Overview of Point Clouds

Visualize SDK provides you a set of interfaces to render point clouds independently (separate from .dwg file unlike Drawings SDK).

Visualize SDK provides the following classes to represent point cloud data:

OdTvPointCloudData – corresponds to the case when all points data would be loaded into memory and stored within array;
OdTvRcsPointCloudData – corresponds to the case when points data loading would be performed by demand of rendering pipeline using OdRcsDataManager from PointCloud SDK.

There are two groups of methods used to append point cloud geometry to the Visualize entity of type OdTvEntity:

appendPointCloud	appendRcsPointCloud
`OdTvEntity::appendPointCloud (OdInt32, OdTvPoint, OdTvResult);`	`OdTvEntity::appendRcsPointCloud (OdPointCloudScanDatabasePtr, OdPointCloudProjectDatabasePtr, OdTvResult*);`
`OdTvEntity::appendPointCloud (OdPointCloudDataSourcePtr, OdTvResult*);`	`OdTvEntity::appendRcsPointCloud (OdPointCloudDataSourcePtr, OdString&, OdTvResult*);`
`OdTvEntity::appendPointCloud (OdTvPointArray&, OdTvResult*)`

For more details about these methods, please see the corresponding topics of Visualize SDK API Reference.
