Re: [Lazarus] OpenGL with Lazarus
What about SDL ? AFAIK, same can use Open GL (and other) graphical backends. -Michael -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

The only thing you gain by using SDL is cross-plattform context creation (which Lazarus provides, too, via TOpenGLControl). But you still have to learn pure, low level OpenGL to use it. It is under active development, and was/is used in many game development, so we know it has good performance too. When used for game development a 2D/3D-Engine is running on top of SDL (for example the Linux version of Quake4 uses SDL but the real work is done by the id Tech 4 engine). All 'we' know is that these different engines seem to have good performance. You gain nothing by using SDL for OpenGL (especially not speed as SDL just provides direct OpenGL access, same as without SDL). It is used in Game Development because it is cross-plattfrom and can initialize your GL context, take care of the sound and input devices. But the real graphics work is done by some engine on top of it. So, yes, it is a good lib and used in commercial games but it is not what the OP is looking for. Both GLScene and the castle game engine are better options. @OP If the development is less game and more visualization you may also take a look at http://asmoday.sourceforge.net.

SDL has its own cross-platform 2D API, but for the OpenGL backend the calls are the OpenGL API.
