Struct AtlasChart 

pub struct AtlasChart {
    pub vertices: Vec<usize>,
    pub uvs: Vec<[f64; 2]>,
    pub bbox: (f64, f64, f64, f64),
}

A single chart (UV island) for texture atlas packing.

Fields

vertices: Vec<usize>

Vertex indices belonging to this chart.

uvs: Vec<[f64; 2]>

UV coordinates for these vertices (local to [0,1]^2).

bbox: (f64, f64, f64, f64)

Axis-aligned bounding box in UV space: (min_u, min_v, max_u, max_v).

Implementations

impl AtlasChart

pub fn new(vertices: Vec<usize>, uvs: Vec<[f64; 2]>) -> Self

Create a chart from a set of vertex indices and their UV coordinates.

pub fn width(&self) -> f64

Width of the chart in UV space.

pub fn height(&self) -> f64

Height of the chart in UV space.

pub fn normalize(&mut self)

Normalize UVs to the [0, 1] range.
