    pub z: f64,
    pub intensity: u16,
    pub return_number: u8,

    pub gps_time: Option<f64>,
    pub red: Option<u16>,
    pub green: Option<u16>,
    pub blue: Option<u16>,
}

A single LAS/LAZ point record.

Covers the core fields present in all LAS point data format IDs (0–10). Optional fields (gps_time, red, green, blue) are None for format IDs that do not carry them.

Fields

x: f64

X coordinate (scaled and offset per LAS header).

y: f64

Y coordinate (scaled and offset per LAS header).

z: f64

Z coordinate (scaled and offset per LAS header).

intensity: u16

Laser pulse return intensity (0–65535).

return_number: u8

Return number within the pulse (1-based, ≤ number_of_returns).

number_of_returns: u8

Total number of returns for this pulse.

classification: u8

ASPRS classification code (see Point3D::classification_name).

scan_angle_rank: i8

Scan angle rank in degrees (−90 to +90, rounded to integer for formats 0-5).

user_data: u8

User-defined data byte.

point_source_id: u16

Point source ID (flight line ID for airborne surveys).

gps_time: Option<f64>

GPS time of the point (present in formats 1, 3, 5, 6–10).

red: Option<u16>

Red channel colour value (present in formats 2, 3, 5, 7, 8).

green: Option<u16>

Green channel colour value (present in formats 2, 3, 5, 7, 8).

blue: Option<u16>

Blue channel colour value (present in formats 2, 3, 5, 7, 8).

Implementations

impl Point3D

pub fn new(x: f64, y: f64, z: f64) -> Self

Create a new point at (x, y, z) with all other fields zeroed / None.

pub fn with_intensity(self, intensity: u16) -> Self

Builder: set the intensity value.

pub fn with_classification(self, class: u8) -> Self

Builder: set the ASPRS classification code.

pub fn with_color(self, r: u16, g: u16, b: u16) -> Self

Builder: set red / green / blue colour values.

pub fn with_gps_time(self, t: f64) -> Self

Builder: set the GPS timestamp.

pub fn distance_to(&self, other: &Point3D) -> f64

3-D Euclidean distance to another point.

pub fn distance_2d(&self, other: &Point3D) -> f64

2-D horizontal distance (ignores Z) to another point.

pub fn classification_name(&self) -> &'static str

Human-readable name for the ASPRS LAS 1.4 classification code.

Returns the standard name for codes 0–18 and "Reserved/Unknown" for everything else.

Trait Implementations

impl Clone for Point3D

fn clone(&self) -> Point3D

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Point3D

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

Formats the value using the given formatter.

impl PartialEq for Point3D

fn eq(&self, other: &Point3D) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
