When BufferData is called the first parameter is target - for example, ARRAY_BUFFER. BufferData copies data from the client to a buffer object associated with target. However, buffer objects also...

State charts are good examples of graphics that illustrate the behavior of a system. A state chart can capture the state changes caused by one or more function calls. For OpenGL state charts...

Alfonse, that's a pretty lame attempt at trying to insult me and trivialize my comments.

I can think of lots of ways that graphics could be used to explain concepts. For example, OpenGL has a...

For several months I have been trying to learn OpenGL to go beyond displaying a single 3D object. I have watched a lot of videos, read books, and lots of online documentation. In my opinion, the...

arekkusu, thanks for the tip.

I found ARRAY_BUFFER_BINDING in section 2.9.6 of the 3.2core spec. The spec isn't very clear. ARRAY_BUFFER_BINDING is mentioned only once: "For example, the...

Thanks Dan!

Another quick question about this topic. Let's say I make multiple calls to bind three different buffers to the same target (GL_ARRAY_BUFFER). glVertexAttribPointer is called for each and in each...

Thanks for the replies. I did some experimenting last night on my mac. If I place the calls to glVertexAttribPointer before binding my buffers, I get garbage on the screen. No errors, just...

I have a question about the order of these function calls:

glBindBuffer(GL_ARRAY_BUFFER, buf1);
glVertexAttribPointer(0, 4, GL_FLOAT, GL_FALSE, 0, 0);
glBindBuffer(GL_ARRAY_BUFFER, 0);

Is it...

I'd like to use this post to start a thread on vertex arrays, buffer objects, and vertex array objects. I am sure that a lot of people are, like me, confused about these items. So, I'd like to...

I have downloaded the OpenGL specs for versions 2.0, 2.1, 3.0, and 3.2core. In the version 2.0 and 2.1 specs I see in the table of contents sections for Vertex Arrays and Buffer Objects (sections...

I am new to OpengGL. The tutorials that I have read explain how to pass vertex data to the GPU using vertex buffer objects. I have this working fine for a single mesh. For a scene consisting of...
