Title: Opengl Buffer problem
Post by: slimmeke on September 09, 2013, 08:08:44 am

Hey guys

I have a problem using Opengl buffers with SFML.
I do not know if that is a SFML problem or an Opengl problem.
You can find source and images at:

Hope someone can help me with it.

You must disable all your buffers before drawing with SFML.

Tnx Laurent.

Sorry for asking is it possible to give me some example code?
I do not know a lot about Opengl buffers yet.

If you mean examples regarding OpenGL buffer objects in general:

http://www.opengl.org/wiki/Buffer_Object
http://www.opengl.org/wiki/VBO_-_just_examples
http://www.songho.ca/opengl/gl_vbo.html
http://nehe.gamedev.net/tutorial/vertex_buffer_objects/22002/
http://lmgtfy.com/?q=OpenGL+VBO

If you mean interaction between SFML and OpenGL buffer objects, there are none.
The closest there is is the tutorial page on using sfml-graphics side by side with OpenGL. The rest you have to figure out by yourself.
