The Point-Cloud Chart demo shows how to create high-performance Android 3D Point Cloud with two-dimensional markers chart using the SciChart Android 3D Component.

The 3D Point Cloud is provided by the ScatterRenderableSeries3D type and defined by XyzDataSeries3D. It also requires a PointMarker. The ScatterRenderableSeries3D supports multiple pointmarkers, in 3D those include:

• SpherePointMarker3D;
• CubePointMarker3D;
• PyramidPointMarker3D;
• CylinderPointMarker3D.

Scatter points may be colored or scaled individually using the PointMetada3D API

To learn more, read SciChart Android 3D documentation about The Scatter 3D Chart Type.
