2008-05-02Replaced OpenGL12 with SDL's gl/glu/glext units because OpenGL12 was removed ↵tobigun2-9992/+0
from SDL (several years ago? Last update was done in 2004). In addition OpenGL12 was very buggy (see last commit). The new units support OpenGL up to version 2.0 (extensions must be loaded first, see UGraphic.LoadOpenGLExtensions). At the moment, only 1.2 extensions are loaded. Some constants, that were introduced in OpenGL 1.2 and above (like GL_BGR or GL_CLAMP_TO_EDGE) are in glext.pas, so check this file first for missing constants. The MacOS build depends on OpenGL12.pas but has its own file in the MacOSX/Wrapper folder instead of using the JEDI-SDL one. Sorry, that I broke MacOSX build for now but it should be no problem to get this working again. git-svn-id: svn://svn.code.sf.net/p/ultrastardx/svn/trunk@1052 b956fd51-792f-4845-bead-9b4dfca2ff2c
2008-05-02bugfix: USDX crashed while unloading opengl because of a bug in opengl12.pas ↵tobigun1-0/+2
(Glu was unloaded twice, because the handle of the main gl-lib was overwritten with that of glu) git-svn-id: svn://svn.code.sf.net/p/ultrastardx/svn/trunk@1050 b956fd51-792f-4845-bead-9b4dfca2ff2c
2008-03-20- Delphi (in contrast to C/C++) handles floating-point multiplications with ↵tobigun2-19/+13
NaN or divisions by 0.0 as floating-point exceptions (FPE). This is a problem with some libraries which expect that e.g. "NaN * 3.0" is NaN or "4.0 / 0" is INFINITY. - The (strange) default behavior can be changed by setting the control word of the FPU. This is done by assigning $133F to this register via Set8087CW() in delphi. In FPC it was not available for a long time but now it is. OpenGL12.pas contained an own version of Set8087CW() which was totally wrong because the important asm-directives (fclex and fldcw) were missing so it was not of any use. Hence it was removed from the unit so it does not hide the correct FPC version anymore. - This should fix some EDivByZero exceptions in floating-point expressions (as with projectM). git-svn-id: svn://svn.code.sf.net/p/ultrastardx/svn/trunk@962 b956fd51-792f-4845-bead-9b4dfca2ff2c
