Struct NodeIdToIndexMapper

Source

pub struct NodeIdToIndexMapper {
    spatial_node_map: FastHashMap<SpatialId, SpatialNodeIndex>,
}

Expand description

A data structure that keeps track of mapping between API Ids for spatials and the indices used internally in the SpatialTree to avoid having to do HashMap lookups for primitives and clips during frame building.

Fields§

§spatial_node_map: FastHashMap<SpatialId, SpatialNodeIndex>
