Represents a complete mesh with vertex data and indices.

Fields

positions: Vec<Vec3>

Vertex positions

normals: Option<Vec<Vec3>>

Vertex normals

tex_coords: Option<Vec<Vec2>>

Vertex texture coordinates

tangents: Option<Vec<Vec4>>

Vertex tangents (for normal mapping)

colors: Option<Vec<Vec4>>

Vertex colors

indices: Option<Vec<u32>>

Index data for primitive assembly

primitive_type: PrimitiveTopology

Type of primitives to render

bounding_box: Aabb

Axis-aligned bounding box

vertex_layout: Vec<VertexAttributeDescriptor>

Vertex format layout

Implementations

impl Mesh

pub fn vertex_size(&self) -> usize

Calculates the stride of a single vertex in bytes based on the vertex layout.

pub fn create_vertex_buffer(&self) -> Vec<u8>

Creates an interleaved vertex buffer from the mesh data, ready for GPU upload.

This function converts the struct-of-arrays (SoA) data layout of the Mesh struct into an array-of-structs (AoS) layout in a raw byte buffer. The exact memory layout is dictated by the vertex_layout field.

Trait Implementations

impl AssetDecoder<Mesh> for MeshDispatcher

fn load(&self, bytes: &[u8]) -> Result<Mesh, Box<dyn Error + Send + Sync>>

Parses a byte slice and converts it into an instance of the asset A.

impl Debug for Mesh

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

Formats the value using the given formatter.
