Post

Since there’s been such a huge influx of people, I figured I should make an intro post. Hey! I’m Aaron, a programmer at @doublefine.com, where I work on engine modifications, cameras, graphics, and whatever else needs to get done. Here’s a video showing the portals that I made for Psychonauts 2.

My graphic programmer brain forced me to spend far too long moving the camera and Raz back and forth through the clipping plane trying to see the magic. The consistency in light and colour from one side to the other was so so good. I think the only tell was a tiny hint in the antialiasing (guessing)

Anti-aliasing /should/ have been consistent when transitioning through the portal (though it's possible there's something I missed). The most likely issue you'd encounter is the blending breaking down at glancing angles. More info in this video at 11:25 (AA) and 19:56 (blending).

Thanks for sharing, I'd not seen this video before, it's great. And yes, AA was a guess, based on some assumptions from previous experiences (ages ago) with stencil buffer nonsense. I had to stop doing pure graphics coding in the end. I couldn't keep up with the pace of bleeding edge developments
