Webcam and papervision3d

This night I saw this

So I wanted to try this in papervision3d. Well it is possible but there are some depth problems.

Flint is now ready for papervision3d

September 17th, 2008 • flash, flint, general, hot, input, papervision3d

Wohoo! Yeah! Awesome! I just read that flint particle system now has the promised pv3d renderer. I’ll test it asap but at first I should enjoy the last sun rays here.

check it out:

you should also read about a bug in papervision3d in the earlier posts of the flint blog. Otherwise it might not work

Touchscreens aren’t completly useless

Great idea. Combining a “normal” screen and a webcam with a tracking algorithm might be fun aswell.

Here is an opml file of my current google-reader-subscriptions (round about 50 rss feeds). Most of them are written in english – only a few are german. Maybe you have a good tip for me.

pv3d + 2d objects

September 16th, 2008 • flash, general, hot

On http://www.allflashwebsite.com/ are two very interesting posts about combining 2d and 3d in flash. Post one shows how to setup the camera but the real cool thing is the post two with a non static camera.

enjoy!

AS3 – a good way to preload

September 16th, 2008 • flash, general

This videotutorial is really easy and shows a great way to preload a swf. Usually I used the two – frame method but this causes trouble (also explained in the tutorial). enjoy!

My curtain, but not my credits

September 12th, 2008 • 2 comments demo, flash, general, lab, papervision3d, wow

The real tricky coding was done by http://www.clublime.com. But his demo is down for some reason. So I just changed his cloth idea a little to get a really nasty green curtain.

demo and source are here:
http://experiments.alexmil.de/pv3d-curtain/

The idea isn’t verry so tricky at all. The plane is analysed and on everey “corner” (just look on it with applied wireframe material) a “ball” with physics is added. Theses objects will not be rendered. Balls are “wired up” with constraints. When the physics kick in the balls move. Their new position (x,y,z) is also the position of the plane vertices. Hm doesn’t sound simple at all… but it really is. Major problem is – as i explained earlier – the performance on planes with a huge amount of vertices.

Physics and Flash – my summary

September 5th, 2008 • flash, general, hot, papervision3d, wow

The last days i worked with the wow-engine and papervision3d. I tried to simulate a capet that opens with a specific behaviour.

Sorry I can not yet post the source cause it’s part of a commercial work. But I will – maybe – someday :-)

So here is my subjective view what you can achieve with that setup, and what not.

You can:

• simulate falling, bounching and movement of non complex objects
• create the illusion of wind
• create the illusionof elastic material
• using a tweener – create greate almost organic effects

so thats the good thing. but there are also some bad things. don’t get me wrong i’m happy that pv3d and wow are ther for free. I love it. But there are some things you can not yet achieve with it.

You can not

• simulate complex material with a lot of vertices (cpu!!)
• create a really realistic material (allways behaves kind of odd)

Wow is very cool! I love it and I will use it again for another demo. Combining phyiscs and an audioanalyser might be fun.
