the eidolon - 3d engine in detail

well, this production is not really scene one but i always wondered: how could that be possible that such an oldie is so fast being realtime? what kind of calculations are made and is it 3d at all?

neat but it's not as complex as eidolon, though :)

Christopher Jam did a quite fast rendition of a 3D-engine, using the map from Driller in Effluvium. Should be considerably faster than the original implementation.

Considerably faster yes, but still crawling dead slow. I think faster is the wrong term, less dead slow would be more appropriate (don't misunderstand me now, I personally like Effluvium very much!)

It'll never be "quite fast" on a C64, but maybe "not THAT slow"! :)

I've heard rumours about something that I would actually describe as "rather fast". :)

Quoting jammer
ok, he did a speedup for dtv and i guess took advantage of faster clock.

This is a popular misunderstanding of the DTV. The DTV has the same clock as the C64, but in my release I use the skip, burst and disable-badline feature.

as i've read out, it's equipped with 32 mhz cpu emulating all c-64 chips at their original clock speeds thus i apologize for my mistake ;)

What's the best place to read about it in comprehensive way? Also is there some place where you can buy modded DTV? Modding it myself is out of the question.

@jammer : look in this way, you are right. Looking from the programmers point of view, it has about 1Mhz. You don't need to apologize for this ...

Modded Devices - no idea ...
