Yes you are absolutely right. This is a case of "premature optimization is the root of all evil" but I was wondering if this an okay thing to do in a...

Not a simple question... or answer. A couple observations. If you ask C/C++ compilers for maximum optimization (which you usually do only to...

Thanks for taking the time to answer, I just solved my problem... It was (as usual) a stupid overlook on my end. The X11 display variable was...

Thank you for these resources! This is a great website! :)

Ok, that's good. From that, I infer that: 1) You have called XOpenDisplay(), and 2) It succeeded. Correct?

What mhagain said. So how do you go about diagnosing that? For starters, run "glxinfo" and post the output of that command in a follow-up post...

Hardware. Drivers. Missing WebGL support in the browser. One of these. Any two of these. All of these. Seriously: "Linux platforms like...

If, what you want is not to compile it again in Linux, then the words you are looking for are cross compilation. In that case, here are some links...

Thank you so much GClements. I think the reason why it wasn't issuing any compilation errors is because I was using an older machine. I am able to...

I'm fairly new to OpenGL, and the only stuff I know about .NET is from powershell..... but I would draw colored triangles (two for a square ie....

That's some interesting wording, but that was what I was looking for. I'll more more into it. Thanks!

Near the top of p50, §2.10 says: Table 6.5. "Vertex Array Object State (cont.)" on p281 includes ELEMENT_ARRAY_BUFFER_BINDING.

Often times, you would write your opaque objects first, with depth writes and depth tests. Then when you render your translucent objects, you'd...

Use CMake. It'll generate your Makefiles on Linux and your MSVS project/solution files on Windows. Here's a link to a short example: * Short,...

If you want transparent pixels to not update the depth buffer, then you need to use discard in the fragment shader. This may have a performance...

Tessellation control shader inputs should be declared as arrays, as you'll get a value for each patch vertex. The number of array elements is set by...

Thanks for the follow-up! That's interesting. It sounds like your driver may have some problems tracking and synchronizing changes to GL objects.

Alright guys, I think I've solved the problem. In the end, the problem was not fault of opengl. It was just my sloppy string conversion in the...

Alright so I was wrong about the glGetError. The GL_INVALID_OPERATION comes from a failure to compile/link the shaders most likely. I called the...

Please, refer to this. It just says whether your program is not a program or it did not linked correctly. Please, check the OpenGL errors (with...

Ah, I hadn't included the glGetError. I called the function and it returned OpenGL error: 1282, GL_INVALID_OPERATION. I get GL_INVALID_OPERATION...
