Adding Fast Quadric Mesh Simplification support #25

Closed BastiaanOlij closed 6 years ago

BastiaanOlij commented 6 years ago

Working on implementing this really cool piece of tech: https://github.com/sp4cerat/Fast-Quadric-Mesh-Simplification

This takes in a mesh, optimizes the vertices and faces to a reduction factor and gives you a resulting mesh. Note that due to the way meshes are loaded into Godot multi material meshes will always have seam issues. But in combination with game optimization turning a mesh into a single material mesh with all textures baked into one this will be a powerful automatic LOD tool.

Lots of work left to be done. Need to remove duplicate vertices to solve seam issues. Have to add texture coordinates, etc.

UVs and seams work fine now, last thing to do is normals :)

OK I have normals and tangents working though tangents seem inverted somehow (or maybe they are wrong on the source object). I think it's time to merge this
