}Expand description
Trait to control the projection matrix of a camera.
Components implementing this trait are automatically polled for changes, and used
to recompute the camera projection matrix of the Camera component attached to
the same entity as the component implementing this trait.
Use the plugins CameraProjectionPlugin and bevy::pbr::PbrProjectionPlugin to setup the
systems for your CameraProjection implementation.
Required Methods§
fn get_clip_from_view(&self) -> Mat4
fn update(&mut self, width: f32, height: f32)
fn far(&self) -> f32
fn get_frustum_corners(&self, z_near: f32, z_far: f32) -> [Vec3A; 8]
Provided Methods§
Sourcefn compute_frustum(&self, camera_transform: &GlobalTransform) -> Frustum
fn compute_frustum(&self, camera_transform: &GlobalTransform) -> Frustum
Compute camera frustum for camera with given projection and transform.
This code is called by update_frusta system
for each camera to update its frustum.
