I have a project idea that I need to create a sphere and use it's interior for collision detection. I can only find information in Farseer that creates a filled circle. Is there a way to do it with CircleShape or do I need to create the sphere using vertices? Or if anyone knows of another physics engine that can do this. Thanks
You could use an chain shape which allows for 2 sided collision for the circle, but as far I know there is not a hollowed circle object.
