Implementations

impl ModelBounds

pub fn new() -> Self

Create new bounds initialized to invalid state

pub fn is_valid(&self) -> bool

Check if bounds are valid (at least one point added)

pub fn expand(&mut self, x: f64, y: f64, z: f64)

Expand bounds to include a point

pub fn centroid(&self) -> (f64, f64, f64)

Get centroid (center of bounding box)

pub fn has_large_coordinates(&self, length_unit_scale: f64) -> bool

Check if bounds reach more than crate::limits::LARGE_COORD_THRESHOLD_METERS (1 km, in METRES; was 10 km before #4934) from the origin.

The sampled values are raw IfcCartesianPoint coordinates in the file’s length unit, so the caller passes length_unit_scale (file unit to metres, e.g. 0.001 for millimetres, 1000.0 for kilometres) and the comparison happens in metres. Gating on the raw values against a metre-shaped constant let a kilometre-unit model 500 000 km out read as “500 < 1000” and skip the RTC rebase, and the caller’s scaling afterwards could not undo a decision already taken.

pub fn rtc_offset(&self, length_unit_scale: f64) -> Option<RtcVerdict>

The RTC verdict in metres: None when no point was sampled, Large with the unit-scaled bbox centre when a corner is past the threshold (see has_large_coordinates), Small otherwise. The centre can be inside the threshold while a corner is not, which is why the decision is carried rather than re-derived from it.
