### Correct view-space transform

I am attempting to model a simple graphics pipeline (i.e. Local->Word->View->Screen->2D spaces). I've been looking at the algorithm required to transform from world to view-space and using the ...

### Creating an Object Orientated Bounding Volume

I'm attempting to test out the maths behind bounding volume algorithms (prior to ray tracing) using MATLAB. So far, I have successfully created the relatively trivial axis aligned bounding volume, ...

### Applying 3d transformation to cuboid

I have the 8 vertices of a cuboid (red points)(XYZvox) with known distance in millimetres (vox to mm) between each vertex which I transform in 3d space using the 4d transformation matrix (M). I am ...
