Subset-data descriptor for tiled height-field subsets.
This interface class is used by the NVIDIA IndeX library to communicate information about tiled height-field sub-data to an application.

( |
mi::Uint32 |
tile_index | ) |
const |
|
pure virtual |
Returns the height-field data tile information for a selected data tile.
- Parameters
-
| [in] | tile_index | height-field data tile index for which to return the information. |
- Returns
- The height-field data tile information (
Data_tile_info) for the requested data tile.
◆ get_subset_data_tile_shared_border_size()
| virtual mi::Uint32 nv::index::IHeight_field_subset_data_descriptor::get_subset_data_tile_shared_border_size |
( |
| ) |
const |
|

( |
mi::Uint32 |
lod_level | ) |
const |
|
pure virtual |
Returns the data bounds covering all height-field data tiles required for the subset on a particular level-of-detail.
- Parameters
-
| [in] | lod_level | Level-of-detail for which to return the subset-data bounding box. |
- Returns
- The data bounds covering all height-field data tiles required for this subset the requested level-of-detail.

( |
| ) |
const |
|
pure virtual |
Returns the level-of-detail range used by the subset.
The components of the returned vector indicate the lowest (x-component) and hightest (y-component) level-of-detail used by the subset.
