The iOS Point-Cloud Chart 3D demonstrates how to create a high-performance iOS 3D chart with two-dimensional markers using the SciChart for iOS 3D charting component. The 3D Point-Cloud is provided by SCIScatterRenderableSeries3D Series and defined by SCIXyzDataSeries3D.

The shapes of the scatters in the point-cloud is set by the pointmarkers. There SCIScatterRenderableSeries3D supports multiple 3D pointmarkers out of the box, including:

• – SpherePointMarker3D
• – CubePointMarker3D
• – PyramidPointMarker3D;
• – CylinderPointMarker3D

Scatter points may be colored or scaled individually using the SCIPointMetadata3D API.

To learn more about how to create a point-cloud 3D chart in iOS SWIFT and Objective-C, please read SciChart iOS 3D documentation about The Scatter 3D Chart Type.
