Hi, I tried to create a cone which is pickable. If I use Cone(1.8f, 10.0f) and setAppearance(appearance). The color of cone is correct. But I was not able to set Primitive.ENABLED_GEOMETRY_PICKING since setPrimitiveFlags() is depreciated. If I use Cone(1.8f, 10.0f, Primitive.ENABLED_GEOMETRY_PICKING, appearance), the color of cone is not correct since I got a white cone. The document says that if appearance is null, the color of cone is white. I am sure that my appearance is not null. What happens to this cone constructor? When I use Cylinder(1.8f, 10.0f, Primitive.ENABLED_GEOMETRY_PICKING, appearance), the same thing happens. My question is how to make a cone and cylinder pickable? Any idea on this? Thank you very much.
