July 8, 2008

Started a cloth demo. I will be demonstrating several different ways to use cloths. So far I have a scene containing cloth as grass. Here's some pics:

Will show more pics as I progress. peace.

Created a scene where cloths simulate glass.

Very nice. I would start thinking of adding your scaling code in there so you can test the demo out on a min spec machine (little bit of grass) and a super rig (more grass, more glass), and maybe use the template demo that came with the free trial version to wrap your demo in, give yourself that edge before the deadline hits.

Finished version 1 for july 20.
Added a 3rd scene, where cloth resembles water and rigid bodies interact with it.
Added better scaling
more gfx
more sounds
added music
added help screens
added a menu
added a pause physics feature.
hmm... can't remember what else.

Here's a video:

best cloth demo i have seen! well done.

in the glass breaking section, do you think it would be possible that the glass stays fixed to the frame and just the centre parts breaks up?

also will the sources of the winning demos be published with the next dark physx update?

once again, well done i hope your efforts will be rewarded.

Actually i tried doing that, but was having trouble tearing the cloth where some pieces hanged.
While playing with the cloth tearing I noticed in the Dark Physics reference file, it says the value in function 'phy set cloth tear factor' can range from 0.0 to infinity. But I always get a runtime crash when the value is less than 1.1
I know wouldn't make much sense being less than 1, but it's a little typo I've noticed along the way.

I'm still going to play around with the idea, might be another way to achieve the same effect.

Thanks for the kind words everyone.

Yeah that'd definitely be worth experimenting with more.
All up though, that is a very impressive demo, and such creative use of cloth. Good going

Whoo, I won a beta prize
I've had requests for the demo, so if you want it, here it is:

Should note that I used the Trial version of Dark Physics, which expired on Sept 30. So I don't know if it will work anymore... I have included the source, so I'm thinking you should be able to build if you have Dark Physics. Anyway, cheers

that`s a good demo, well done
