Struct Patch

Source

pub struct Patch {
    pub u_start: f64,
    pub u_end: f64,
    pub v_start: f64,
    pub v_end: f64,
}

Expand description

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: f64

Start of the u interval.

§u_end: f64

End of the u interval.

§v_start: f64

Start of the v interval.

§v_end: f64

End of the v interval.

Implementations§

Source §

impl Patch

Source

pub fn new( u_start: f64, u_end: f64, v_start: f64, v_end: f64, ) -> Result<Patch, GeomError>

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

Source

pub fn full_turn(v_start: f64, v_end: f64) -> Result<Patch, GeomError>

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