Struct bevy::render::primitives::Aabb

pub struct Aabb {
    pub center: Vec3A,
    pub half_extents: Vec3A,
}

An axis-aligned bounding box, defined by:

• a center,
• the distances from the center to each faces along the axis, the faces are orthogonal to the axis.

It is typically used as a component on an entity to represent the local space occupied by this entity, with faces orthogonal to its local axis.

This component is notably used during “frustum culling”, a process to determine if an entity should be rendered by a Camera if its bounding box intersects with the camera’s Frustum.

It will be added automatically by the systems in CalculateBounds to entities that:

• could be subject to frustum culling, for example with a Handle<Mesh> or Sprite component,
• don’t have the NoFrustumCulling component.

It won’t be updated automatically if the space occupied by the entity changes, for example if the vertex positions of a Mesh inside a Handle<Mesh> are updated.

Fields

center: Vec3A

half_extents: Vec3A

Implementations

impl Aabb

pub fn from_min_max(minimum: Vec3, maximum: Vec3) -> Aabb

pub fn enclosing<T>(iter: impl IntoIterator<Item = T>) -> Option<Aabb>where T: Borrow<Vec3>,
