- * Class for representing a direct local frame composed of 3 orthonormal vectors T (tangent), B (bitangent) and N (normal).
- * This class can compress/decompress a local frame, switching from its explicit representation (3 vectors) to its compressed representation (1 vector).
+ * Class for representing a direct right-handed local frame composed of 3 orthonormal vectors T (tangent), B (bitangent) and N (normal).
+ * This class can compress/decompress a local frame, switching from its explicit representation (3 vectors) to its compressed representation (1 vector composed of the Euler angles).
* Usage :
* VEC3 T,B,N ; // current set of orthonormal vectors composing the direct frame.
* LocalFrame lf(T,B,N) ; // Constructor from explicit expression.
