I know some coders have figured out everything, but should I really explain and spoil every part?
I can tell you this without any major spoilers;
- There is no video streaming from harddrive
- The intro/endtro animations are both in memory when playing. The displayer uses up 88% CPU (273 scanlines + syncline = 274/313 = 0.88)
- The audio buffer refills between effects, it doesn't stream during overscan/hardsync. The buffer is 1.5MB large so approx 1 minute demo can run between two refills
- The last effect is a mix of animation and realtime - the cube is obviously not realtime rasterized. It's a 450kbyte animation with 1 byte/texel. The truecolour RGB alpha blending is realtime though, the background is 128 colours and the alpha have 96 levels of transparency plus overflow for both negative and positive brightness
- To be able to fade the dual-frame MPP pictures by Templeton (the pics uses 0.51MB more data on disk so you can add that amount to the "non effect" datas) we need to pre-calculate over 0.8MB of colours before each pic is shown. That's the reason why the intro/endtro animations are not faded, not enough memory to precalc all those colours there
As for the rest of the demo, it's quite normal demo-coding stuff.

What's the anti-troll code?
