Struct rend3::types::MeshBuilder

pub struct MeshBuilder { /* fields omitted */ }

Easy to use builder for a Mesh that deals with common operations for you.

Implementations

impl MeshBuilder

pub fn new(vertex_positions: Vec<Vec3, Global>) -> MeshBuilder

Create a new MeshBuilder with a given set of positions.

All vertices must have positions.

Panic

Will panic if the length is zero.

pub fn with_vertex_normals(self, normals: Vec<Vec3, Global>) -> MeshBuilder

Add vertex normals to the given mesh.

Panic

Will panic if the length is different from the position buffer length.

pub fn with_vertex_tangents(self, tangents: Vec<Vec3, Global>) -> MeshBuilder

Add vertex tangents to the given mesh.

Panic

Will panic if the length is different from the position buffer length.

pub fn with_vertex_uv0(self, uvs: Vec<Vec2, Global>) -> MeshBuilder

Add the first set of texture coordinates to the given mesh.

Panic

Will panic if the length is different from the position buffer length.

pub fn with_vertex_uv1(self, uvs: Vec<Vec2, Global>) -> MeshBuilder

Add the second set of texture coordinates to the given mesh.

Panic

Will panic if the length is different from the position buffer length.

pub fn with_vertex_colors(self, colors: Vec<[u8; 4], Global>) -> MeshBuilder

Add vertex colors to the given mesh.

Panic

Will panic if the length is different from the position buffer length.

pub fn with_vertex_material_indices(
    self,
    material_indices: Vec<u32, Global>
) -> MeshBuilder

Add material indices to the given mesh.

Panic

Will panic if the length is different from the position buffer length.

pub fn with_indices(self, indices: Vec<u32, Global>) -> MeshBuilder

Add indices to the given mesh.

Panic

Will panic if the length is zero.

pub fn with_right_handed(self) -> MeshBuilder

Mark this mesh as using a right handed (Counter Clockwise) winding order. It will be converted to rend3 native left handed (Clockwise) winding order on construction. This will not change the vertex normals. If this is called, it is advised to not provide a normal buffer so a buffer will be calculated for you.

See Mesh::flip_winding_order for more information.

pub fn build(self) -> Mesh

Build a mesh, adding whatever components weren’t provided.

If normals weren’t provided, they will be calculated. If mesh is right handed, will be converted to left handed.

All others will be filled with defaults.

Trait Implementations

impl Debug for MeshBuilder

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

Formats the value using the given formatter.

impl Default for MeshBuilder

pub fn default() -> MeshBuilder

Returns the “default value” for a type.
