It is specifically designed +// for geometric calculations within R3 (affine vector space) +// and R4 (homogeneous vector space). +// +// Note: The terms 'affine' or 'affine coordinates' are not really correct here +// because an 'affine transformation' describes generally a transformation which leads +// to a uniquely solvable system of equations and has nothing to do with the dimensionality +// of a vector. One could use 'projective coordinates' but this is also not really correct +// and since I haven't found a better name (or even any correct one), 'affine' is as good +// as any other one. +// +// Identifiers containing no dimensionality (like affine or homogeneous) +// and no datatype (integer..extended) are supposed as R4 representation +// with 'single' floating point type (examples are TVector, TMatrix, +// and TQuaternion). The default data type is 'single' ('GLFloat' for OpenGL) +// and used in all routines (except conversions and trigonometric functions). +// +// Routines with an open array as argument can either take Func([1,2,3,4,..]) or Func(Vect). +// The latter is prefered, since no extra stack operations is required. +// Note: Be careful while passing open array elements! If you pass more elements +// than there's room in the result the behaviour will be unpredictable. +// +// If not otherwise stated, all angles are given in radians +// (instead of degrees). Use RadToDeg or DegToRad to convert between them. +// +// Geometry.pas was assembled from different sources (like GraphicGems) +// and relevant books or based on self written code, respectivly. +// +// Note: Some aspects need to be considered when using Delphi and pure +// assembler code. Delphi ensures that the direction flag is always +// cleared while entering a function and expects it cleared on return. +// This is in particular important in routines with (CPU) string commands (MOVSD etc.) +// The registers EDI, ESI and EBX (as well as the stack management +// registers EBP and ESP) must not be changed! EAX, ECX and EDX are +// freely available and mostly used for parameter. +// +// Version 2.5 +// last change : 04. January 2000 +// +// (c) Copyright 1999, Dipl. Ing.
