Image mapping : Peer review needed

It's soon the week-end.

The sky is blue and the grass is green on Oric Planet.

Nice! (and have a great weekend)

[Symoon]

Looking great!
Is this already ASM-optimised, or is there potential room for speed improvement?

[iss]

Congrats! And I'll second @Symoon?

[Dbug]

Even at the same speed, not erasing before redrawing would improve the quality perception quite a lot: Just draw each column over the current screen content, and just continue in green or blue above and below

With colors !
Impressive !

[Chema]

Incredible. Awesome.

Thank you. I'm going to take profits of the blue sky

There remain some room for speed improvement but they are starting to be small. I need to get the code reviewed by Dbug. He usually find some unespected source of gain.

Just draw each column over the current screen content, and just continue in green or blue above and below

That's a very very good idea !! Once again you give me the key to find some smart enhancement. Thank you

Thank you kenneth and Chema. I'm glad to impress you

Someone tells me that this file doesn't work because of a header format error.

Are you experiencing the same issue ?

Nota: The collision detection is a bit "severe" so we can't move when we get too closed from walls.

[jbperin]

It works !!

Jede tested on real Hardware !



Thank you so much Jede !!

Very, very nice to see this proceeding at a rapid clip. Yes, seems like its time for a code review .. certainly looks performant, but I bet DBug finds some tricks ..

[jbperin]

, but I bet DBug finds some tricks ..

Correct.

He found some veey nice ideas of optimisation. and enhancement . I'm coding some of them.

I think there might be some.good surprise soon .

Stay tuned.

[jbperin]

I took into account numerous remarks from Dbug about optimisation and from Adrian Brown and Jonas S Karlsson for redrawing strategy.

Here's what it looks like now:

And thanks to the work of Hialmar you can even ;..

>>> PLAY IT ONLINE <<<

You're going to be redirected to a page where you have to click on the raycast.tap link.
Then it's going to load the demo into the javascript oricutron (a bit slowly because it is hosted at home).

- Up and Down Arrow to go forward / backward
- Left and Rght Arrow to turn
- W+X to shift

PS: Dbug still has some very smart ideas on how to speed up the rendering ... but the problem is that he has more good ideas than I have courage.

[Symoon]

Amazing!
That's a great improvement.

[ibisum]

Wow, its brilliant - very playable!
