Struct MobiusStrip 

pub struct MobiusStrip {
    pub radius: f32,
    pub width: f32,
}

A Mobius strip parameterized by radius (center circle) and width (strip half-width).

Fields

radius: f32

width: f32

Implementations

impl MobiusStrip

pub fn new(radius: f32, width: f32) -> Self

pub fn parametric(&self, u: f32, v: f32) -> Vec3

Parametric surface of the Mobius strip. u in [0, 2*PI) — around the strip v in [-1, 1] — across the strip width

pub fn position_on_strip(&self, t: f32, s: f32) -> Vec3

Position on the strip given: t in [0, 1) — fraction around the strip s in [-1, 1] — fraction across the strip width

pub fn normal_at(&self, u: f32, v: f32) -> Vec3

Surface normal at (u, v). The normal flips sign after one full loop (u -> u + 2*PI), demonstrating the one-sidedness of the Mobius strip.

pub fn walk(&self, distance: f32) -> (Vec3, bool)

Walk a given distance along the center of the strip. Returns (position, on_backside). After traveling the full circumference (2PIradius), you end up on the back side.

pub fn generate_mesh(&self, u_steps: usize, v_steps: usize) -> Vec<Vec3>

Generate a mesh of the strip for rendering.

pub fn centerline(&self, steps: usize) -> Vec<Vec3>

Generate the centerline of the strip.
