vbo

Considering OpenGL 2.1, we all know that glBegin and glEnd are the devil. Should I use only VBO to render 3d primitives (I can't find VAO in that version, weren't there already?)? Should I still use the matrix stack (why not?)? Should I still use glFrustum? Can I take advantage of shaders in GLSL 1.20? Where can I find a tutorial for VBO in OpenGL 2.1 and the "correct" way of programming in it?

Also how am I supposed to animate something. Like a cube moving around an object or a player moving in the scene (static vbo data + shader?)?

Note: Take your time to answer this question, I'll accept an answer tomorrow.

I have migrated my code from OpenGL ES 2/3 to OpenGL 3 (I added bunch of defines and abstract classes to encapsulate both versions, so I have both in one project and compile only one or another). All I need to change was context initialization and glClearDepth. I dont have any errors. This was kind… >>> More

Say, I send 10 polygon pairs (one polygon pair == one 2d sprite == one rectangle == two triangles) into OpenGL ES 2.0 VBO. The 10 polygon pairs represent one animated 2D object consisting of 10 frames. The 10 frames, of course, can not be rendered all at the same time, but will be rendered in particular… >>> More

I have a MD2 model loader, I am trying to substitute its immediate drawing function with a Vertex Buffer Object one....

Currently I am working on a project in which I generate geometry based on the players movement. A glorified very long trail, composed of quads.

Initializing and drawing a mesh using OpenTK

as seen on Game Development - Search for 'Game Development'
I'm implementing a "Mesh" class to use in my OpenTK game. You pass in a vertex array and an index array, and then you can call Mesh.Draw() to draw it using a shader. I've heard VBO's and VAO's are the way to go for this approach, but nowhere have I found a guide that shows how to get Data Video… >>> More
