qconvert

matrix3  qconvert(vector4 quaternion)

Converts a quaternion represented by a vector4 to a matrix3 representation.

matrix  qconvert(vector4 quaternion, vector offset)

Converts a quaternion represented by a vector4 to a matrix representation. Applies the offset as a post-translation, so the resulting matrix will first rotate a point by the quaternion and then add the offset.

vector  qconvert(vector4 quaternion)

Converts a quaternion represented by a vector4 into a angle/axis vector.
