Struct Pointer 

pub struct Pointer {
    pub ray: Ray,
    pub reach: Reach,
    pub cycle: usize,
}

Where the pointer is: the ray from the eye through it, how far from that ray it reaches, and which of what lies under it it means.

Fields

ray: Ray

reach: Reach

cycle: usize

Which of what lies under the pointer it means, counted front to back from the one a click picks first (see super::hit::Scene::under), wrapping round: a secondary click steps one further behind, and any move of the pointer starts again from the front. A pick, a hover and a click alike take the one this names, so what is lit is what a click holds.

Implementations

impl Pointer

pub fn moved(&self, motion: &Motion) -> GeopResult<Self>

The pointer moved by motion: into the frame of a part placed in the part drawn, for a step of it to be edited where it is placed. A rigid motion leaves its reach as it is.

pub fn cycled(self, cycle: usize) -> Self

The same pointer, meaning the cycle-th of what lies under it (see Pointer::cycle).

pub fn reach_at(&self, reaches: f64, t: Scalar) -> Scalar

reaches of the pointer’s reach, t along its ray.

pub fn within(&self, dist: Scalar, t: Scalar, reaches: f64) -> bool

Whether something dist from the ray, t along it, could lie within reaches of it.
