- Hello there Amiga freaks!
- ~~~~~~~~~~~~~~~~~~~~~~~~~
-
- This is the final version of our intro G-Force. The compoversion that has
- been spread is not a totally ready version, due to the killing time limit.
- Also, Assembly rules didn't allow usage of disk libraries, so I couldn't
- make the compoversion use my own compatibility library, backstab.
-
- There have been some rumours about the intro being precalculation, or some
- sort of fuzzied chunky2planar-implementation. It really is 2x2 resolution,
- with 1x2 accurate (rastered -- or 'dithered') shading in 16 colors (meaning
- that the edges of polygons are in 2-pix rez and the shading inside polygons
- is in 1-pix rez).
-
- To show that the routine really _is_ realtime, there is a 'free-flight'
- version in the package. This version is AGA only, because making an OCS
- version of this too would have been an overkill :). Please understand that
- pretabling is _not_ the same as precalculation, because pretabling doesn't
- create any limitations to the routine. (Besides, if I could precalc in 8
- seconds, I could make it realtime instead :=)
-
- Even though the compoversion requires AGA, it only uses it for palettes
- and fetchmode (which makes the intro run a 'bit' faster). In the package you
- will also find a version for any Amiga, that runs on 68020 or better.
- Unfortunately a version for 68000/010 would require so much retyping of
- the code (not to mention deoptimizing everything) that I don't consider
- it worth it. And besides, how many A500/A600/A2000 owners there are with
- '000/'010, 2 megs chip and 4 megs fast??
-
- Sorry about the dirty OCS colors, we used palettes that had "small
- scale" instead of full valour from dark to bright, so some colors
- in the palette are doubled etc.. Palettes have been rescaled, so they
- are using colors in much bigger range to cover for the lack of shades.
- It would have been possible to improve these palettes a great deal,
- but I didn't consider it worth the trouble.. *duck*
-
- There are still some "deadline bugs" left in the intro, I didn't want
- to invest energy in fixing "bugs" in sorting the face and so on. These
- could have been done relatively easily, though.. The other 'flicks' that
- look like bugs.. well, I know why they are there, but fixing it in
- this particular routine would need a largeish rewrite (the actual vector
- routine was coded in a big hurry :)
-
- A problem with the music with a4000/040 is due to some special feature
- in '040 that we weren't able to track down (copper interrupt..). The version
- in the package _should_ be free of this problem, even though we haven't
- tested it on an a4000.

-
- External info on the intro:
-
- Most of the complex objects are designed by Branch (on paper!), and
- some minor objects + Pygmy sun was designed by me (Silver Eagle). Three
- objects (SGI logo, spring and the spiky ball) were imported from a
- Silicon Graphics's demo 'Newton', with a permission from SGI.
-
- Tune "Canberra, Australia" was composed by Papaija, size 42302 bytes.
-
- Coding by me (Silver Eagle), except for the modplayer, which was coded
- by Flame.
-
- Special thanks to Christer Ericson whose =very= fast realtime longword SQRT
- routine I used, I didn't have time to do one myself (I got to know about
- "no disk libraries" - rule a few weeks before the party, shocked :).
-
- Special greets to Andreas Björck, and all the IRC people on #amigascne (and
- amiga scene :-).
-
- Have fun!
