thanks

Re: iterator tutorial

here's this. bottom right you have the option to download a high resolution. 1024x768, 20.41MB.

The direct link is this: http://vimeo.com/download/video:43728151?v=1&e=1238434492&h=4f5a34b5c1b0...

Re: iterator tutorial

I'm going to have to bump this as the video link doesn't seem to work - Any chance of the related files to the tutorials?

Many thanks

Am I doing something wrong here? - I know the thread on the vimeo link suggest downloading the original high res version, but I can only see a 504x380 flash video version to download - I can't see the detail of the math expression etc - Are the quartz files available as a reference?

many thanks

Re: iterator tutorial

You are doing absolutely nothing wrong themuteboy and at the time of providing the link to vimeo, that site was making available a high quality video for registered members - even non premium members.

I see from my vimeo video URLs that they do still make available for download whatever HD / original QuickTime versions I've made available. When I picked up on this thread a couple of days ago, there was a QT high quality version to download of the Iterator tutorial.

Now as you found,themuteboy, it is FLV for that particular tutorial and it would seem, other tutorial videos besides on cwright's vimeo page.

FLV can give excellent results, but it does have a quality trade off regards video quality / video size. The smaller the FLV file size, the longer that small file size, the lower the quality of its video fidelity .

Re: iterator tutorial

i just made a tutorial on multi-touch and how to fake water as well as deal with structures etc.. on my web site. http://pixel8r.info there are some good iteration examples in the compositions section. it seems a iteration tutorial is needed possibly. might make one don't know i couldn't view any of those links. im not exactly sure how to articulate an iterator. I will think of something fairly easy to iterate.

I believe the term comes from the C++ vector library or vector standard template library. which is really a dynamic array but with some easier features to add or push its called im not good with the vector library to tell you the truth i had a real hard time iterating through multi diminutional structs of arrays with the vector library. basically in the vector library you are doing what a for loop with index does by iterating through indexs of your arrays.

In QC it acts like a for loop and a copier. It gives you your index position current index length of iterations as well as makes multiple iterations of what ever is inside of it so you can offset the current position with some math on lets say the x axis of a sprite and it will copy that sprite each iteration on the x axis by the amount of your expression.

I to was a bit scared of the iterator at first just because of the aforementioned vector library giving me headaches but if you just want to think of it as a copier rather than for loop.

Re: iterator tutorial

I know this is an old thread, but,.. the tutorial video problem was never resolved (the part where the formula is entered is unreadable)- I for one would really appreciate a hires version / or a new tutorial explaining iterators. Thanks to all you kineme folk for sharing your fantastic work.

Re: iterator tutorial

A 3rd party [cybero] Iterator tutorial is on it's way.

BTW - George: - didn't you do such a tutorial?

Might be mistaken, as I couldn't find a listed URL pertaining via Google and soon grew fatigued with browsing through your growing vimeo collection for just this one, probably non-existent item **:-)]

Re: iterator tutorial

The formula are: 'a * 2 - 1' on the first one... 'cos(360 * a + 90 * b)' on the second one. Iterator Position goes to 'a' and Patch Time goes to 'b'....

Hope that helps...

Re: iterator tutorial

It seems like I have... I wonder if I did one on my website? It's most likely that I addressed some smaller aspect of iteration, than a broad explanation...

I'll try to group any of my videos that border on instructional in one library on Vimeo, to make it easier.

I'm pretty sure Chris's is the big iterator tutorial (I was just thinking the other day about how I've never seen it.... sorry Chris!).

Re: iterator tutorial

Thanks for the formula Joris -
George - love to see some tutorials from you (especially a channel) I find your QC + music comps very inspiring

I'm starting to introduce QC to my high school multimedia students - waiting to grab a copy of 'the book' by momo and shakinda - THX heaps - let me know if you're ever in Australia - my shout Ben
