Object is not visible in CollisionInterfaceDemo

[WGutsche]

Hallo,

I have downloaded bullett-2.66 and making my first steps with appCollisionInterfaceDemo in msvc-6.
In initPhysics() I changed the type of objects[1] from btBoxShape to btSphereShape.
//btBoxShape* boxB = new btBoxShape(btVector3(0.5,0.5,0.5));
btSphereShape* boxB = new btSphereShape(0.5);
If I run the application, I see the points of collision, but I dont see the object itselfe.
I get the same result if I use btCylinderShape or btConeShape.

I thing, I make something wrong.
