AOS4 NOTE: Some scene are slow even on 1ghz cpu. There is many fastor which make such slownes, like little raw cpu power for modern demos, bad opengl realisation for now (2010) with warp3d layer beetwen + some fucntions like trasformation, lighting and such done in SW mode (and not hardware accelerated) and so on. But anyway, its interesting to see. As usual i rewrite FMOD on SDL_Mixer, add window/fullscreen modes and alt. original readme: Credits Martti "Preacher" Nurmikari  Programming Jukka "Grip" Ð”lli  Soundtrack Brett "Firelight" Paterson  XM Player Fabian "ryg" Giesen  Packer .Information and random babble It seems strange to sit here, writing this infofile in the beginning of January.. but the intro is in releasable condition and writing infofiles is my favourite part of the production process, so why not? :) I was originally only supposed to make a demo for BP, but then I was contacted by iq/rgba who was interested in getting something done by me for his ICM 2006 (International Congress of Mathematicians) workshop on realtime mathematics, so I hacked this thing together. Since his deadline and Breakpoint coincide nicely, why not release this here as well? It's not as "entertaining" as some prods I have made, but I think it contains some beautiful visuals. The name is Latin for "before God". To quote Paul Dirac: "It seems to be one of the fundamental features of nature that fundamental physical laws are described in terms of mathematical theory of great beauty and power, needing quite a high standard of mathematics for one to understand it. You may wonder: Why is nature constructed along these lines? One can only answer that our present knowledge seems to show that it is so constructed. We simply have to accept it. One could perhaps describe the situation by saying that God is a mathematician of a very high order, and He used very advanced mathematics in constructing the universe. Our feeble attempts at mathematics enable us to understand a bit of the universe, and as we proceed to develop higher and higher mathematics we can hope to understand the universe better." Included (for the sake of making myself sound smarter than I really am) are: Platonic solids  Just a visualization of the five Platonic objects in classical mathematics. 2d potential field  Also called a "plasma" in some circles ;) two functions are morphed, one is a distance field and one a combination of sine waves... ;) NewtonRaphson fractals  A polynomial function is iterated in the complex plane and the phase angle plotted in a grid. Lorentz attractor  The classical attractor system, arising from all sorts of physical phenomena, visualized. Rossler attractor  Arises at least from oscillation in chemical reactions. Diffusion limited aggregation  Simulation of diffusing particles, where the particles stick to each other or the edges of the cube holding the simulation when they meet. Voronoi diagram  Divide the plane into sets through generator points calculating which point is the closest. Also known as cellular texture ;) Curves  Just a bunch of curves in three dimensions. Pick a bunch of points, for each point, give two angles, their derivatives and speed, then just iterate, plotting the trajectory. Nothing mathematical in it, but it looks pretty. 2D vector field  It may look like a tunnel, but it's not. It's just a bunch of particles moving in three different vector fields, varied over time. Breadthfirst search  Tree patterns are generated using fibonacci numbers (first branch gets two children, the next three, then five..), which are then visualized per generation. Fibonacci numbers grow big fast, so only generations up to six are used. IFS fractals  A set of transformations is defined for the twodimensional plane. For each iteration, one is picked randomly and the pixel plotted, which results the pixels to converge towards a set. The transformations are varied over time, to animate the fractals. (any set of transformations will make a fractal, but because most of them look like shit, the original parameters which I tweaked are from Paul Bourkes site) 3d vector field  Particles in threedimensional vector fields. Pretty. Left out, are, some stuff that you may or may not see in the future ;) .Contact Preacher : syksyisin()gmail.com Grip : grip()jippii.fi .Finally Greetings and love to all of my friends, you know who you are.
