+
+// This unit contains many needed types, functions and procedures for
+// quaternion, vector and matrix arithmetics. 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.
+//

+ Rotation of the Angle t about the axis (X, Y, Z) is given by:
+
+ | X^2 + (1-X^2) Cos(t), XY(1-Cos(t)) + Z Sin(t), XZ(1-Cos(t))-Y Sin(t) |

+ | XZ(1-Cos(t)) + Y Sin(t), YZ(1-Cos(t))-X Sin(t), Z^2 + (1-Z^2) Cos(t) |
+
+ Rotation about the three axes (Angles a1, a2, a3) can be represented as
+ the product of the individual rotation matrices:
+
+ | 1 0 0 | | Cos(a2) 0 -Sin(a2) | | Cos(a3) Sin(a3) 0 |

+ Mx My Mz
+
+ We now want to solve for X, Y, Z, and t given 9 equations in 4 unknowns.
+ Using the diagonal elements of the two matrices, we get:
+
+ X^2 + (1-X^2) Cos(t) = M[0][0]
+ Y^2 + (1-Y^2) Cos(t) = M[1][1]
+ Z^2 + (1-Z^2) Cos(t) = M[2][2]
+
+ Adding the three equations, we get:
+
+ X^2 + Y^2 + Z^2 - (M[0][0] + M[1][1] + M[2][2]) =
+ - (3 - X^2 - Y^2 - Z^2) Cos(t)
+
+ Since (X^2 + Y^2 + Z^2) = 1, we can rewrite as:
+
+ Cos(t) = (1 - (M[0][0] + M[1][1] + M[2][2])) / 2
+
+ Solving for t, we get:
+
+ t = Acos(((M[0][0] + M[1][1] + M[2][2]) - 1) / 2)
+
+ We can substitute t into the equations for X^2, Y^2, and Z^2 above
+ to get the values for X, Y, and Z. To find the proper signs we note
+ that:
+
+ 2 X Sin(t) = M[1][2] - M[2][1]
+ 2 Y Sin(t) = M[2][0] - M[0][2]
+ 2 Z Sin(t) = M[0][1] - M[1][0]

+ Revision 1.5 2007/05/20 20:28:31 savage
+ Initial Changes to Handle 64 Bits
+
+ Revision 1.4 2006/11/20 21:20:59 savage
+ Updated to work in MacOS X
+
+ Revision 1.3 2005/05/22 18:52:09 savage
+ Changes as suggested by Michalis Kamburelis. Thanks again.
+
+ Revision 1.2 2004/08/14 22:54:30 savage
+ Updated so that Library name defines are correctly defined for MacOS X.
+
+ Revision 1.1 2004/03/30 21:53:54 savage
+ Moved to it's own folder.
+
+ Revision 1.4 2004/02/20 17:09:55 savage
+ Code tidied up in gl, glu and glut, while extensions in glext.pas are now loaded using SDL_GL_GetProcAddress, thus making it more cross-platform compatible, but now more tied to SDL.
+
+ Revision 1.3 2004/02/14 00:23:39 savage
+ As UNIX is defined in jedi-sdl.inc this will be used to check linux compatability as well. Units have been changed to reflect this change.
+
+ Revision 1.2 2004/02/14 00:09:18 savage
+ Changed uses to now make use of moduleloader.pas rather than dllfuncs.pas
+
+ Revision 1.1 2004/02/05 00:08:19 savage
+ Module 1.0 release
+
+ Revision 1.6 2003/06/02 12:32:12 savage
+ Modified Sources to avoid warnings with Delphi by moving CVS Logging to the top of the header files. Hopefully CVS Logging still works.

+ Revision 1.6 2007/05/20 20:28:31 savage
+ Initial Changes to Handle 64 Bits
+
+ Revision 1.5 2006/01/11 22:39:02 drellis
+ Updated to Support Up to OpenGL 2.0
+
+ Revision 1.4 2005/01/05 00:28:40 savage
+ Forgot to wrap a couple of Load_WGL function calls with an IFDEF WIN32. Fixed so now compiles under Linux as well.
+
+ Revision 1.3 2004/08/24 19:33:06 savage
+ Removed declarations of SDL_GL_GetProcAddress as the correct ones are in sdl.pas.
+
+ Revision 1.2 2004/08/09 00:38:01 savage
+ Updated to Tom's latest version. May contains bugs, but I hope not.
+
+ Revision 1.1 2004/03/30 21:53:54 savage
+ Moved to it's own folder.
+
+ Revision 1.6 2004/03/28 00:28:43 savage
+ Fixed some glSecondaryColor definitions...
+
+ Revision 1.5 2004/02/20 17:18:16 savage
+ Forgot to prefix function pointer with @ for FPC and other Pascal compilers.
+
+ Revision 1.4 2004/02/20 17:09:55 savage
+ Code tidied up in gl, glu and glut, while extensions in glext.pas are now loaded using SDL_GL_GetProcAddress, thus making it more cross-platform compatible, but now more tied to SDL.
+
+ Revision 1.3 2004/02/14 22:36:29 savage
+ Fixed inconsistencies of using LoadLibrary and LoadModule.
+ Now all units make use of LoadModule rather than LoadLibrary and other dynamic proc procedures.
+
+ Revision 1.2 2004/02/14 00:09:19 savage
+ Changed uses to now make use of moduleloader.pas rather than dllfuncs.pas
+
+ Revision 1.1 2004/02/05 00:08:19 savage
+ Module 1.0 release
+
+ Revision 1.7 2003/06/02 12:32:13 savage
+ Modified Sources to avoid warnings with Delphi by moving CVS Logging to the top of the header files. Hopefully CVS Logging still works.

+ Revision 1.8 2007/05/20 20:28:31 savage
+ Initial Changes to Handle 64 Bits
+
+ Revision 1.7 2006/11/26 16:35:49 savage
+ Messed up the last change to GLUtessCombineDataProc, had to reapply it. Thanks Michalis.
+
+ Revision 1.6 2006/11/25 23:38:02 savage
+ Changes as proposed by Michalis Kamburelis for better FPC support
+
+ Revision 1.5 2006/11/20 21:20:59 savage
+ Updated to work in MacOS X
+
+ Revision 1.4 2005/05/22 18:52:09 savage
+ Changes as suggested by Michalis Kamburelis. Thanks again.
+
+ Revision 1.3 2004/10/07 21:01:29 savage
+ Fix for FPC
+
+ Revision 1.2 2004/08/14 22:54:30 savage
+ Updated so that Library name defines are correctly defined for MacOS X.
+
+ Revision 1.1 2004/03/30 21:53:54 savage
+ Moved to it's own folder.
+
+ Revision 1.4 2004/02/20 17:09:55 savage
+ Code tidied up in gl, glu and glut, while extensions in glext.pas are now loaded using SDL_GL_GetProcAddress, thus making it more cross-platform compatible, but now more tied to SDL.
+
+ Revision 1.3 2004/02/14 00:23:39 savage
+ As UNIX is defined in jedi-sdl.inc this will be used to check linux compatability as well. Units have been changed to reflect this change.
+
+ Revision 1.2 2004/02/14 00:09:19 savage
+ Changed uses to now make use of moduleloader.pas rather than dllfuncs.pas
+
+ Revision 1.1 2004/02/05 00:08:19 savage
+ Module 1.0 release
+
+ Revision 1.4 2003/06/02 12:32:13 savage
+ Modified Sources to avoid warnings with Delphi by moving CVS Logging to the top of the header files. Hopefully CVS Logging still works.
+
+ Revision 1.3 2003/05/29 22:55:00 savage
+ Make use of new DLLFunctions
+
+ Revision 1.2 2003/05/27 09:39:53 savage
+ Added better Gnu Pascal support.
+
+ Revision 1.1 2003/05/11 13:18:03 savage
+ Newest OpenGL Headers For Delphi, Kylix and FPC
+
+ Revision 1.2 2002/10/13 14:36:47 sg
+ * Win32 fix: The OS symbol is called "Win32", not "Windows"
+
+ Revision 1.1 2002/10/13 13:57:31 sg
+ * Finally, the new units are available: Match the C headers more closely;
+ support for OpenGL extensions, and much more. Based on the Delphi units
+ by Tom Nuydens of delphi3d.net

+ Revision 1.4 2007/05/20 20:28:31 savage
+ Initial Changes to Handle 64 Bits
+
+ Revision 1.3 2006/11/20 21:20:59 savage
+ Updated to work in MacOS X
+
+ Revision 1.2 2004/08/14 22:54:30 savage
+ Updated so that Library name defines are correctly defined for MacOS X.
+
+ Revision 1.1 2004/03/30 21:53:54 savage
+ Moved to it's own folder.
+
+ Revision 1.5 2004/02/20 17:09:55 savage
+ Code tidied up in gl, glu and glut, while extensions in glext.pas are now loaded using SDL_GL_GetProcAddress, thus making it more cross-platform compatible, but now more tied to SDL.
+
+ Revision 1.4 2004/02/14 22:36:29 savage
+ Fixed inconsistencies of using LoadLibrary and LoadModule.
+ Now all units make use of LoadModule rather than LoadLibrary and other dynamic proc procedures.
+
+ Revision 1.3 2004/02/14 00:23:39 savage
+ As UNIX is defined in jedi-sdl.inc this will be used to check linux compatability as well. Units have been changed to reflect this change.
+
+ Revision 1.2 2004/02/14 00:09:19 savage
+ Changed uses to now make use of moduleloader.pas rather than dllfuncs.pas
+
+ Revision 1.1 2004/02/05 00:08:19 savage
+ Module 1.0 release
+
+ Revision 1.4 2003/06/02 12:32:13 savage
+ Modified Sources to avoid warnings with Delphi by moving CVS Logging to the top of the header files. Hopefully CVS Logging still works.

+ Revision 1.3 2006/11/20 21:20:59 savage
+ Updated to work in MacOS X
+
+ Revision 1.2 2006/04/18 18:38:33 savage
+ fixed boolean test - thanks grudzio
+
+ Revision 1.1 2004/03/30 21:53:55 savage
+ Moved to it's own folder.
+
+ Revision 1.5 2004/02/15 22:48:35 savage
+ More FPC and FreeBSD support changes.
+
+ Revision 1.4 2004/02/14 22:36:29 savage
+ Fixed inconsistencies of using LoadLibrary and LoadModule.
+ Now all units make use of LoadModule rather than LoadLibrary and other dynamic proc procedures.
+
+ Revision 1.3 2004/02/14 00:23:39 savage
+ As UNIX is defined in jedi-sdl.inc this will be used to check linux compatability as well. Units have been changed to reflect this change.
+
+ Revision 1.2 2004/02/14 00:09:19 savage
+ Changed uses to now make use of moduleloader.pas rather than dllfuncs.pas
