Struct CopcInfo 

#[non_exhaustive]
pub struct CopcInfo {
    pub center: [f64; 3],
    pub halfsize: f64,
    pub spacing: f64,
    pub root_hier_offset: u64,
    pub root_hier_size: u64,
    pub gpstime_minimum: f64,
    pub gpstime_maximum: f64,
}

COPC info VLR payload (160 bytes). This is COPC-specific — not part of the LAS standard.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

center: [f64; 3]

Centre of the root octree cube [x, y, z].

halfsize: f64

Half the side length of the root octree cube.

spacing: f64

Spacing at the finest octree level.

root_hier_offset: u64

File offset of the root hierarchy page.

root_hier_size: u64

Size of the root hierarchy page in bytes.

gpstime_minimum: f64

Minimum GPS time across all points.

gpstime_maximum: f64

Maximum GPS time across all points.

Implementations

impl CopcInfo

pub fn root_bounds(&self) -> Aabb

Compute the root octree bounding box from center + halfsize.

pub fn level_for_resolution(&self, resolution: f64) -> i32

Compute the octree level needed for a given point spacing (in the same units as the point coordinates, typically meters).

At level 0 the average distance between points equals CopcInfo::spacing. Each deeper level halves the distance. This returns the shallowest level where the point spacing is ≤ resolution.

For example, if the file’s base spacing is 10 m and you request 0.5 m, you get level 5 (10 → 5 → 2.5 → 1.25 → 0.625 → 0.3125).

Use the returned level as max_level in CopcStreamingReader::query_points_to_level or CopcStreamingReader::load_hierarchy_for_bounds_to_level.
