Struct CubeBase

pub struct CubeBase;

Implements a cube as the base shape.

• 8 vertices
• 12 faces (2 triangles per face makes 12 technically)
• 18 edges

This is a cube where half the diagonal is 1.0. This is to enable this to be used in making a sphere.

Trait Implementations

impl BaseShape for CubeBase

const EDGES: usize = 18usize

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

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

The vertices for all main triangles of the shape. Check the source file for this crate and look for the constants module at the bottom for an example.

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

Main triangles for the shape; that is, the triangles which exist before subdivision.

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 CubeBase

fn clone(&self) -> CubeBase

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CubeBase

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

Formats the value using the given formatter.

impl Default for CubeBase

fn default() -> CubeBase

Returns the “default value” for a type.
