Just put together my current verlet physics system into a small zip. get it here:

www.freewebs.com/botbuilder/downloads.htm

Only 16K! Although if my site doesn't work, I probably ran out of bandwidth, as I only got 100Mb.

E1 and E2 are just basic physics example
E3 is a cube colliding with mathamatical spheres
E4 sux. it's a flat cloth colliding with a flat ground.
E5 has potential. change the second parameter of "vcloth" to 6
E8 is a cool snake demo. yep. 100 verlets runnin fast. works with 1000 if you have a fast machine.

I shoulda included the cloth on sphere demo but I was lazy. Maybe next demo.

very nice man very nice indeed :D

thank you. I think I'll compile some cooler examples.... post um up on the board since their tiny.

That cloth example is cool

here's a much better cloth example. please note that this is real time physics, and when you have a slow computer, or alot of stuff runing, the results are unsatisfactory. sometimes the cloth actually goes through the sphere.

Very nice stuff :)

The main thing stopping people using this stuff is the ease of use and cage building.

an editor would be nice for cage building...

i do hope u finish this, as this will definetly be one of the best stuff happening for blitz

Yeah. Once I get all my stuff working properly, perhaps integration into singularity, I'll Definitly work on a cage editer. I remember one guy had somthing kinda like a cage editer. Only worked for objects that are cylindrical around the x/z axis though. Hmm. Actually I don't see to much for stopping me from making one now. I would like to make it look pretty with say, BlitzUI or somthing.
