Struct RuledSurface 

pub struct RuledSurface {
    pub curve_a: Box<dyn Fn(f32) -> Vec3 + Send + Sync>,
    pub curve_b: Box<dyn Fn(f32) -> Vec3 + Send + Sync>,
    /* private fields */
}

Create a ruled surface between two space curves.

Given curves a(t) and b(t) for t in [0,1], the ruled surface is S(u, v) = (1-v) * a(u) + v * b(u).

Fields

curve_a: Box<dyn Fn(f32) -> Vec3 + Send + Sync>

curve_b: Box<dyn Fn(f32) -> Vec3 + Send + Sync>

Implementations

impl RuledSurface

pub fn new<A, B>(curve_a: A, curve_b: B) -> Self

where A: Fn(f32) -> Vec3 + Send + Sync + 'static, B: Fn(f32) -> Vec3 + Send + Sync + 'static,

Trait Implementations

impl Surface for RuledSurface

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

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

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).

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.
