Detailed Description

Configuration settings for spatial subdivision.

Member Enumeration Documentation

◆ Subdivision_mode

enum nv::index::IConfig_settings::Subdivision_config::Subdivision_mode

Spatial subdivision modes.

Enumerator
SUBDIVIDE_USING_GRID 

Subdivide scene using a regular 3D grid. The grid cell size is based on subcube size settings.

SUBDIVIDE_USING_KD_TREE 

Subdivide scene adaptively into number_adaptive_parts, using a Kd-tree. 

        Volume and surface importers should support bounding box estimation for a balanced load 
        distribution to parts. The estimation should be proportional to the number of primitives in the bounding box,
        like cells, faces or particles. If importers do not support estimation, they should return a value of 1
        for non-empty bounding boxes, and a value of 0 for empty bounding boxes.
        The subdivision will then be based on the volume (and other scene elements).

Member Data Documentation

◆ save_subdivision

bool nv::index::IConfig_settings::Subdivision_config::save_subdivision

Save generated subdivision. This can be used to avoid subdivision work on later scene loads.

◆ subdivision_mode

Subdivision_mode nv::index::IConfig_settings::Subdivision_config::subdivision_mode

Spatial subdivision mode used for complete scene.

◆ subdivision_part_count

mi::Uint32 nv::index::IConfig_settings::Subdivision_config::subdivision_part_count

Number of parts the scene should be subdivided. Used in adaptive subdivision modes like SUBDIVIDE_USING_KD_TREE.

◆ suppress_x_axis_subdivision

bool nv::index::IConfig_settings::Subdivision_config::suppress_x_axis_subdivision

Suppress subdivision of X-axis.

◆ suppress_y_axis_subdivision

bool nv::index::IConfig_settings::Subdivision_config::suppress_y_axis_subdivision

Suppress subdivision of Y-axis.

◆ suppress_z_axis_subdivision

bool nv::index::IConfig_settings::Subdivision_config::suppress_z_axis_subdivision

Suppress subdivision of Z-axis.
