I have a very simple QC comp. that has a Sphere patch, that rotates
around
the x-axis. It looks like it rotates perfectly when the x value is
zero.
However, if I move the x value left (negative) or right (positive) any
amount, you can see that the rotating globe is tilted towards the
center.
All I have is an Interpolation patch from 0 to 360 for 5 seconds
looped,
connected to the sphere patchs X Rotation input, where all other
values are
zero. There's also an image importer that is connected to the
image input.
I think you are simply observing that QC uses a perspective projection
