That would however be the fastest and cheapest way to do it, and i did check almost frame by frame the video if was doing any perspective change: keeping an eye to the central set of tiles their perspective does not bend lightly to left or right as expected; instead only the center of the tunnel moves. The trick is not too visible due to fade out

You're absolutely correct, the perspective doesn't change (at least not in the video).

[Tigerskunk]

So if the perspective doesn't change in this video, I really need to get my eyes or brain checked..

What a great effect, anyway..

Time to get your eyes checked

Of course it's easier to spot when having coded n+1 tunnel effects in the past.

That we can agree on

[Tigerskunk]

Wow, the mind can really play tricks on one...

[Cyprian]

anyway, that's just well done
would be cool to have a port for /|\ TT/Falcon

[Solo Kazuki]

Everyone who are "so sure" i recommend translate this answer.

[Cyprian]

@Solo Kazuki, I saw that before.
That statament doesn't exclude technics mentioned in this thread

---EDIT---
this one is more interesting:

I've mentioned this before and it automatically exclude most of mentioned later ideas...

He's lying if he claims NOTHING is prerendered. But I'm assuming that's not what he actually said.

[Cyprian]

@Solo, for me Kefir's statement sounds as a pure sarcasm

[Solo Kazuki]

For me sarcasm is just with emulation of cores, that's why he use later (mentioned in comment #47) "draw" word about tunnel.

He's still drawing the tunnel, even if it is on top of a prerendered animation.

This.


@Solo Kazuki:
You are probably misunderstanding our comments and you are definitely not advertising Kefir and his game well.
I don't think I've read anywhere that the game teaser is not a joy for the eyes or that Kefir's work is not exceptional in this.

Only assumptions have been made about how it can be accomplished. Nothing less and nothing more, I don't see anything bad or personal in this.
Which is only a favor to Kefir, because just talking about it increases its visibility.
If I'm not wrong this is the Coders section.

I seem to understand that Kefir himself has every intention of explaining in detail in the future how the engine works (so removing from the carpet what is obviously not possible achieving on the Amiga with those technical specifications).

Let's analyze Kefir's sentence (from google translate, so I hope it is more or less exact):

"The way I draw the tunnel has not been used so far by anyone"
which is likely to be

"so I can immodestly say that I came up with something new on the Amiga."
which is a bit pompous but is absolutely likely to be

"The effect is great"
very true and nobody doubted it

"so for another programmer it's a challenge to guess how it's done."
and is what coders are talking about here

I do not see written anywhere that the various assumptions made are wrong, maybe only some are right, others go close, others are out of the way.
And nowhere do I read that the game is full real time.

There will certainly be parts in real time (it's not an animation, the game must work and all the various effects on the blocks must necessarily be in real time ).

But there are many points in the video, coders who had done that kind of effects know it, that make it clear that much gfx is pre-rendered and some compromises accepted.

Cheers.

[Cyprian]

sounds reasonable

I'm beginning to think that's I'm the one who is misunderstood. Excuse me, please show me where i accuse someone for blaming anything? It never happened!

I'm just talking from beginning that pre-rendering stuff was told on PPA before.

And that's what i mean from beginning. Some people are sure that they know how it works. And i try to ask "then why something not fit", e.g. many optional turns of tunnel. How many combination should be prerendered? Just one makes two optional prerenders, and if there are more than three (visible on linked video) at once?

If you're speaking of the rotations, then you'd only need two additional sequences (one for rotating clockwise and another counterclockwise)

[Solo Kazuki]

And this is just one rotation... but again, what if it's three of them? You have in this case six (!) prerendered sequences. And what about more? In this way you meet out of memory sooner or later, isn't?

You can check with paint program like GIMP. Pause video in two places were you think perspective is different. Make screenshot each time. Put screenshots in two layers in paint program and make top one 50 % transparent. Move top layer around until center of tunnels match up.

You of course use the same sequence for every single rotation (it rotates the width of one block) and just adjust the overlaying LUT-tunnel to match.
