During my work on GLScene I created a helper unit for all kind of vector and matrix computations. Since this unit might be of general interest it is offered here as separate download.

• Vector functions, e.g. addition, subtraction, negation, combination, dot product, cross product, linear interpolation (LERP), angle computation etc.
• Matrix functions, e.g. creation of rotation, scale and translation matrices, adjoint, determinant, inversion, multiply, transposition etc.
• Quaternion functions, e.g. creation, conjugation, multiplication, convertion to/from matrices, spherical linear interpolation (SLERP) etc.
• A few mathematical functions not found in older Delphi versions.
