Trait implemented by shapes composed of multiple simpler shapes.

A composite shape is composed of several shapes. Typically, it is a convex decomposition of a concave shape.

Required Methods

fn nparts(&self) -> usize

The number of sub-shape in this composide sahpe.

fn map_part_at(
    &self,
    _: usize,
    _: &mut dyn FnMut(usize, &Isometry<N>, &dyn Shape<N>)
)

Applies a function to each sub-shape of this concave shape.

fn map_transformed_part_at(
    &self,
    _: usize,
    m: &Isometry<N>,
    _: &mut dyn FnMut(usize, &Isometry<N>, &dyn Shape<N>)
)

Applies a transformation matrix and a function to each sub-shape of this concave shape.

fn aabb_at(&self, i: usize) -> AABB<N>

Gets the AABB of the shape identified by the index i.

fn bvt(&self) -> &BVT<usize, AABB<N>>

Gets the acceleration structure of the concave shape.
