the camera needs to keep an eye on the player and stay on the same line as the portal. so it moves along it.

and it is required to translate a relative point from one portal to another. which means making a position relative to a portal, rotating it back, then rotating it by the other portal and making it absolut again. Sabe goes for rotations


Hi Dico!

Unfortunately, screen you've posted doesn't show up :<
About shaders and what Rackscha said, I guess using shaders will be faster plus it does that 'cut-off' effect. I've done it differently (cause I'm not familiar with shaders) and just rendered view directly on the texture of the portal model (and I guess this is one of the worst ways to do this). Anyway, I'm still stuck and breaking my brain on how to add player's position/angles into the portal view, so it does look like a whole into the other room (f.e.) not like a flat TV.

Best regards!
