Neat! Can you give a really short description of why this is useful or of the most interesting techincal aspects?
I figure it would make an awesome video-game. Given that it took 30 seconds to render each frame, that's not going to happen as a raytracer. I might be able to get it to work in real time if I run it using that thing where you draw triangles, or better yet, use it to find a few guide points and then just warp a 3d model.
It also might be good for getting people to understand differential geometry or something.
Actually, can you just tell me what's going on in the second movie where the grid appears to stop growing closer?
It's a sky sphere. It's infinitely far away. When you're in part of space that's Euclidean and you're not rotating, it doesn't move. The only reason that it moves at all in the second video is because of how warped space is.
I should add that when running it in a ray-tracer it can only draw sky-spheres, but when running it normally it can only draw triangles. I'm considering making it so one of those can do both.
Your job, should you choose to accept it, is to comment on this thread explaining the most awesome thing you've done this since June 1st. You may be as blatantly proud of yourself as you feel. You may unabashedly consider yourself the coolest freaking person ever because of that awesome thing you're dying to tell everyone about. This is the place to do just that.
Remember, however, that this isn't any kind of progress thread. Nor is it any kind of proposal thread. This thread is solely for people to talk about the awesome things they have done. Not "will do". Not "are working on". Have already done. This is to cultivate an environment of object level productivity rather than meta-productivity methods.
So, what's the coolest thing you've done this month?
