Struct TerrainLodParams

Source

pub struct TerrainLodParams {
    pub num_levels: usize,
    pub thresholds: Vec<f32>,
    pub divisors: Vec<usize>,
}

Expand description

Parameters for heightmap LOD (level-of-detail) scaling.

Fields§

§num_levels: usize

Number of LOD levels.

§thresholds: Vec<f32>

Distance threshold per level (in world units).

§divisors: Vec<usize>

Resolution divisor per level (1 = full, 2 = half, 4 = quarter, …).

where T: Any,

Source §

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

Source §

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

Source §

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.
