Orientation of shape in convexSweepTest

[shogun]

Hallo,

I'm doing something like

Code: Select all

btCollisionWorld::ClosestConvexResultCallback cb(rayFrom, rayTo);
btConvexShape *cylinderShape = new btCylinderShape(btVector3(r, 0.005f, r));
m_dynamicsWorld->convexSweepTest(cylinderShape, from, to, cb);

The problem is that the cylinder I use is always axis aligned. But often my "to" vector points to the right or any other direction other than up or down - so this axis alignment becomes a problem, because the callback's m_closestHitFraction is wrong now (at least wrong for me).
Is there any workaround for this, or another solution?

Regards,
shogun

I my problem unsovlable, or just not important?

btCylinderShapes are always axis aligned.
You could get them transformed/rotated using a btCompoundShape. See btCompoundShape::addChildShape.

Cheers.
