OpenMaXwell does not run correctly

It seems that some applications may cause more or less severe problems to OpenMaXwell. For example, virus scan programs can considerably reduce the performance of OpenMaXwell.

Graphic programs can disturb the movie generation of OpenMaXwell. Graphic programs using OpenGL in an unconventional way may even prevent OpenMaXwell from running. It seems that this holds for some versions of Matlab. In this case, no application using the openGL Utility Toolkit (GLUT32.DLL) run on your PC. To test this, you can find many games and other software using GLUT on the web. For a prominent site, click here.


Note that OpenMaXwell uses OpenGL. It might happen that not all of the required DDLs are installed on your system. Especially GLUT32.DLL might be missing. In this case, OpenMaXwell will not run correctly. A message box will indicate the name of the missing DLL.

According to my experience, the standard GLUT32.DLL keeps the processor 100% busy and slows down the performance of all other OpenMaXwell tasks as well as the performance of all other processes running at the same time. To avoid this, I have compiled GLUT32.DLL with a modification that slightly slows down the OpenGL performance. I strongly recommend to use this version that is contained in the ZIP file that contains the latest OpenMaXwell version. Usually, GLUT32.DLL is placed on a system directory such as c:\winnt\system32 but you may also copy it to the directory where you store the executables of MaX-1.

 If another DLL than GLUT32.DLL is missing on your PC, please, report this by email.
