I am facing a very frustrating issue with my computer right now. I successfully upgraded to Ubuntu 12.10 this afternoon, but after the upgrade, the graphical user interface seems completely broken. To be more specific, I can not get the Unity bar to appear on the right.
I have tried many things,…

What should I learn? OpenGL 4.1 or OpenGL ES 2.0?
I will be developing desktop applications using Qt but I may start developing mobile applications in a few months, too. I don't know anything about 3D, 3D math, etc and I'd rather spend 100 bucks in a good book than 1 week digging websites and going…

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…

I was doubting: I'm writing a cross-platform engine OpenGL C++, I figured out windows forces the developers to access OpenGL features above 1.1 through extensions.
Now the thing is, on Linux, I know that I can directly access functions if the version supports it through glext.h and opengl version…

I am currently porting a demo from XNA to DirectX which, as I understand it, both have coordinate systems with different handednesses.
What are the things I need to bare in mind when converting between the two? I understand not everything needs to be changed.
Also I notice that many of the 3D…

I am trying to import a scene into my application from an fbx file.
In 3DS Max, the scene and it’s local translations are as follows:
Root (0, 0, 0)
'-Sphere001 (-15, 30, 0)
' '-Sphere002 (-2, -30, 0)
' '-Sphere003 (-30, -20, 0)
'-Cube001 (35, -15, 0)
This is the code that I am using to get…

I've got 6 points in 3D space: A,B,C,D,E,F, that represent 4 vectors. AB is perpendicular to AC and DE is perpendicular to DF.
I need to find a transformation matrix M, that transforms AB to DE and AC to DF. In other words: M·AB=DE, M·AC=DF
If no scaling was involved, this could be solved with a…

I'd like to know how to get the rotation matrix for the transformation from one cartesian coordinate system (X,Y,Z) to another one (X',Y',Z'). Both systems are defined with three orthogonal vectors as one would expect. No scaling or translation occurs. I'm using OpenSceneGraph and it offers a Matrix…

I'm not really sure how to expand on this other than to say that it appears that my LWJGL seems to have different coordinate systems for the Mouse and for painting Textures. It seems that Textures have the usual Java2D way of putting (0, 0) in the upper-left corner, while the Mouse goes by the more…
