I understand why this always comes up, but in this particular case it's particularly 'un-useful'. I can tell you exactly what API calls he makes: on boot he makes API calls the equivalent of PlayGigantic3MinuteWav(), InitOpenGL(), Compile2Shaders(), and then each frame he calls DrawFullScreenQuad() (twice, once to an offscreen texture, once to the screen), and Flip(). All the magic of the demo is in the synth (pure x86 fpu code) for the music, and the sphere tracer / camera choices / colors / fractal equation, for which precisely 0 'API' is used. Put another way, the really amazing thing these days is that we have hardware (cpu, gpu) capable of so many FLOPS that you can do brute force things like sphere tracing complex fractals. the goal, seen in this light, of the demoscene, is to expose the wonder of all that power in visually interesting or arty ways. Seriously, you couldn't have picked a worse example of someone 'leaning on an api'. :) |
