Struct TrimRectangle 

pub struct TrimRectangle {
    pub u1: f64,
    pub v1: f64,
    pub u2: f64,
    pub v2: f64,
    pub usense: bool,
    pub vsense: bool,
}

The parameter rectangle cut from a surface, with senses intact.

Kept as a struct rather than four loose numbers because the sense flags are meaningless without the bounds they qualify, and a caller that fetches the bounds without the senses will build the complementary patch on a periodic surface.

Fields

u1: f64

First u parameter, as written.

v1: f64

First v parameter, as written.

u2: f64

Second u parameter, as written.

v2: f64

Second v parameter, as written.

usense: bool

Does u run from u1 to u2 in increasing parameter order?

vsense: bool

Does v run from v1 to v2 in increasing parameter order?

Implementations

impl TrimRectangle

pub fn u_wraps(&self) -> bool

Does the u range wrap through the surface’s period?

True when u1 > u2 while usense claims increasing order, which is only consistent on a closed parameter direction. Useful as a check: a file asserting this for a plane is inconsistent, and a kernel that clamps rather than wraps will produce an empty patch.

pub fn v_wraps(&self) -> bool

Does the v range wrap through the surface’s period?
