Nico de Poel	c91e8e6167	Added bounding spheres to node data, used for frustum culling	3 years ago
Nico de Poel	fc281251ea	Overhaul of geometry conversion: - Faces are now tessellated into one or more polygons, based on UV coordinates and texture tiling - Polygons have their own vertex index list and light/UV values per vertex - Lighting is sampled per polygon vertex, allowing for more light samples in general and more refined lighting - There are still problems with reconstruction of vertices for sloped surfaces, but this is enough of a result for a checkpoint commit	3 years ago
Nico de Poel	4f99baea65	Encapsulated GPC-based tesselation into a Tesselator class, which now also produces normalized UVs per vertex-texture pair and a list of Polygon structs with texture and vertex index data.	3 years ago
Nico de Poel	f413e8c47f	First test with GPC to cut faces into multiple polygons, based on a grid of texture boundaries. Reconstruct the texture space (s,t) coordinates back into world space. Store vertices and indices while avoiding duplicate vertices.	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	e0373524ca	Further improvement to lightmapping system: - Added a function to find all faces that contain a given point. This is useful for both sampling lightmaps, and sampling textures later. - New face vertex lighting function simply collects all faces for a given vertex, and samples all relevant lightmaps for it - A whole bunch more experiments that were more complex and that went nowhere - Ironically all this doesn't really change the current quality of the lighting but hey, that's a result too. And this added code will prove useful soon enough.	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	219fc6db32	Implemented an alternative method for computing lighting per face vertex, one that's simpler, faster and that produces better results. Still not quite perfect yet but about where I want it to be for now.	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
