Struct Frame

Source

pub struct Frame {
    pub origin: DVec3,
    pub x: DVec3,
    pub y: DVec3,
}

Expand description

An orthonormal frame at a point on a path.

A sweep needs a full frame, not just a tangent: the profile’s x and y axes have to be carried along the path, and how they are carried is exactly what distinguishes the sweep families from each other.

Fields§

§origin: DVec3

Frame origin on the directrix.

§x: DVec3

Image of the profile’s +x.

§y: DVec3

Image of the profile’s +y.

Implementations§

Source §

impl Frame

Source

pub fn from_reference( origin: DVec3, tangent: DVec3, reference: DVec3, ) -> Result<Frame, GeomError>

Frame whose z is tangent and whose x is reference made perpendicular to it.

Refuses a reference parallel to the tangent instead of silently picking a fallback axis: the caller supplied a direction that cannot orient the profile, and quietly substituting one rotates the section by an arbitrary angle.
