Yeah, GTA 4 is starting to do some pretty cool things with the sound rendering. I don't use OpenAL; I am doing all the mixing myself and then streaming it to the SDL audio wrapper. I don't think OpenAL really does much of this actually; it mostly just does the panning and distance attenuation. It ha...

Yet another blog post, about 3D acoustics.

A couple more blog posts, one about the movement stuff, and one about controlled intersections.

I could change the fitness to encourage standing, but I think that normal behavior is already pretty well-studied, and can be done more easily by other means.

I guess skin and fat would sag less in lower gravity, but I don't think it would affect the actual aging process. On the other hand, on the moon they would never be in direct sunlight (assuming they didn't create an atmosphere so they could go outside), so they would not have any premature skin agin...

I think that your body would be long enough that gravity at the closer end would be much higher than gravity at the farther end, and this difference would tear you apart.

I like Blender a lot. I used it pretty extensively when I was practicing 3D modeling.

I was using http://onesadcookie.com/svn/libBinaryIO/ for low-level file reading and writing, which may have done something strange with the integer byte order.

Does it support dithering? That would help a lot with the color banding.

I think fire damage is considered 'sharp' damage, so it does not heal and causes death. I don't remember exactly how fast it causes damage, but I think it infilcts it at a linear rate of about 30%/second.

I don't see how a one-dimensional infinitely long train track with time being the train could be affected by gravity, since as far as I know, time doesn't have a physical form that gravity could manipulate. Gravity is not a force according to the general theory of relativity; it is a curvature in s...

All genetic algorithms work by starting with a base population of random genotypes, and then evaluating their fitness, and populating the next generation with random variations of the most fit. In this case the genotype is a graph of oscillators that can be connected to the ragdoll joints, and the m...

I don't think there is any question that special relativity is the best model of time. It makes predictions that have never been contradicted, and is essential to modern astronomy and related fields like GPS triangulation.

I am not sure if you are being serious, but people do age in space at the same rate people on Earth do. If you insist on taking gravitational time dilation into account, people in space will actually age slightly faster because time is less distorted around them by gravity then it is for people on E...

The evolved movement thing is mostly for me to practice using machine learning techniques, and also see what crazy movements a ragdoll might come up with without any of our assumptions about how humans should move.

Pretty cool. The cel-shading and animation looks good. Pattern bosses are always fun :) Bug report: If I change the focus (by clicking on another program) while it is loading, it crashes with "The method call is invalid. For example, a method's parameter may not be a valid pointer." Sugges...
