Struct KleinBottle 

pub struct KleinBottle {
    pub scale: f32,
}

The Klein bottle — a non-orientable closed surface. Uses the “figure-8” immersion in R^3.

Fields

scale: f32

Implementations

impl KleinBottle

pub fn new(scale: f32) -> Self

Trait Implementations

impl Clone for KleinBottle

fn clone(&self) -> KleinBottle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KleinBottle

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

Formats the value using the given formatter.

impl Default for KleinBottle

fn default() -> Self

Returns the “default value” for a type.

impl Surface for KleinBottle

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

Evaluate the surface position at parameter (u, v).

fn wraps_u(&self) -> bool

Whether the surface wraps in u. Used for seamless tessellation.

fn wraps_v(&self) -> bool

Whether the surface wraps in v. Used for seamless tessellation.

fn name(&self) -> &str

Human-readable name for debugging.

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

Compute the surface normal at parameter (u, v). Default implementation uses central differences.

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

Compute the partial derivative with respect to u at (u, v).

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

Compute the partial derivative with respect to v at (u, v).

fn u_range(&self) -> (f32, f32)

Parameter domain for u: (min, max). Defaults to (0, 1).

fn v_range(&self) -> (f32, f32)

Parameter domain for v: (min, max). Defaults to (0, 1).
