Notable vector parts?
Some of the finest 3D vectors seen on the C64, atleast of the top of my head are:
The Last Traktor 3/Hz - amazing flatshaded stuff, EOR-filling taken almost to perfection (I can't recall seeing it much improved upon in demos since).
One-Der/Oxyron - The gouraud shading just kicks, sure some of the more complex objects may run a bit slow, but just the fact that it handles objects other than your standard convex ones is fantastic. Also, the first tetrahedron runs at a pretty respectable framerate.
Natural Wonders/Oxyron - Dither vectors, smooth and nice looking, simply taking things to another level.
Anyone have any other notable examples of great 3D stuff taken to almost perfection in a C64 demo to share? Or perhaps the first instance when something was seen?

IIRC Vector Victory calculates coordinates between objects, so only linedrawing (and maybe line clipping) is real time. I think scroll text tells that clipping code is from Fighter Bomber. |

Desert Dream springs to mind. Not sure how fast it is, but the look'n'feel of fly-by scenes at the pyramids is very impressive and Amiga-ish.

When it comes to precalced vectors I think many Hollowman-demos kicks. |

What if we start talking things like texturemapping in 4x4? I seem to recall seeing a routine that the coder said was one of the fastest texturemappers, and that it was so super-optimized that somehow he couldn't use col $0f in it!? Can't remember which demo though.
Then AEGs demos have had some really fast texturemappers as well... |

erh, that was me boasting stupidly here:
Larch
compared to the polish tmappers I have checked I had a tighter inner loop indeed.
but this one has faster texturing by the looks of it:
Nothing But Code
no 16 bit adds / pixel probably, but cheating somehow?
the fastest tmapping imho is here:
Outbreak
but its 'cheating' as hard as it can, you can see that on the quality of the textured object :) |

Thanks Oswald, Larch and Outbreak were the two demos I were thinking about!

Sounds like material for the "world firsts and world records" article on codebase?

AEG's 4x4-texturer in "Outbreak" may be fast, but it's small, low on polygons, and the texture is jumping around like madness :/. Well, it's just me showing my bad side again ;). |

"yes it bugs, but hey, it's fast" =) thats what he told me about his sphere mapper anyway :) |

Sure hope none of these old tmappers are anywhere near my 7 cycles/pixel WIP. I also have an even faster goraud-shader on the way.
Just so you know.
