Struct Helicoid 

pub struct Helicoid {
    pub pitch: f32,
    pub radius: f32,
    pub height_range: f32,
}

A helicoid — a minimal surface swept by a line rotating about and translating along an axis.

Fields

pitch: f32

radius: f32

height_range: f32

Implementations

impl Helicoid

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

Trait Implementations

impl Clone for Helicoid

fn clone(&self) -> Helicoid

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Helicoid

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

Formats the value using the given formatter.

impl Default for Helicoid

fn default() -> Self

Returns the “default value” for a type.

impl Surface for Helicoid

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

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

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

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

fn name(&self) -> &str

Human-readable name for debugging.

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).

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.
