I am using FREEGLUT under LAZARUS/FPC. No problem. Not very
complicate!!
If it fits to your purpose, I do not have a big
experience, bug I may help you to start, even in french if better!

Hi Lazarati
I have two questions:
1. Have there ever been a Free Pascal implementation of OpenGL? I would
like to learn OpenGL and was wondering if I will be forced to use C++/C or
if there are other options.
2. I know there are (or have been) various OpenGL Lazarus components (e.g.

SDL has excellent cross-platform support, and can use multiple low level
graphical backends to suite each platform. It is under active
development, and was/is used in many game

Ah, you seem to be right. SDL has its own cross-platform 2D API, but for
the OpenGL backend the calls are the OpenGL API.

I guess TOpenGLControl could work with Delphi, too.
Feel free to create a VCL backend.
A QT backend is missing too.

Hi Juha,
IIRC, Freepascal/Lazarus uses the units GL.pas, and GLU.pas as opposed to
Delphi's OpenGL.pas.
I think this is correct, and I hope this helps :)

Yes, that is the easy part.

Are there any conversion guides or examples of how OpenGL Delphi program can
be converted to Lazarus.
I would try to automate it with Delphi converter but I don't know much about
graphics programming myself.
I am testing the converter with DeleD 3-D program which would be an extremely

I succesfully ported my Ballanced Game from Delphi OpenGL to Lazarus OpenGL (
Linux, Win compatible )

If you mean the package lazopenglcontext: no, this is a ToDo.
In general: yes, you can use opengl with qt.

Compiz/linux currently is very touchy depending on your card, kernel and distro
(xorg version).
If you have say Ubuntu 9.04 with kernel .28 and the new xorg and you have intel

pretty much screwed when it comes to
Dear Mattias,
I think that is related to how lazarus manage opengl. I tried another
example with TOpenGLControl and I get the same behaviour.
