PSYCHE Added a sun. Actually, this involved going way down the garden path of computing the projected screen position of the sun, then reprojecting that into my 2D world so I could draw a bloom effect. This all worked great, and I’m very pleased with sorting that out — among other things that would be needed to display targeting icons and whatnot. There’s just the minor little issue that the bloom effect looks awful, so I turned it off (that’s just the generic sun in the image right now.) Also, I’m running into a bizarre problem trying to use glGenQuery to make a render query — this would let me determine how much of the sun is occluded, so the bloom could be faded out in such a situation. But, XCode acts as if it can’t find the actual body of the function, and the internet has been no help whatsoever. Not sure what the story is with that, honestly.
