Struct crystal_ball::shapes::TriangleMesh

pub struct TriangleMesh {
    pub indices: Vec<u32>,
    pub vertices: Vec<Point3>,
    pub normals: Vec<Vec3>,
    pub tangents: Vec<Vec4>,
    pub uvs: Vec<Point2>,
}

A mesh consisting of multiple triangles.

When applying transformations such as Transformable::rotate_x, TriangleMesh::vertex_mean is used as the origin.

This struct does not store any Triangles directly. Instead it contains the necessary buffers to create the individual triangles.

Fields

indices: Vec<u32>

vertices: Vec<Point3>

normals: Vec<Vec3>

tangents: Vec<Vec4>

uvs: Vec<Point2>

Implementations

impl TriangleMesh

pub fn new( indices: Vec<u32>, vertices: Vec<Point3>, normals: Vec<Vec3>, tangents: Vec<Vec4>, uvs: Vec<Point2> ) -> Self

Create a new TriangleMesh.

pub fn triangle(leg_length: f64) -> TriangleMesh

Create a new TriangleMesh consisting of a single triangle.

pub fn plane(half_size: f64) -> TriangleMesh

Create a new TriangleMesh consisting of a single plane.

pub fn cube(half_size: f64) -> TriangleMesh

Create a new TriangleMesh consisting of a single cube.

pub fn vertex_mean(&self) -> Point3

Calculate the triangle mesh’s vertex mean.

pub fn triangles(self) -> impl Iterator<Item = Triangle>

Return an iterator over the triangle mesh’s individual triangles.

These triangles can then be used to construct a Mesh.
