This topic explains how the XamScatterSurface3D™ control performance can be optimized when rendering a large set of data points.
The xamScatterSurface3D control comes optimized to render appealing 3D visualizations, which consist of thousands of points. While the precise number of points that can be rendered varies from one hardware configuration to another, there are a number of ways to optimize the performance in the control.
The following table summarizes the possible performance optimizations in the xamScatterSurface3D control. Further details are available after the table
At present, the xamScatterSurface3D control has a built-in sampling, which samples the data points bound to the control in order to improve the performance. The threshold at which sampling is applied is determined by the SamplingThreshold property.
If the number of points exceeds the SamplingThreshold value, then the points are consolidated into a regular grid with even number of rows and columns equal to the square root of SamplingThreshold value.
By default, the SamplingThreshold value is 10000 points. You can change it to better fit your needs.
You can also apply custom sampling logic to your data, before passing it to the xamScatterSurface3D control.
You can improve the xamScatterSurface3D control performance by disabling any visual properties or behaviors, which may influence the performance.
You may also set fixed values for the xamScatterSurface3D axis interval and range to improve the control performance.
Some of these features that may be disabled are listed below:
Markers
Axis grid lines
Crosshairs
Tooltip
Rotation
Scaling/zooming
