Summer Day by Mankind [web]
A Summer Day - 64Kb Amiga AGA intro by mankind, first released at the Sea Sex and Soft party 2 (3S2) in perpignan,france on august 1996 The mod chiptune of this intro is also there in the lha. What happiness we can have sometimes... Watch out ! this deals with psychedelism ! Watch out again, the code is quite buggy, but it works on bare a1200 with no startup sequence, and even with UAE. This is the official second release ever from http://www.mankind.com, the first being Aerial on august 1995. The credits go like that: Krabob - Main code (first prod as coder ) chiptune,gfx. Backlash - additionnal code (krabob's asm teacher) Redshift - add. code, gravitationnal/ particle effects theories. For the history, 1995-1996 was a time every amiga coders wanted to improve their chunky drawing techniques. All kinds of techniques was experimented, but fast c2p were only found and widely used around ... yes, 1996. The technique used in this intro for texture effects is quite original: it is direct video memory access with the cpu, using the 68020 'bfins' instruction (bitfield insert and shift) on 4 planes for triangle drawing, which means we kept a planar screen all the times... Well, not -so- stupid for a vanilla1200 at the times... So I finnaly just wrote half the screen lines to make things faster... Another interesting code note is the fact we used realistic physic simulators for 2 effects: Redshift is a university trained astrophysician, and learned us some tricks to apply realistic movements to objects... So a gravitational map actually give their movememt to the particles, and the strange polygons near the end are in fact 2 elastics made of oscillators... Well, these effects were good ideas, but aren't emphasized much (watch scream thy last scream for a better implementation) . What's make it enjoyable to watch 10 years after is more the freshfull chiptune and the feria spirit. Krabob, 01/03/2007
