I got bored last night and felt like learning something. Read a chapter in the calc book, that was boring. So I read a chapter from the physics book, and came out with this.

Flag Demo

Demo is 1.5mb, download it from that page. There's also a screenshot on that page.

Awesome!!! I wish you'll be bored permanently because each time you're bored you give us some great pieces of coding. . Any chance to see the source code?

Sorry for my English...

Phaelax, nice work.

How did you do it?
I would guess you went something along the lines of;
You 'pin' two verticies of the mesh into one spot, you then have a 'direction' for wind, which effects each triangle differently depending on it's orientation to the wind, its omega rotation, its size, and the 'pull' on it by adjoining trianlges.
You then use this calculated change to rotate/reposition verts..?

Jess.

That looks a lot like one of the final few chapters from "Physics For Game Developers". .... Still very cool though. I haven't actually read any of that book since I bought it (while on holiday in NY).


If I can't eat it, drink it , **** it or fire it, I'm not interested

good eye adr.
it uses springs and dampers. mesh was created with memblocks just like I used for making matrices. Used Dmitrys plugin for the vertex manipulating

I forgot to mention, A and Z change the wind speed and spacebar releases the flag from the pole.

May I add... That Is One ELASTIC Flag... It could expand to more than 3 times its original size.



Cool demo by the way!
