emkay Posted June 4, 2007 Share Posted June 4, 2007 http://atari.fandal.cz/detail.php?files_id=476 In the first part it shows 256 colours 3D with a "shine through-sphere" and in the 2nd part it shows a rotating cube with 16 colours and plays a 4 channel MOD in the background. This is even more impressive than Numen to me. Quote Link to comment Share on other sites More sharing options...
Allas Posted June 4, 2007 Share Posted June 4, 2007 It an interesting demo using APAC mode. I don't remember another demo that use this mode. Quote Link to comment Share on other sites More sharing options...

This is even more impressive than Numen to me. Well, in fact I think it's not a 4ch module, but just several 1-channel sample loops played in a predefined order. Still an interesting production though Quote Link to comment Share on other sites More sharing options...
Heaven/TQA Posted June 4, 2007 Share Posted June 4, 2007 its not a bad production. never heard of that and the apac mode is ok btw. but if using apac makes we wonder why not using TIP (ok. not knew back in 1999). for TIP the DLI is the nearly the same...

Still an interesting production though Actually, the demo plays digitized music in a quality that several other players do not reach even when switching of the screen. Additionally it shows huge and colourfull moving objects. Quote Link to comment Share on other sites More sharing options...
Rybags Posted June 4, 2007 Share Posted June 4, 2007 The key to good digitized sound replay is to only go for one or two per scanline - and to be consistent with the intervals, ie- compensate for DMA fluctuations. Conveniently, the PAL and NTSC line rates are very close to 16 KHz which makes creating samples and importing from PC applications easy. Agreed, there is a definite lack of good moving APAC stuff out there. The biggest bummer though is that GTIA modes don't allow fine h-scrolling.

Gunstar Posted June 4, 2007 Share Posted June 4, 2007 (edited) http://atari.fandal.cz/detail.php?files_id=476 In the first part it shows 256 colours 3D with a "shine through-sphere" and in the 2nd part it shows a rotating cube with 16 colours and plays a 4 channel MOD in the background. This is even more impressive than Numen to me. There is still a big difference in some digitized music and a few low-res polygons with special effects, and an entire 3D world being manipulated, as in NUMEN, which though the demo is on a set course, the engine is full 360 degree 3D engine with height like DOOM. Numen demo also had some, IMHO, equally impressive, small interlude demos as 'Impossible but real.' Though your title statement 'Totally Underestimated' rings completely true. Of course I'm running these demos on an NTSC 1200XL with PAL OS and a PAL ANTIC. Mostly they(generally speaking) run fine, occasionally there are graphic glitches. IIRC, both these demos (NUMEN&Impossible) run glitch free. Another thing to keep in mind is that when these demos used APAC or similiar modes on NTSC machines the color is not nearly as vivid and often looks very washed out on certain, unmodified model 8-bits. I highly recommend the Super Video or Clearpic mods installed for the best color with these demos (with a TV/monitor with adjustable tint for best possible color). These demos also use the dual Pokey stereo upgrade too, IIRC, and many European demos do, so I recommend that upgrade as well. I've tried many of these demos, that use 3D and are dependant on speed for frame-rate, on NTSC 60Hz, and the ones that still ran, really gained in speed(FPS) noticably, it would be nice to see them "fixed" for NTSC. And also for some NTSC programmers to use these techniques in new demos. These graphics are so low res, that you don't lose any picture on the lower res NTSC screen. Especially since most of these demos are running in smaller windows or letterboxed. Edited June 4, 2007 by Gunstar Quote Link to comment Share on other sites More sharing options...
Jetboot Jack Posted June 4, 2007 Share Posted June 4, 2007 Quite nice I guess, but I don't see what's special, it's not realtime - just a bunch of pre-calc'd frames being set up and played back... sTeVE Quote Link to comment Share on other sites More sharing options...

+MrFish Posted June 4, 2007 Share Posted June 4, 2007 http://atari.fandal.cz/detail.php?files_id=476 This is even more impressive than Numen to me. I wasn't that impressed... and it certainly wasn't as entertaining as Numen. Quote Link to comment Share on other sites More sharing options...
