Scene closed collision

Post by blitzfan »

Hello.

I try to use Bullet for handling collisions in a small project, I started. :oops:

I come to define my objects, and detect collisions between them.
For cons, I'm facing a trouble in the static scenery, as the interior of a building for example.


I use this routine for detection:

Code: Select all

btVoronoiSimplexSolver sGjkSimplexSolver;
btGjkEpaPenetrationDepthSolver epaSolver;
btPointCollector gjkOutput; 

{
	btGjkPairDetector convexConvex((btConvexShape*)shape1, (btConvexShape*)shape2,&sGjkSimplexSolver,&epaSolver); 
	   
	btGjkPairDetector::ClosestPointInput input; 
	input.m_transformA = tr[0]; 
	input.m_transformB = tr[1]; 
	convexConvex.getClosestPoints(input, gjkOutput, 0); 
}
if (gjkOutput.m_hasResult && gjkOutput.m_distance<0) 
{ 
	ContactPoint = gjkOutput.m_pointInWorld;
	coldistance = gjkOutput.m_distance;
	NormalPoint = gjkOutput.m_normalOnBInWorld;
}
inside the buildings so I always detection.

As if, in fact, my building was considered a giant ConvexHull.
How is it possible to make detection in static world, including when they are closed?
I searched the forum, but confess it difficult to really find an answer.

Thank you in advance to those who take the time to read and answer.
