Hi,

I'm confused by the emptiness of the Tutorial section... 'Due to lack of resources, the tutorials section of this website has been removed' doesn't really explain much! Human resources, network resources, or something else?

As someone who's new to Processing (but not to programming), I can see that it's not going to be all that hard to pick up - but it would still be an awful lot easier with a few simple paragraphs (isn't that all that's really needed?) on How To Get Started!

Feeling my way around...

- Oo.

that means casey and i are maxed out, and casey in particular doesn't have time to properly maintain the tutorials section.

and you've seen the "how do i get started" section of the faq, right?
http://processing.org/faq/index.html#start
it's not tutorial but it at least provides some pointers to the basics.

Fair enough!

I did see the 'How do I get started' bit, I think, thanks - or at least figured out that much before I posted this - I was just hoping for a bit that would tell me the first few things I would need to know in order to do anything much.

Anyway, I was just impatient to get started, having realised how cool this thing is and wanting to start making things straight away. The lack of a general tutorial on how to start using the language hasn't held me up for long, anyway - here's my first processing sketch! It's a bit slow, and too dark really, but I'm delighted all the same...

Thanks for all your work

- Oo.

p.s. Here's my second processing sketch, based on the first, brighter, faster, simpler. Wooh!

Runs quite slowly here (3GHz), you might want to try the P3D graphics mode in your call to size(), or if you're adventurous, accessing the pixel buffer directly with load/updatePixels.  I tried editing the source, but it seems to be different from what you posted.

Puzzled by the different source, it shouldn't be

You're right, using P3D does seem to help quite a lot, although I can't find any documentation of it (!) so I don't know why... (it's not like I'm doing anything genuinely 3D, so I wouldn't've expected any improvement...!)

Anyway, these are both running way faster than they were, thanks to this and various lookup-table-based optimisations:
http://mimeomai.f2s.com/applet/zooby2.htm (not really the same as what I posted before at all, but related)
and http://mimeomai.f2s.com/applet/yinyo4.htm

Cheers!

P3D is documented with the size() command, since that's where you use it:
http://processing.org/reference/size_.html

the fact that it's faster than the default renderer for some things (mostly dealing with pixels) is an issue in the beta release, but will be fixed someday.

Thanks fry... Sorry, I was unclear - 'can't find any documentation of it' was a bit of an exaggeration, in that I had found http://processing.org/reference/size_.html - I was just thinking I must be missing something that would tell me more than that it's a 'Fast 3D renderer for the web' - like what differences it makes besides (presumably) allowing us to use 3D primitives... for example, does it have any disadvantages, or would we do well to just use it for everything?

P3D sacrifices quality for speed, so images are likely to not look as good. it also doesn't allow strokeWeight() or smooth().

someday this will all be documented. but for now, bask in the glory that is using beta software.
