Detailed Description

Short vertex class for normalized vectors.

All the vertex coordinates are stored in signed 16-bit fixed-point format with 1 bit for the sign and 15 bits of mantissa. Encoded values hence may only vary from -1 (0x8000) to 0.99997 (0x7FFF). It can be considered sufficient to store normal vectors.
