Nico de Poel	f35fd7287e	Made an attempt at detecting T-junctions in geometry and correcting the vertices for that. It sort of works but it doesn't have the desired effect yet. Back to the drawing board.	3 years ago
Nico de Poel	b43dff99a2	Fixed a floating point rounding error preventing faces from being found for some world-space points. Fixes lighting bugs in a few areas.	3 years ago
Nico de Poel	ca08893253	Relaxed vector equality margin of error a little bit, hopefully leading to less instances of faces not being found for a given point	3 years ago
Nico de Poel	caaccee1dd	Export model data for dynamic world objects	3 years ago
Nico de Poel	fb66f93b46	Provide some additional data in the PS1 BSP file, including linked list pointers for leaf-based polygon sorting	3 years ago
Nico de Poel	c91e8e6167	Added bounding spheres to node data, used for frustum culling	3 years ago
Nico de Poel	93551117b1	Added surface flags, allowing for rendering of water surfaces	3 years ago
Nico de Poel	ef9adf8de0	Introduced some matrix math to properly construct a texture space transform, that we can also invert to create a transform back to world space. Finally our tesselated polygons are working perfectly!	3 years ago
Nico de Poel	568f2450eb	Added a new lighting sampler to take advantage of the improved lightmap indexing: use a pseudo-random jitter pattern to take multiple light samples in an area around the sample point, from all surrounding faces at a shallow angle. This further smooths out the lighting and reduces artifacts, while also better representing each face's entire lightmap.	3 years ago
Nico de Poel	fb3d1ac6a1	Upgraded dot product and cross product-related functions to doubles, to improve accuracy of various calculations	3 years ago
Nico de Poel	161ef0acee	Improved lightmap sampling accuracy. The generated UVs now more closely match what Quake is doing, we can reject invalid UVs, and we're getting less false rejects of valid faces to sample from.	3 years ago
Nico de Poel	d84a14973b	First pass at converting texture info to PS1 VRAM data. Not quite right yet but it's starting to work.	3 years ago
Nico de Poel	5137fe0a15	A bit of cleanup and moved the facesWithPoint function to world_t, for easier reuse	3 years ago
Nico de Poel	bf3bf810f6	Added computation of face area by projecting its vertices onto its plane and then generating a bounding box. Will be used for determining tessellation subdivisions.	3 years ago
Nico de Poel	e65ce7b673	First attempt at calculating lighting per face-vertex with smoothing based on the angle between faces, using edge adjacency to determine neighbouring faces. Not quite right yet but it does get a result, and it's given me a good idea of what the correct solution for this should be.	3 years ago
Nico de Poel	86343e96a9	Added export of PVS data	3 years ago
Nico de Poel	c429529e88	Fixed lightmap sampling: - Implement bounds calculation per face instead of for all faces, which was silly - Face lightmap width and height calculations now match what Quake does - Added an export function for lightmap data, to make debugging easier - Include face baselight into vertex lighting, if/when that ever makes a difference	3 years ago
Nico de Poel	9f9bf49a86	Sample lightmaps to accumulate and average lighting values per vertex, then store those in the exported BSP file.	3 years ago
Nico de Poel	2f3facc4d8	Added a few more bits of BSP data, fixed edge list which is in fact an array of ints; the documentation was wrong.	3 years ago
Nico de Poel	bd339fc737	Separated file loading from BSP processing, making it easier to use data from different sources and also ensuring everything gets cleaned up properly at the end.	3 years ago
Nico de Poel	8f82f467a0	First import of PS1 MDL/BSP tools project, long overdue	3 years ago
