with those values. Might look into scaling near clipping plane in accordance to camera scale in the future. The reason for wanting to increase the near clipping plane is because the small value can cause very noticeable Z-fighting where there shouldn't be on older GPU's, usually Intel ones, that don't support 24-bits for the depth buffer.

Optimise the screen texture setup for SDL2, Post-processor, and wipes. Only use glCopyTexImage2D when first creating the screen texture, use glCopyTexSubImage2D anytime after that as it does not define a new texture each time. Flushing of the screen textures has been implemented for when the screen size changes (so that the screen textures don't stay at a wrong size) and the game is closed, I believe they would leave a memory leak before.

Optimise the screen texture setup for SDL2, Post-processor, and wipes. Only use glCopyTexImage2D when first creating the screen texture, use glCopyTexSubImage2D anytime after that as it does not define a new texture each time. Flushing of the screen textures has been implemented for when the screen size changes (so that the screen textures don't stay at a wrong size) and the game is closed, I believe they would leave a memory leak before.
