In C#:

…
var diffuseMaterial = new DiffuseMaterial();
diffuseMaterial.Brush = new SolidColorBrush(Colors.Red);
SurfaceChart.ShowPointMarkers = true;
SurfaceChart.PointMarkerMaterial = diffuseMaterial;

In Visual Basic:

…
Dim diffuseMaterial = New DiffuseMaterial()
diffuseMaterial.Brush = New SolidColorBrush(Colors.Red)
SurfaceChart.ShowPointMarkers = True
SurfaceChart.PointMarkerMaterial = diffuseMaterial

Configuring Data Point Marker Mesh

Overview

Use the XamScatterSurface3D PointMarkerMesh property to configure the 3D marker shape.

Configuring Data Point Marker Template

Overview

Use the XamScatterSurface3D PointMarkerTemplate property to use a DataTemplate for xamScatterSurface3D control markers.

Note
Note

In order for the DataTemplate to be visible, the PointMarkerMaterial should have the Viewport2DVisual3D.IsVisualHostMaterial attached property set to True.

Property settings

The following table maps the desired configuration to the property settings that manage it.

In order to: Use this property: And set it to:

Set a DataTemplate for each marker

DataTemplate

Example

The screenshot below demonstrates how the xamScatterSurface3D control looks as a result of the following code:
