pub fn root_mut(&mut self) -> &mut ImageSpace

pub fn get(&self, id: ImageSpaceId) -> Option<&ImageSpace>

pub fn get_mut(&mut self, id: ImageSpaceId) -> Option<&mut ImageSpace>

pub fn placed(&self, id: ImageSpaceId) -> bool

pub fn to_root(&self, image: ImageSpaceId) -> Option<Placement>

The composed placement from image into the root, None for a space never placed, unplaced, or whose slot a later place reused.

pub fn depth(&self, point: [f32; 3]) -> Option<f32>

The root eye’s projective depth of an image-space position; None nearer than its near plane.

pub fn ndc(&self, point: [f32; 3]) -> Option<[f32; 2]>
