Struct MobiusNavigation 

pub struct MobiusNavigation {
    pub strip: MobiusStrip,
    pub u: f32,
    pub v: f32,
    pub loops: u32,
}

Handles movement on a Mobius strip with automatic face switching.

Fields

strip: MobiusStrip

u: f32

Parameter along the strip center, in [0, 2*PI)

v: f32

Parameter across the strip, in [-1, 1]

loops: u32

How many times we have gone fully around

Implementations

impl MobiusNavigation

pub fn new(strip: MobiusStrip) -> Self

pub fn move_by(&mut self, du: f32, dv: f32)

Move along the strip (du) and across it (dv). When crossing u = 2*PI, v is negated (you switch to the other side).

pub fn position(&self) -> Vec3

Get the current 3D position on the strip.

pub fn on_backside(&self) -> bool

Check if currently on the “back side” (odd number of loops).

pub fn current_normal(&self) -> Vec3

Get the surface normal at the current position.

pub fn reset(&mut self)

Reset to starting position.
