Struct GpuMesh 

pub struct GpuMesh {
    pub vertices: Vec<[f32; 3]>,
    pub normals: Vec<[f32; 3]>,
    pub indices: Vec<[u32; 3]>,
    pub tex_coords: Vec<[f32; 2]>,
}

Triangle mesh stored in GPU-friendly interleaved layout.

Each vertex holds a position, a normal, and a UV texture coordinate. Triangles are stored as [i, j, k] index triples.

Fields

vertices: Vec<[f32; 3]>

Vertex positions [x, y, z].

normals: Vec<[f32; 3]>

Per-vertex normals [nx, ny, nz].

indices: Vec<[u32; 3]>

Triangle index triples.

tex_coords: Vec<[f32; 2]>

Per-vertex UV texture coordinates [u, v].
