Struct ObjLod 

pub struct ObjLod {
    pub levels: Vec<ObjMesh>,
    pub thresholds: Vec<f64>,
}

A level-of-detail collection: multiple meshes at decreasing resolution.

Fields

levels: Vec<ObjMesh>

LOD levels, index 0 = highest detail.

thresholds: Vec<f64>

Distance thresholds at which to switch to the next LOD level. thresholds[i] is the max distance for levels[i].

Implementations

impl ObjLod

pub fn new() -> Self

Create an empty LOD set.

pub fn push(&mut self, mesh: ObjMesh, threshold: f64)

Add a LOD level with the given switch distance.

pub fn select(&self, distance: f64) -> Option<&ObjMesh>

Select the appropriate LOD level for a viewing distance.

pub fn num_levels(&self) -> usize

Number of LOD levels.

pub fn decimate(mesh: &ObjMesh, target_faces: usize) -> ObjMesh

Simplify a mesh to approximately target_faces triangles by removing every other face (simple decimation placeholder).

Trait Implementations

impl Clone for ObjLod

fn clone(&self) -> ObjLod

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ObjLod

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ObjLod

fn default() -> ObjLod

Returns the “default value” for a type.
