Wheelchair / CAD model processing

Processed an existing CAD model of a wheelchair for real-time rendering. Original CAD model was created by Tom Saey: https://grabcad.com/library/wheelchair--5

Polycount was reduced from ~567k to ~45.5k triangles. Shading is achieved solely by geometry, using hard edges and face-weighted vertex normals. Geometric detail should hold up on close inspection, for example in VR. Tiling materials to be used for surfacing.
