Custom render features ideas, add more if you have

[0lvin]

Based on: https://github.com/yquake2/ref_vk/issues/40

All features should optional and disabled by default. All models should be implemented inside models.c code without dependencies to render library.

• [ ] tessellation for models
• [ ] Ray tracing
• [x] Md3 model support
• [x] Md5 model support / Re-Release support
• [ ] IQM
• [ ] dynamic lights without light maps, for case if we have light with custom properties,
• [ ] Compressed image formats
• [x] BSPX/DeLMCoupled ReRelease support for lightmap
• [ ] BSP39 support
• [x] QBSP
• [ ] Port dynamic lights from gl3 render,
• [x] support logic to select meshes from model to show,
• [x] generate normals for models with unknown normal pack method, e.g. Dakatana/Anachronox,
• [x] convert surface flags by source game type,
• [ ] 3 bytes compressed normals,
• [x] compress triangles based surfaces to short glcmd as in qwalk,
• [x] Anachronox data package format support
• [x] Dakatana data package format support
• [x] SiN data package format support
• [ ] third person selection from menu,
• [ ] DirectX render,
• [ ] OpenGL 2.0 render
• [ ] direct non compliled map load
• [ ] Quake 3 map load
• [ ] Quake 1 map load
• [x] SiN models load

ReRelease requirements:

• [ ] BSPX support for all sections
• [ ] Support Rerelease demo format read, protocol 2022/2023,
• [ ] Rerelease surface flags for q64 texture flow effects,
• [ ] Rerelease light entities,
• [ ] Utf8 font support
• [ ] translation support
• [ ] All entities and fields support
• [ ] binary search for entities fields and methods,
• [ ] select embedded mods start for Xatrix, Rogue and so on,
• [ ] Rerelease fog effect.
• [ ] surface materials support
• [ ] haptic feedback based on PS 4/Nintendo switch files

I would love to see built-in support for gltf, and especialy loading raw trenchbroom maps. That would make modding and a bunch of possibilities a lot more acessible to users. Basicaly have advanced shaders so the compilation is not required anymore. This include realtime shadow/light and a few other gimmicks.

That would fit nicely along png,wav,zip.

While raytracing "sounds nice" IMO it would be nice to keep a second graphics pipeline which is widely available. So basicaly ensure there is a renderer which works on a variety of target platforms. This will be obviously vulkan as opengl support on OSX ends with 4.3 (or was it 4.1?), so no fancy buffers here or bindless textures ... :(

Especialy thinking about having an engine capable of running on android / ios / console devices too. Targeting a specific high-end graphics api version is totaly unnecessary and custom apis can always be implemented if ever someone comes along and wants to use the engine with state of the art high definition assets and requires those graphics features.

It looks like best way will be create directx render in separate repository and work on merging it to some main repository only after implement functionality level near to gl1/soft render. It could be started as implementation of render for non Rerelease version of repository as it has much more stable in render ABI perspective.

I would love to see built-in support for gltf, and especialy loading raw trenchbroom maps.

Gltf support looks as much bigger task than implement any Quake bsp format and would require implement custom logic in all renders :(

I have not made any investigation and map file format support should be much more simple task and we could compile map file to internal bsp 39 like format on fly.

While raytracing "sounds nice" IMO it would be nice to keep a second graphics pipeline which is widely available.

Noone has really started looking to it as I know, I expect it will be just some flag in Vulkan render

Especialy thinking about having an engine capable of running on android / ios / console devices too.

I suppose that only steam deck could be supported as others has a fully different build pipeline or proprietary libraries :-(

I same time I think everyone will appreciate for any improvements to code quality or porting to a new platform.

I have added support of load bsp's from Heretic 2, Dakatana, Kingpin and Sin. Mostly all of it has with rendering transparent surfaces.

All uses same lump sizes as original Quake 2 except Dakatana and SiN. It's not issue for Dakatana as it has one lump where record is four bytes bigger, but SiN has two lumps with different record size by search sizes that have lump_size mod equal to zero, so I have found only theoretical size of record and fields placings, like texture name and size of text. But it looks like other fields has different placement and sizes so all surfaces looks as non solid :(

Current sin map code in sin branch if someone likes to check.

Add thirdperson options like in KMQuake II

Add thirdperson options like in KMQuake II

Third person option is already implemented https://github.com/yquake2/yquake2remaster/commit/6b4f197ac00fc933e198cef56755d919b68fdb23

[acyc070]

I mean add OPTIONS in menu for thirdperson

I hope this thing will come soon
