Struct GltfPrimitive 

pub struct GltfPrimitive {
    pub positions: Vec<[f32; 3]>,
    pub normals: Vec<[f32; 3]>,
    pub texcoords: Vec<[f32; 2]>,
    pub indices: Vec<u32>,
}

A single draw primitive: positions, normals, and indices.

Fields

positions: Vec<[f32; 3]>

Per-vertex positions.

normals: Vec<[f32; 3]>

Per-vertex normals.

texcoords: Vec<[f32; 2]>

Per-vertex UV texture coordinates (TEXCOORD_0).

indices: Vec<u32>

Triangle indices.

Implementations

impl GltfPrimitive

pub fn bounding_box(&self) -> ([f32; 3], [f32; 3])

Compute the axis-aligned bounding box of positions. Returns (min, max) as [f32; 3] arrays.

pub fn triangle_count(&self) -> usize

Return the number of triangles (indices / 3).

pub fn vertex_count(&self) -> usize

Return the number of vertices.

pub fn extract_triangles(&self) -> Vec<[[f32; 3]; 3]>

Extract triangle vertex positions as triplets.
