Wolfenstein 3D IS technically possible on stock A500 shocker!

[Linde]

Sacrifices had to be made, and most importantly, bloodshot requires more mappable memory than a stock A500 can provide. Here's an interview with the programmer: http://www.segacollection.com/specials/jimbinterview.htm. It is far from Wolfenstein 3D!

Was it running on that hardware or an OCS machine with a faster CPU?

It runs full speed on a stock 1200, and I wouldn't be surprised if it ran on a 500 as well.

The thing people are missing about demos is that they are not games; for example, Superoriginal doesn't have a working game engine with sprites, sprite occlusion, AI, free movement etc and is undoubtedly heavily optimized narrowly for exactly the kind of scene that is displayed, most likely with a lot of memory taxing precalculations. Still very impressive, but far from a game.

... and what people seem to be forgetting about other 3D games for the Amiga is that, in the end, they are not Wolfenstein 3D. There's really only one way to conclusively prove that an A500 is capable of playing Wolfenstein 3D at an acceptable framerate...

Planar is good for certain things.  Fades to grey.  HAM.  For a planar chip to be efficient, it would need to be triple-cored...so that each core could handle one of the three primary colors.  That is the only way to get the speed out of it.

BTW, does someone have an example of HAM c2p? Sounds kind of processor intense but it would be cool

[Linde]

But doable in a smaller window, 2x1 pixels, lower framerate (not for action FPSes, but fine for RPGs), etc. If a 4MHz Z80 can render a semblance of Wolf3D graphics (http://www.youtube.com/watch?v=COH55Uj53TY) then an A500 can as well.

I definitely agree with you, but I just have to point out that your video example is not entirely real time - it's still far from from an interactive engine in that distances and texture coordinates are precalculated, as is explained in the video description. I'm sure you know this, but just before anyone else goes into a frenzy
