Struct EyeView 

pub struct EyeView<'a> {
    pub camera: Camera,
    pub size: Size,
    pub cell: usize,
    pub seen: Vec<SeenSpace>,
    pub surfaces: Vec<SeenSurface<'a>>,
}

Where the window’s eye stands, with its camera, and what it sees from there: the spaces it sees through doorways and their surfaces, all in the coordinates of the space it stands in.

Fields

camera: Camera

The eye’s camera.

size: Size

The window scene node’s size, which the camera fills.

cell: usize

The space the eye stands in, by its number in the tree.

seen: Vec<SeenSpace>

The spaces the eye sees: its own first, then each through the doorway it shows through, before the spaces seen through it.

surfaces: Vec<SeenSurface<'a>>

The surfaces of the spaces it sees, in draw order.

Implementations

impl<'a> EyeView<'a>

pub fn of(tree: &SpaceTree<'a>, size: Size) -> Self

What the window’s eye sees of tree, the scene of a node of size: it stands where the window scene’s Scene3d::eye says, and sees through each doorway whose opening shows on screen.

pub fn build_world(&self, tree: &SpaceTree<'_>, world: &mut EyeWorld)

Fills world with what the eye can bump into and walk through: the space it stands in, the spaces one doorway from it, their solid surfaces and the doorways between them, in the eye’s space.

impl EyeView<'_>

pub fn content_to_window( &self, seen: &SeenSurface<'_>, to_window: ProjectiveTransform, ) -> Option<ProjectiveTransform>

The map from the content of seen surface seen to the window, as the eye shows it, given to_window for the scene node’s own coordinates; None for a surface whose mesh carries no texture plane.
