Struct hexasphere::shapes::TriangleBase

pub struct TriangleBase;

Implements a single triangle as the base shape.

• 3 vertices
• 1 face
• 3 edges

This is a triangle on the XZ plane. The circumscribed circle on the triangle has radius 1.0.

Trait Implementations

impl BaseShape for TriangleBase

fn initial_points(&self) -> Vec<Vec3A>

The initial vertices for the triangle. Note that Vec3A::new is not a const fn(), hence I recommend you use lazy_static. Check the source file for this crate and look for the constants module at the bottom for an example.

fn triangles(&self) -> Box<[Triangle]>

Base triangles for the shape.

const EDGES: usize = 3usize

Number of unique edges defined in the contents of triangles(). This number is 5 for a square for example:

fn interpolate(&self, a: Vec3A, b: Vec3A, p: f32) -> Vec3A

Basic function used for interpolation. When p is 0.0, a is expected. When p is 1.0, b is expected. There are three options already implemented in this crate:

fn interpolate_half(&self, a: Vec3A, b: Vec3A) -> Vec3A

If an optimization is available for the case where p is 0.5, this function should implement it. This defaults to calling interpolate(a, b, 0.5) however.

fn interpolate_multiple( &self, a: Vec3A, b: Vec3A, indices: &[u32], points: &mut [Vec3A] )

If an optimization is available for the case where p varies but a and b don’t this function should implement it.

impl Clone for TriangleBase

fn clone(&self) -> TriangleBase

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TriangleBase

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

Formats the value using the given formatter.

impl Default for TriangleBase

fn default() -> TriangleBase

Returns the “default value” for a type.

impl Copy for TriangleBase
