Struct SpaceTree 

pub struct SpaceTree<'a> {
    pub cells: Vec<Cell<'a>>,
    pub surfaces: Vec<Placed<'a>>,
}

The spaces of a window’s scene and the scenes behind its doorways, and their mesh surfaces, in the order the composition holds them.

Fields

cells: Vec<Cell<'a>>

The spaces; the first is the window scene’s own.

surfaces: Vec<Placed<'a>>

The mesh surfaces, in draw order.

Implementations

impl<'a> SpaceTree<'a>

pub fn of(scene_layer: &'a LayerNode) -> Option<Self>

The spaces and surfaces of the scene scene_layer shows; None when it shows none.

pub fn holds_scene(&self, layer: &LayerNode) -> bool

Whether layer is one of the tree’s scenes.

pub fn cell_along(&self, path: &[usize]) -> usize

The space an eye that walked through the doorways of the scene nodes path stands in: as far along the path as its doorways still lead.

pub fn to_root(&self, cell: usize) -> Mat4

Maps space cell into the window scene’s.
