Struct RevolutionSurface 

pub struct RevolutionSurface {
    pub profile: Box<dyn Fn(f32) -> (f32, f32) + Send + Sync>,
    /* private fields */
}

Create a surface of revolution from a 2D profile curve.

The profile is a function f(v) -> (radius, height) where v is in [0, 1]. The surface revolves around the Y axis.

Fields

profile: Box<dyn Fn(f32) -> (f32, f32) + Send + Sync>

Implementations

impl RevolutionSurface

pub fn new<F>(profile: F) -> Self

where F: Fn(f32) -> (f32, f32) + Send + Sync + 'static,

pub fn with_name(self, name: &str) -> Self

Trait Implementations

impl Surface for RevolutionSurface

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 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_v(&self) -> bool

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