I'm sure I remember a pd racing "game" which I had on a coverdisk (possibly AUI?) Which allowed you to use your own iff files and drive on them. Can't remember how much actual gameplay there was but it was when I had my A500+

But I won't reveal any further details until I've had the time to test it out for myself |

Interesting project, because it‘s kind of never really been done before.
If I‘d not being so busy with Inviyya I‘d loved to have a shoot at it myself.. |

In danger of suggesting something completely irrelevant, isn't the floor of Unreal's 3d sections eligible for this? It's a bit restricted in terms of horizontal+vertical movement, but it can move and zoom at the same time at will, so....

Im am very sure that these floors are made with some tricks, and that you wouldn't been able to freely navigate in them, e.g. drive backwards or doing 90 degree turns...

Gasega has also coded the Md wolf3D version . [ Show youtube player ] And don't forget the Md has a chunky display,it help a lot for that kind of effects . If you want to know how he did do this, you can read the sega-16 tread : http://www.sega-16.com/forum/showthr...for-Genesis-MD Last edited by touko; 16 March 2018 at 18:53. |

No idea whatsoever, I just noticed that you could move at both x and y axis at will and the floor perspective would respond to it, while zooming, and thought that it looked like a good candidate.

Tadam! Time for my traditional yearly super-long post with plenty of quotes.

I have not looked at how the effect is implemented but I would wager it is not as flexible. Quote:
When I read the sega-16.com thread where gasega68k discussed the technique he implemented it wass clear that he is not using raster effects but real per-line perspective transform. As DanScott mentioned, that is essentially a rotozoom with different parameters per line. Of course this is *much* sped up on the MegaDrive/Genesis by the fact that the pixels of its tiles are in chunky format and that its CPU runs 1/3rd faster than the A500's (12 MHz vs 8-ish MHz). Quote:
Moreover Copper chunky is compatible with any lores graphic mode with up to four bitplanes so 16 colors BOBs can be drawn on top of the floor, in addition to sprites. I would wager that this is what Virtua Karting does on the A1200 with the advantage of a faster Copper which allows 4 pixels Copper chunky. Quote:

Is your wolf3d-demo published already? This said, although I think some form of C2P can be used, I doubt that this would allow this effect to run in 16 colors on a non accelerated ECS machine as the C2P pass will consume a lot of the available cycles. Since this is floor-only rendering technique I would rather try using the Copper and/or a limited number of bitplanes rather than to do a full C2P which I think is not efficient enough on 68000 kittens if you want to run an actual game on top of displaying a nice floor. But it is good that several are thinking about it. The more kittens, the better. |

@ReadOnlyCat
Isn't MegaDrive using a 7.6Mhz 68k? I think it's MegaCD that uses a 12.5Mhz one. @saimon69 Yes, isn't it? Many many stuff thrown around and at a very good pace as well! Definitely a good engine for an afterburner/galaxy force game! |
