Dear Sirs , In c:\fpc\2.2.2\examples\opengl\ directory , there are demonstration programs using OpenGL . With c:\fpc\2.2.2\bin\i386-win32\Make.EXE , it is possible to generate executable files without error . When they are run , they are given exception about missing GLUT32.DLL . In the FPC installation , and in \Windows\System32\ directory there is not GLUT32.DLL . I have found one in http://www.dlldump.com/download-dll-files_new.php/dllfiles/G/glut32.dll/1.0/download.html It worked very well . The important point is that the programs are compiled by FPC . This shows power of FPC for graphics programming . The rest is mathematics , knowledge about how to program graphics which there may be found any kind of books about graphics programming . If GLUT32.DLL is included in FPC installation , it would make easy to run those programs . Thank you very much , Mehmet Erol Sanliturk _______________________________________________ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
