[Gambas-user] Open GL help needed

[Jaap Cramer]

Hi

Sorry I had send my question twice. I recently enabled the mailing list and thought my message did not get through... 

I solved my rotation-problem. I had to enable the depth with the line Gl.Enable(Gl.GL_DEPTH_TEST)
All rotations (x,y and z, work now properly)

Remains the 2 little odd things:
* set focus behaviour
* gb.sdl.info and gb.sdl.list have to be contained in next ubuntu packages

thanks!
Jaap

Hi!

 

 I've written a litte program wich uses Open GL. I draw the triangle. I discovered some

strange behaviour. Nothing is drawn, unless I set the focus on something else, and then on

the GlArea. Which is strange, i think.

 

 However. That is not my MAIN problem. I dont understand how to use the Gl.Rotatef function.

The button 'rotate' switches this function on and off. When it's Off, the triangle is

correctly draw. When the value in TRUE, something starts moving, but it is to close: a huge

green area, and after a little while it moves left, and then comes back... It looks like a

rotation but to close. I hope my description is clear, and someone is able to help me.

 

 I use Gambas 2.7, Ubuntu 8.10 And the GambasGears demo is working properly (After I put the

gb.sdl.info and gb.sdl.list in /usr/share/gambas2/info. Ubuntu package error).
