Since there hasn't been anything in here in ages, i thought id just add something quick.
Been messing with mode 7 over the past 2 weeks, mainly during lunch at work *hides*.
Very rough and not awesomely accurate (uses lots of shortcuts
), but its kind of the effect:
Its only a side project for kicks, i don't think anything will become of it. Just in case anyone is paying these forums any attention

That is really cool o.o I need to better figure this stuff out o.o Do you read from a bitmap to figure out which regions should be darkened? In other words, are you pretty much viewing a bitmap from ground level, so to speak?

Thats kind of the idea. You can read from a bitmap or in this case a tilemap to save space.
Basically the idea is for each line you draw you apply a scaling factor. To apply rotations its kind of like a line routine that steps through your image data each line using the magic of trig.
Im assuming anyone who has dabbled in calc mode7 has got their inspiration from this:

Very good resource

It looks a lot better with rough grayscale:
calc84manic was kind enough to discuss how gs is implemented in his fzero engine, its the same idea here however it is not in synch timing wise its still a good start. Interestingly the way the rest of the engine works is vastly different. Its probably one of the most fascinating things about coding, there are lots of ways to achieve the same goal

It looks very smooth and fast, tr1p1ea - great work!

Yeah, fast o.o Are you using 15MHz, as well?

Yeah that screenie is at 15MHz, seems to work pretty well at that fortunate cpu speed

Def. looks better with gray. Even if nothing comes of this it's a cool distraction nonetheless.

not being in synch doesn't seem to matter a whole lot with that much motion, too, so i don't think it's something you need to worry too much about.

Wow, how'd i miss this? It looks great! I really am awful at math and have long since forgotten how all that trig stuff works/what it does, i really should revisit that stuff...

Mario Kart! Ha just kidding, i'm with chickendude...once I finished college all that stuff got filed away somewhere. All those coding going on is starting to make me feel left out ha

Well ive ported the basics over to the 84C, with some modification of course.
At this stage i havent optimised so its a little slow. Currently the draw area is 128x60 in 160 mode:
I havent tested on hardware, but think that it wont run this fast (think the screenie delays are borked).

That looks really neat, tr1p1ea - did you get the opportunity to try it on hardware to see how well it performs?

Thanks Ben!

That is a video of a rough test on hardware, the speed is ok but the accuracy has improved since that was taken.
