glm::packF2x11_1x10( ... )
glm::uint32 glm::packF2x11_1x10(const glm::vec3 &v)First, converts the first two components of the normalized floating-point value v into 11-bit signless floating-point values. Then, converts the third component of the normalized floating-point value v into a 10-bit signless floating-point value. Then, the results are packed into the returned 32-bit unsigned integer.
The first vector component specifies the 11 least-significant bits of the result; the last component specifies the 10 most-significant bits.
