Struct RectPickResult 

pub struct RectPickResult {
    pub hits: HashMap<u64, Vec<u32>>,
}

Result of a rectangular (rubber-band) pick.

Maps each hit object’s identifier to the sub-object indices that fall inside the selection rectangle:

• For mesh objects: triangle indices whose centroid projects inside the rect.
• For point clouds: point indices whose position projects inside the rect.

Fields

hits: HashMap<u64, Vec<u32>>

Per-object sub-object indices.

Key = object identifier (mesh_index cast to u64 for scene items, crate::renderer::PointCloudItem::id for point clouds). Value = indices of triangles or points inside the rect.

Implementations

impl RectPickResult

pub fn is_empty(&self) -> bool

Returns true when no objects were hit.

pub fn total_count(&self) -> usize

Total number of sub-object indices across all hit objects.
