Hi there,
sorry for the huge post.
This code works perfectly, but, if I change the block

gl.glVertex2i(150, 100);
gl.glVertex2i(150, 150);
gl.glEnd(); |
it just doen´t do nothing ... (nothing but a black screen)
The only thing that changed was the fact that it is no longer a GL_TRIANGLE and it is glVertex2i instead of glVertex3f.
I am a newbie on OpenGL, so I would think it is wierd if I missed something on the rest of the code ...
Thanks for your attention and time,
Have a nice day,
