Does this AA solution work for orthographic cameras? #4

Closed Hyperparticle closed 7 years ago

Hyperparticle commented 8 years ago

Thanks for this fantastic AA solution!

I have tried to use this for orthographic cameras, but it appears to do nothing until I switch it to perspective. I may have missed something in the documentation, but I haven't seen anything that clearly specifies what camera types are supported.

Is this only limited to perspective cameras, or am I doing something wrong with orthographic?

Yeah I have the same problem

Yes, currently jittering and AA are enabled only if camera.orthographic == false.

So I just started working on this, I deleted the check, created another projection function for the orthographic camera. Now it just lacks the correct 4x4 matrix, I have copy-pasted the one used by the perspective projection, so if you activate the Frustum Jitter... SURPRISE: it switch to perspective view!
