Okay well in OpenGl you use a 4x4 augmented matrix, where the first 3x3 matrix has to do with it's rotation, the column matrix 4 is where in the world it is, and the 4th row is the transitioning of the matrix. Since you want a homogeneous matrix you will set the 4th column to all 0's. The 4th row would be your (2,3,4) Now about a point you would set that yourself in the 3x3 I believe as x = 3, y = 1, and z = 0. \[\left[\begin{matrix}3 & 0 & 0 & 0 \\ 0 & 1 & 0 & 0 \\ 0 & 0 & 0 & 0 \\ 2 & 3 & 4 &0\end{matrix}\right]\] should be your matrix.

Np, hope that works.... I normally have GlRotate() and other goodies to do the work for me :P.

Most schools like to teach you how to do it 100%, but with IDEs and such you don't need half of the crap they teach you.

OpenGL is awesome, but hard. IT's also overkill for a lot of things, but just one of the only 3D Libraries out there....

I code in Java and we have now JavaFX which has an Open GL wrapper.... I don't need all the lighting and shaders and poo poo :P.
