Returns bounding box of subregion with given index.
- Parameters
-
◆ get_subregion_id()
| virtual Subregion_id nv::index::ISubdivision::get_subregion_id |
( |
mi::Uint32 |
index | ) |
const |
|
pure virtual |
Returns identifier of subregion with given index.
A value of 0 represent an invalid id.
- Parameters
-
◆ get_subregion_weight()
| virtual mi::Float64 nv::index::ISubdivision::get_subregion_weight |
( |
mi::Uint32 |
index | ) |
const |
|
pure virtual |
Returns weight of subregion with given index.
A weight of 0 signifies an empty subregion. A negative value means that the real weight is unknown. A positive value represents an abstract render/memory cost value of a non-empty subregion. The weight of a spatial subregion is the sum of all estimated weights of distributed data elements,
