I\'m working on a 2D game in LWJGL. I have successfully rendered QUADS with textures using glBegin but moving to VBOs turned out to be a big undertaking. At the moment I can switch between the vbo and

I\'m just starting out using VBOs (using SDL/glew). I\'m trying to start out using the simple example of a cube - actually at the moment just the one face of a cube - but I can\'t get anything to disp
My app writes all of my geometry data to VBO\'s for performance, but I n开发者_运维知识库eed to read the vertex data during the program execution for ray triangle intersection testing. I noticed that

I\'m trying to share create four QGLWidgets with the same GL3 context so I can sha开发者_如何转开发re a VBO between them.I\'ve been doing this for a while with just one widget, but it wasn\'t shared w
I have a few hundred VBOs.I want to only draw a subset of the VBOs each frame. Is there anything faster than binding and drawing each VBO?Is there a batched draw command for multiple VBOs?
I have a problem with QGLBuffer. I\'m trying to implement a dynamic VBO with Q开发者_运维技巧T + Opengl.
I\'m trying to copy vertex data from a texture to a vertex buffer, and then draw the vertex buffer. As far as I know the best way to do this is to bind the texture to a fbo, and use glReadPixels to co
Has anyone managed to export a OpenGL VBO into an external file format at runtime? I\'d be grateful for any pointers in the right direction, since I h开发者_如何学Pythonave no idea of how I would go a
