octEncodeInRange
external fun octEncodeInRange(vector: Cartesian3, result: Cartesian2, rangeMax: Double): Cartesian2(source)
Encodes a normalized vector into 2 SNORM values in the range of 0-rangeMax following the 'oct' encoding.
Oct encoding is a compact representation of unit length vectors. The 'oct' encoding is described in "A Survey of Efficient Representations of Independent Unit Vectors", Cigolle et al 2014: http://jcgt.org/published/0003/02/01/
Return
The 2 component oct-encoded unit length vector.
Parameters
vector
The normalized vector to be compressed into 2 component 'oct' encoding.
result
The 2 component oct-encoded unit length vector.
rangeMax
The maximum value of the SNORM range. The encoded vector is stored in log2(rangeMax+1) bits.
