Implementations

impl TriMesh

pub fn bounding_sphere(&self, pos: &Isometry<Real>) -> BoundingSphere

Computes the world-space bounding sphere of this triangle mesh, transformed by pos.

pub fn local_bounding_sphere(&self) -> BoundingSphere

Computes the local-space bounding sphere of this triangle mesh.

impl TriMesh

pub fn canonical_split( &self, axis: usize, bias: Real, epsilon: Real ) -> SplitResult<Self>

Splits this TriMesh along the given canonical axis.

This will split the Aabb by a plane with a normal with it’s axis-th component set to 1. The splitting plane is shifted wrt. the origin by the bias (i.e. it passes through the point equal to normal * bias).

Result

Returns the result of the split. The first mesh returned is the piece lying on the negative half-space delimited by the splitting plane. The second mesh returned is the piece lying on the positive half-space delimited by the splitting plane.

pub fn split( &self, position: &Isometry<Real>, axis: &UnitVector<Real>, bias: Real, epsilon: Real ) -> SplitResult<Self>

Splits this mesh, transformed by position by a plane identified by its normal local_axis and the bias (i.e. the plane passes through the point equal to normal * bias).

pub fn local_split( &self, local_axis: &UnitVector<Real>, bias: Real, epsilon: Real ) -> SplitResult<Self>

Splits this mesh by a plane identified by its normal local_axis and the bias (i.e. the plane passes through the point equal to normal * bias).

pub fn canonical_intersection_with_plane( &self, axis: usize, bias: Real, epsilon: Real ) -> IntersectResult<Polyline>

Computes the intersection Polylines between this mesh and the plane identified by the given canonical axis.

This will intersect the mesh by a plane with a normal with it’s axis-th component set to 1. The splitting plane is shifted wrt. the origin by the bias (i.e. it passes through the point equal to normal * bias).

Note that the resultant polyline may have multiple connected components

pub fn intersection_with_plane( &self, position: &Isometry<Real>, axis: &UnitVector<Real>, bias: Real, epsilon: Real ) -> IntersectResult<Polyline>

Computes the intersection Polylines between this mesh, transformed by position, and a plane identified by its normal axis and the bias (i.e. the plane passes through the point equal to normal * bias).

pub fn intersection_with_local_plane( &self, local_axis: &UnitVector<Real>, bias: Real, epsilon: Real ) -> IntersectResult<Polyline>

Computes the intersection Polylines between this mesh and a plane identified by its normal local_axis and the bias (i.e. the plane passes through the point equal to normal * bias).
