}

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

fn support_point(
    &self,
    transform: &Isometry<N, U2, Unit<Complex<N>>>,
    dir: &Matrix<N, U2, U1, <DefaultAllocator as Allocator<N, U2, U1>>::Buffer>
) -> Point<N, U2>

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.

Provided methods

fn support_point_toward(
    &self,

    dir: &Unit<Matrix<N, U2, U1, <DefaultAllocator as Allocator<N, U2, U1>>::Buffer>>
) -> Point<N, U2>

Same as self.support_point except that dir is normalized.
