Additional Inherited Members

- Protected Attributes inherited from coal::ShapeBase
Scalar m_swept_sphere_radius {0}
 Radius of the sphere swept around the shape. Default value is 0. Note: this property differs from inflated method of certain derived classes (e.g. Box, Sphere, Ellipsoid, Capsule, Cone, Cylinder) in the sense that inflated returns a new shape which can be inflated but also deflated. Also, an inflated shape is not rounded. It simply has a different size. Sweeping a shape with a sphere is a different operation (a Minkowski sum), which rounds the sharp corners of a shape. The swept sphere radius is a property of the shape itself and can be manually updated between collision checks. More...
