Struct LocalShadowChoice 

pub struct LocalShadowChoice {
    pub enabled: bool,
    pub max_distance: Option<f32>,
    pub max_lights: Option<usize>,
    pub order: ShadowOrder,
}

The options of the choice: off (no light shadowed, every light lit unshadowed), or the lights of the shadowed table’s kind whose core.light says they cast shadows and that have a range, whose range sphere meets the view’s frustum and, where max_distance is set, comes within that many metres of the eye, taken in order up to the atlas’s capacity and, where it is set, max_lights. Each option changes what is drawn, so each is the consumer’s to state: there is no default, and deserialising requires every field, null for no limit included.

Fields

enabled: bool

max_distance: Option<f32>

max_lights: Option<usize>

order: ShadowOrder

Implementations

impl LocalShadowChoice

pub fn most( &self, world: &World, kind: LightTableKind, capacity: usize, ) -> usize

The most lights this choice can shadow in world with an atlas of capacity: 0 when off, else the capacity, no more than the world’s shadow-casting lights of kind with a range, nor max_lights.

pub fn describe(&self, capacity: usize) -> String

The choice in words, for a consumer’s report.

pub fn choose( &self, world: &World, kind: LightTableKind, view: &ShadowView, capacity: usize, ) -> ChosenShadows

The lights of kind in world this choice shadows for view, at most capacity, in the choice’s order.
