Struct PointCloud 

pub struct PointCloud {
    pub points: Vec<Point>,
    pub normals: Option<Vec<Vector>>,
    pub colours: Option<Vec<[f64; 4]>>,
    pub scalars: Vec<Scalar>,
}

Points, with what was measured at each.

Every attribute present has exactly one entry per point; PointCloud::check says whether one does not.

Fields

points: Vec<Point>

The points.

normals: Option<Vec<Vector>>

A normal per point, as the file gives it, where it gives one.

colours: Option<Vec<[f64; 4]>>

An RGBA colour per point in [0, 1], where the file gives one.

scalars: Vec<Scalar>

Named scalars per point, in the order the file gives them.

Implementations

impl PointCloud

pub fn new(points: Vec<Point>) -> Self

Bare points, with nothing measured at them.

pub fn len(&self) -> usize

The number of points.

pub fn is_empty(&self) -> bool

Whether there are no points.

pub fn scalar(&self, name: &str) -> Option<&[f64]>

The values of the scalar named name.

pub fn check(&self) -> OgeomResult<()>

Check that every attribute has one entry per point.

Errors

OgeomError::Dimension naming the attribute whose length differs from the point count.
