Struct Patch

pub struct Patch {
    pub u_start: Scalar,
    pub u_end: Scalar,
    pub v_start: Scalar,
    pub v_end: Scalar,
}

A finite parameter rectangle for tessellation.

Elementary surfaces are infinite (a plane, a cylinder) or only periodic in one direction, so a caller must say which patch it wants. Returning a default would invent geometry the source never declared.

Fields

u_start: Scalar

Start of the u interval.

u_end: Scalar

End of the u interval.

v_start: Scalar

Start of the v interval.

v_end: Scalar

End of the v interval.

Implementations

impl Patch

pub fn new( u_start: Scalar, u_end: Scalar, v_start: Scalar, v_end: Scalar, ) -> GeomResult<Self>

Construct a patch, rejecting an empty or non-finite rectangle.

pub fn full_turn(v_start: Scalar, v_end: Scalar) -> GeomResult<Self>

The full closed patch for a family that is periodic in u.

Trait Implementations

impl Clone for Patch

fn clone(&self) -> Patch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Patch

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

Formats the value using the given formatter.

impl PartialEq for Patch

fn eq(&self, other: &Patch) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
