}Expand description
Traits of convex shapes representable by a support mapping function.
Parameters:
- V - type of the support mapping direction argument and of the returned point.
Required Methods§
sourcefn support_point(&self, transform: &Isometry<N>, dir: &Vector<N>) -> Point<N>
fn support_point(&self, transform: &Isometry<N>, dir: &Vector<N>) -> Point<N>
Evaluates the support function of the object.
A support function is a function associating a vector to the shape point which maximizes their dot product.
