in fact, as an example, i say 3 bits luminance, a smarter move will have been to half the R/G or B according to 1 of the 3 extra bit.
It will be an RGB EHB mode.
If you have white FFF and use the 6 plane in EHB, your output color is a grey 777
So with the RGB EHB mode, you have a white base color FFF, if you put a 1 in the first extra bit plane, you've got 7FF, in the second, F7F and in all three extra planes 777.
I think it would be more useful than 3 level of brightness of the same tone.

But it is not the place, and it's 25 years too late :-D

Running realtime on a 50mhz cpu from 1990 and busspeed from 1985
this is truelly a masterpiece.

It's not a demo, it's a scifi movie !

Yes, it's quite nice and will merit the comparaison with freespace
EXTERNAL LINK  EXTERNAL LINK  I particulary like the flat shaded feel look of the effects like the hyperspace exit

But it was quite slow outside the A4000 060 according to this page
EXTERNAL LINK  A1200 040/25/40 
AGA HQ 6fps/10fps LQ 10fps/15fps
RTG HQ 6fps/12fps LQ 10fps/16fps
A4000 060/50 CGX 
AGA HQ 22fps LQ 25fps
RTG HQ 24fps LQ 30fps

But the good news is that if we can contact this guys and told them about natami, we could have an enhanced version with voodoo class graphics

I will give you that it may be the best 3D engine in an interactive demo.  It was a real disappointment when we only got the demo and no actual game.

That would be grand! I was just going to suggest a clone of Wing Commander for the launch of NatAmi... Lambda Sector would work perfectly!

So what? It's still realtime! :) I didn't say "game"! ;D

BTW, the graphician involved appeared on amiga.org recently, but the coders behind the project left Amiga-related activities long ago (some of them are the ones behind Lapsuus too)

I didn't personally find it as impressive as the TBL demos (or even Lapssus) which show animated figures for example.  Also it doesn't really have many effects.  I thought it strange that you championed it as "hands down best" when the others seemed to be doing so much more and to better creative effect.

Or maybe I'm just still mad at it for never being finished.  I had all of the previous versions starting with just the ship.

For me best 3D would have to have a lighting model, texture mapped polys, some type of surface effect (eg. bump or env map) and attempt a recognisable shape (no rings or cubes)

Things that impress beyond that are having a fully enclosed or panoramic environment (even if just a skybox or stars), animated figures (smooth bending figures being more impressive than robots), and finally post processing type effects such as screen bloom or depth of field.

I believe someone mentioned a Doom style FPS as having the best 3D.

I recall something about them moving on to create Futuremark and so on.

Well, none of TBL demos or Lapsuus can't be considered true realtime (read: "interactive"). That said, I agree that both TBL prods and Lapsuus are masterpieces (most of them at least), but try to ask the coders to make an interactive version of them and just listen to what they have to say... ;)
(Lighting, character animation...almost everything is precalculated there. That's why I made the distinction between "interactive" and "demoscene release" in my first post)

That is a very good point.  I've been taking part in a similar discussion on CGTalk about real time engines versus renderers.  There is always disagreement over what is real time and what is rendered when you can precalculate almost everything and still have it be interactive.  If I can only move the camera I'm still interacting, even when the entire sequence is baked (such as in the famous train ride sequence that opens Half Life).

I get 50-60 fps on average with the newest Lambda demo on 68060 + RTG. Best fps I saw were in the upper 70s and lowest in the mid 30s. Very fluid with no perceivable slow down at 320x200 (default). It's much faster than Quake at this resolution.

Tastes differ! ;)
Relic is a great space-opera and there are loads of neat coding tricks into it. But I don't really feel like watching it more than once a year! :)
"When we ride", on the other hand, has no real plot and it's more of a tech-demo, so I find it pleasant to watch it more than once a year! ;D
(not to mention that coding-wise there's plenty of coding wizardry in there (1x1 perspective-corrected texturing with a very good framerate)
But I see your point. In the end, we must consider ourselves lucky, we can enjoy so many different and high quality releases on Amiga!

Now I can't wait to see how the first generation of Natami demos will look like!!! :D

Imagine it with the capabilities of the NatAmi...

I did not saw yet the others Demos

It's a great demo for an "Amiga dream" ... And may become true on Natami. :)
