Best ResponseYou've already chosen the best response.1Okay 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.
