3D models of millions of triangles invariably repeatedly use the same 12-byte unit normals. Several bit-wise compression algorithms exist for efficient storage and progressive transmission and visualization of normal vectors. However such methods often incur a reconstruction time penalty, which in the absence of dedicated hardware acceleration, make real-time rendering with such compression/reconstruction methods prohibitive. We present a new method for the compression of normals that does not… CONTINUE READING
