Trait Implementations

impl BoundingVolume for Aabb3d

fn transformed_by( self, translation: impl Into<Self::Translation>, rotation: impl Into<Self::Rotation>, ) -> Self

Transforms the bounding volume by first rotating it around the origin and then applying a translation.

The result is an Axis-Aligned Bounding Box that encompasses the rotated shape.

Note that the result may not be as tightly fitting as the original, and repeated rotations can cause the AABB to grow indefinitely. Avoid applying multiple rotations to the same AABB, and consider storing the original AABB and rotating that every time instead.

fn transform_by( &mut self, translation: impl Into<Self::Translation>, rotation: impl Into<Self::Rotation>, )

Transforms the bounding volume by first rotating it around the origin and then applying a translation.

The result is an Axis-Aligned Bounding Box that encompasses the rotated shape.

Note that the result may not be as tightly fitting as the original, and repeated rotations can cause the AABB to grow indefinitely. Avoid applying multiple rotations to the same AABB, and consider storing the original AABB and rotating that every time instead.

fn rotated_by(self, rotation: impl Into<Self::Rotation>) -> Self

Rotates the bounding volume around the origin by the given rotation.

The result is an Axis-Aligned Bounding Box that encompasses the rotated shape.

Note that the result may not be as tightly fitting as the original, and repeated rotations can cause the AABB to grow indefinitely. Avoid applying multiple rotations to the same AABB, and consider storing the original AABB and rotating that every time instead.

fn rotate_by(&mut self, rotation: impl Into<Self::Rotation>)

Rotates the bounding volume around the origin by the given rotation.

The result is an Axis-Aligned Bounding Box that encompasses the rotated shape.

Note that the result may not be as tightly fitting as the original, and repeated rotations can cause the AABB to grow indefinitely. Avoid applying multiple rotations to the same AABB, and consider storing the original AABB and rotating that every time instead.

type Translation = Vec3A
