try to simulate soft body, bind with ogre

[foolegg]

a small test

this patch and ball is a ogre format mesh, create in blender

and I'm trying convert this ball to a convexhull, testing...

[foolegg]

e....

Code: Select all

btConvexHullShape::btConvexHullShape( const btScalar * points = 0, int numPoints = 0, int stride = sizeof(btVector3) )

this constructor optionally takes in a pointer to points. 
Each point is assumed to be 3 consecutive btScalar (x,y,z), the striding defines the number of bytes between each point, in memory. It is easier to not pass any points in the constructor, and just add one point at a time, using addPoint. btConvexHullShape make an internal copy of the points. 

According to my understanding, the *ponit is a array like this format:

Code: Select all

{ x0, y0, z0, x1, y1, z1, x2, y2, z2 ........ }

just like vertices array

and numPoints is the count of vertics

it's correct?

yes, I deal with convexhull problem, but encounter another...

like this

snapshot11.png

the softbody pass the sphere after collision.

then，I scale the sphere, I enlarge this sphere 5% with

Code: Select all

bshape->setLocalScaling(btVector3)

it well

what should I do to deal with this problem? thx for any information.

this is src

soft_dev.tar.gz

in line 329

Code: Select all

    btScalar s = 2.0;
    bshape->setLocalScaling(btVector3(s,s,s));

s = 2.0 work well
s = 1.9 will with trouble

ps: there is some chinese charact in src commit, maybe you system cannot not display it, do not worry about it...

I record this video demo, to show the problem
