--== GLQuArK ==-- This archive is the source code for GLQuArK.DLL, which comes with QuArK 3.1 in file QUARK31.ZIP. It can be compiled with Delphi 2.0. It is distributed free of charge and without any warranty of any kind. It is intended to be used as either a reference example document for OpenGL programming or to build other, non-OpenGL-oriented QuArK-aware 3D viewers. I will try not to change the communication standards between future versions of QuArK and the rendering modules, so that rendering modules that work with QuArK 3.1 should work with future versions of QuArK as well. The current version of QuArK doesn't explicitely support multiple rendering modules : the user can't interactively switch between several ones. For the time being, you can develope and use alternate rendering modules by renaming them temporarly GLQuArK.DLL and putting them instead of the official GLQuArK.DLL. In future versions, the custom modules will be allowed to have any name, as far as the extension remains .DLL. QuArK will rely on the information-provider routine "InfoQuArK" in these DLLs to query informations about the .DLL file. Armin
