Struct Control 

pub struct Control {
    pub orientation: Orientation,
    pub twist: f64,
    pub end_scale: f64,
    pub rails: Vec<Chain<NurbCurve3D>>,
}

How the profile changes as it travels, besides being carried along the path (see sweep_along). Every section of the sweep is the profile mapped about the path’s start point in the profile’s plane — its centre — by a turn and a scale:

• twist and scale grow evenly with the length travelled, from none to twist (radians, counter-clockwise in the profile’s plane as drawn) and from one to end_scale;
• rails, one or two, decide them instead: where each rail crosses a section is where the profile’s point it starts at goes. One rail turns and scales the profile uniformly about the centre; two map it linearly, which scales it differently along different directions. That is the sweep following the path and its first guide: with Orientation::FollowPath the section planes are square to the path, and the rails turn the profile within them.

Fields

orientation: Orientation

twist: f64

end_scale: f64

rails: Vec<Chain<NurbCurve3D>>

Implementations

impl Control

pub fn is_plain(&self) -> bool

Whether the profile only travels, neither twisted, scaled nor following rails — which needs no sampling (see the module docs).

Trait Implementations

impl Clone for Control

fn clone(&self) -> Control

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Control

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

Formats the value using the given formatter.

impl Default for Control

fn default() -> Self

Carried along the path, unchanged.
