Was just a quick exercise of creating a typical trackloader (was going to make the demo a two side demo) but decided to release it as it is and release some other gfx / audio inventions as seperate tech demo's

Information on the demo parts as follows

Features particle dissolving (Algotech logo) and wobble text along with a 5 screen high bitmap (not fake boobies this time! :-))
Woman (Page 3 - Poppy)

The entire bitmap is in memory and decompressed in realtime via run length decoding. Does not use VSP hence nearly all the processing time is spent on plotting the bitmaps. Features color bitmap fader

Intro loader pic
Utilises custom spatial dithering to increase the appearance of shades (far more superior than the usual floyd steinberg methods)
color clashes are reduced by utilising sprite underlays (MUCSU mode). Woman - Kristanna Loken

Woman rotator
Video decoding in realtime utilising my face matching vq routine which analyses video and gives more importance to choosing facial
features for the codebook. Utilises bit based delta decompression compressing each frame to around 32bytes to 1000 bytes. Woman (Page 3 - Poppy)

Full screen distorter
Running at 50 frames per second. 320x200 4 color bitmap distorting in x and y. (Woman - Sylvia saint)

logo distorter tile
utilises additional tile based compression (used as a filler while next part is loading)

FLI per line with multicolor sprite underlay - The ultimate non interlaced gfx quality. Utilises Pal blending (Woman - Sylvia saint)

Loop animation
Tile based VQ decompression compressing each frame to max 240 bytes (usually around 80-100 bytes or less) Used as a filler while next part is loading

Bitmap rotator in x position with the ability for each scanline to have a different rotate offset.

Multiple Dancer
24 dancers on screen at once each with a different animation frame offset

Color VQ
Realtime decompression in bitmap mode (16 colors) frame rate leaves a lot to be desired. Optimised version will be in next
movie demo. This is merely to show the quality that can be achieved in standard multicolor mode. (Woman - Sylvia Saint)

Interlace pic
Interlaced charpic used as a filler while next part is loading (Woman - Sylvia Saint)

Large scroller which bounces across the screen with each pixel line having a different offset

Ok. Ok. I will release the converter soon. An example of the color mixing capabilities in this mode. (Looks awful on emulator without true 50.12 refresh rate, but near photoquality on TV) - (Woman - Sylvia Saint)

The End
Another picture utilising Spatial Dither (In MUCSU mode) (Woman - Sylvia Saint)

I was honestly prepared to say "meh, another prod featuring boobies rendered with bathroom tile sized pixels" but wtf. Both converters and actual implementations are really cool. Here is my thumb for it.

What happened to Sylvia Saint btw.? Is she retired?0

I quite enjoyed this display of coder p0rn. And hey, if you're gonna make p0rn you need a p0rn star, right...? :D

Nice, especially liked the distorters.

So far the best C-64 demo this year for me.

Totally outstanding in many aspects. Not only sweets for the eyes, but the sweets are well done. Love every bit of this demo. MR-FLI rocks! Man I thought I saw 720p on the C-64 for a while :) Keep up the good work mate!

Great distortions, twister and multiple dancers.

An ode to your favorite porn star in the form of a c64 tech demo is probably the most nerdiest thing I've seen this year. Not that I'm judging (much), but it felt somewhat creepy too. %-)

awesome tech, but it seemed put together rather sloppily.

Porn: The real reason why computers were invented. I love the 24 dancer!

Very sexy! Keep it going like this! :) I like Algotech demos, they remind me games in type of "Strip Poker" from the old days. This one is probably the best demo from Algotech so far. Highly enjoyable :)

i don't know what to think. music is nice but the chicks are meh. the effects are nice. i can't say anything on the technical part but i'll thumb it up. even if the chicks are meh.

Girls, girls, girls...
Small amount of porn + a lot of coder porn = Algotecher

wow... I didn't expect that long demo just now! Algotech trademark is now made just by seeing soo many pr0n pictures/movies.. hehe! I though that the red-green-blue girls animations will get flip to cyan-magenta-yellow and a white background.. I don't know why.. ;-P

Pretty cool codewise I guess.
