* moved the sprite renaming out of the file system entirely into a caller-provided callback.
* renamed several functions to closer match the terms of a file system.
* moved the VM interface out of the implementation.
This had two different flags that were checked totally inconsistently, and one was not even saved.
Moved everything into a few subfunctions so that these checks do not have to be scattered all over the code.
This will mostly ensure that each patch used for composition is only loaded once and automatically unloaded once no longer needed.
So far only for paletted rendering, but the same logic can be used for true color as well.
In ZDoom this would affect everything using a patch that got used in a front sky layer, even if the texture was totally unrelated. It is only owed to the low usability of such patches for other purposes that this hasn't caused problems.
Previously it tried to copy all patches of composite sub-images directly onto the main image.
This caused massive complications throughout the entire true color texture code and made any attempt of caching the source data for composition next to impossible because the entire composition process operated on the raw data read from the texture and not some cacheable image. While this may cause more pixel data to be processed, this will be easily offset by being able to reuse patches for multiple textures, once a caching system is in place, which even for the IWADs happens quite frequently.
Removing the now unneeded arguments from the implementation also makes things a lot easier to handle.
* it's no longer the main texture objects managing the pixel buffer but FSoftwareTexture.
* create proper spans for true color textures. The paletted spans only match if the image does not have any translucent pixels.
* create proper warp textures instead of working off the paletted variants.
As a side effect, caching of pixel buffers for texture composition is temporarily disabled, as it management of texture redirections. These things will be reimplemented once things progress further. The existing methods here had their share of serious issues that should be fixed.
This was done to make reviewing easier, again because it is virtually impossible to search for the operators in the code.
Going through this revealed quite a few places where texture animations were on but shouldn't and even more places that did not check PASLVERS, although they were preparing some paletted rendering.
Setting the buffer and its attribute bindings must be one step, not twp. With Vulkan this is a single API call.
This removes the now obsolete SetVertexBuffer method from the model renderer's interface.
Add smoothGroup member to OBJFace struct, and assign the current smooth group number to it
Move face normal calculation code to CalculateNormalFlat
Add AddVertFaces method, which initializes and populates the vertFaces array of arrays, which holds references to triangle references per vertex
Only initialize and populate vertFaces if the model has missing normals and smooth groups
Assign smooth groups to triangle data
Add CalculateNormalSmooth method, which calculates the normals for each face the vertex is attached to, depending on whether or not the faces are part of the given smooth group, and averages them out
Add OBJTriRef struct, which holds references to triangles on OBJ surfaces
Make {agg,cur}SurfFaceCount unsigned ints
Change nvec to a value instead of a pointer
(This clearly shows that using 'long' as parameters in any interface must be stopped. It is fundamentally unsafe to have a type whose size is not reliable - it's either an int-sized nor a pointer sized value, depending on the platform, and essentially worthless.)
Pass surf->vbStart to SetupFrame instead of 0, and pass 0 to DrawArrays instead of surf->vbStart.
Use a potentially faster method of modifying the OBJ file text buffer by modifying it directly.
Add RealignVector and FixUV methods to begin work on re-aligning OBJ models to the same orientation as MD3 models.
Re-align OBJ models to match MD3 models
Fix normal calculation for re-aligned OBJs
Ensure AddSkins does not go out of bounds of surfaceskinIDs
Do not precache skins that were replaced by the user.
Fix OBJs with a large number of materials not being fully rendered
Print a warning message if a material referenced by the OBJ could not be found.
Free surface triangles once they are no longer needed
Also, use continue instead of return so that surfaces after those with missing materials are still rendered.
Fail if a face side has no vertex reference. Vertex references are required for a valid OBJ.
Clean up OBJ model code
Remove commented code, mainly Printf's that aren't used any more.
Add more documentation comments, and tweak existing documentation comments
Replace ParseVector2 and ParseVector3 with a template ParseVector function
Create a new surface for each 'usemtl' statement in the OBJ file, and fix memory errors caused by TriangulateQuad.
Calculate missing normals, and fix incorrect UV coordinates
Fix construction of vertex buffer for objects with multiple surfaces
Localize curMtl, curSurface, aggSurfFaceCount, and curSurfFaceCount to FOBJModel::Load(), since they are not used anywhere else.
Fix parsing of OBJs without UV references
Internally, I replaced hashtag line comments with C-style line comments, and I replaced each forward slash with newSideSep.
If no UV coordinates are available, add a default vector of (0,0).
Also, remove "this->" from ResolveIndex to make the code a bit cleaner, and fix a minor garbage issue I failed to notice earlier (normref would pick up garbage if there was no normal reference).
Ensure usemtl statements remain intact
It may be a bit inefficient, but I tried modifying the buffer directly, and I got memory corruption errors. In this case, it's a lot better to be safe than sorry.
What works:
- Parsing the model
- Constructing geometry (surfaces) for triangulated models
What doesn't:
- Rendering the model
- Building the vertex buffer
- Triangulating quads
UE1: Add support for Deus Ex format vertex data.
UE1: Group triangles by skin index AND type/flags (preparation for per-surface render style support).
UE1: Add handling of Weapon Triangle (preparation for model attachment support).
UE1: Support flat shaded triangle flag.
