I recently compiled some of my older pre-unicode code, and found the string type had been upgraded to support unicode while the opengl code was still...

Hello there. I've seen that the color to go into the shaders was specified as a vec3 so 3 floats for each RGB channel. 1. Isn't this a waste of...

Dear Admins, Please do not roll your eyes about the upcomming post, coz i know these questions have been asked a million times before, but after...

So I try to get the luxury of a decent depth buffer resolution but so far only see the horrors of z fighting. Here is what I "understand": ...

Hi, developers I am making some 3D volumes from x,y,z, colorlevel data using OpenGL ES 2.0 in Android. so the volume created as like follows. ...

Hi there, I am a total beginner to coding. Is there any existing Open GL Glut code which allows One corner of the square to move when you click...

Hello, Simple question about GLSL and fragment shaders. May I return the "final color" early if I don't need to do any further processing in the...

With a GDC presentation on glNext in less than two weeks, I thought it would be good to get final predictions on the nature of the API. So here are...

In the images below, I believe it is clear that I've properly linked what I need to. I am trying to build and run the program but it fails on these...

Hello, I'm new here :) I've loaded a 3d model in my opengl program and I'm able to render it. The triangles are pure white, and the background is...

Hello, I know folks have helped me in the past on this and I truly believe I am almost there. So, after much work I believe my directional...

Hello there. I've read about different compression formats out of which I came to prefer s3tc and etc (maybe astc but it's a bit slower at real-time...

Can opengl help me to fill some holes in mesh? Exist a function that given a 3d hole contour give me the triangulation that cover it?

Hi guys, I need some kind of information about layering. Is there any relationship b/w layering and how many textures supported by open...

Hi ! I am using the code below to pass an image from a FBO the a fragment shader. My problem is the rendering of my image is upside-down, the...

I've been working on this for weeks and have tried a lot of things, so hopefully someone here has a clever solution. I have a planet model (a sphere)...

I am working on a project where i am working on the parameterization of a mesh as a 2D array. Anyway, at this point i had to switch to OpenGL and as...

Hi! I'm really stuck. I'm rendering to a FBO at 4x screen resolution for the 4xSSAA I'm trying out; however, when I call glViewport at any...

Hello there, is there any way to draw to multiple render targets at once which have different sizes or number of samples? It has not been possible...

Hello, So I have been banging my head against the wall on a GLSL shader issue; essentially my lighting is uneven and weird. See my picture...
