  • Reference

Definition

Namespace:
System.Windows.Media.Media3D
Assembly:
PresentationCore.dll

Gets the distance between the point of intersection and the ray's origin in the coordinate space of Visual3D which initiated the hit test.

public:
 virtual property double DistanceToRayOrigin { double get(); };
public override double DistanceToRayOrigin { get; }
member this.DistanceToRayOrigin : double
Public Overrides ReadOnly Property DistanceToRayOrigin As Double

Property Value

Double

Double that indicates the distance between the point of intersection and the ray's origin in the coordinate space of Visual3D which initiated the hit test.

Examples

The following code excerpt reads this property.

public void UpdateResultInfo(RayMeshGeometry3DHitTestResult rayMeshResult)
{
    HitVisualInfo.Text = rayMeshResult.VisualHit.ToString();
    HitModelInfo.Text = rayMeshResult.ModelHit.ToString();
    HitMeshInfo.Text = rayMeshResult.MeshHit.ToString();
    //HitMaterialInfo.Text = (rayMeshResult.ModelHit as GeometryModel3D).Material.GetType().Name;
    //HitMaterialBrushInfo.Text = ((rayMeshResult.ModelHit as GeometryModel3D).Material as DiffuseMaterial).Brush.ToString();
    HitDistanceInfo.Text = rayMeshResult.DistanceToRayOrigin.ToString();
    Vertex1Info.Text = (rayMeshResult.VertexWeight1 * 100) + "%";
    Vertex2Info.Text = (rayMeshResult.VertexWeight2 * 100) + "%";
    Vertex3Info.Text = (rayMeshResult.VertexWeight3 * 100) + "%";
}

Public Sub UpdateResultInfo(ByVal rayMeshResult As RayMeshGeometry3DHitTestResult)
    HitVisualInfo.Text = rayMeshResult.VisualHit.ToString()
    HitModelInfo.Text = rayMeshResult.ModelHit.ToString()
    HitMeshInfo.Text = rayMeshResult.MeshHit.ToString()
    HitDistanceInfo.Text = rayMeshResult.DistanceToRayOrigin.ToString()
    Vertex1Info.Text = (rayMeshResult.VertexWeight1 * 100) & "%"
    Vertex2Info.Text = (rayMeshResult.VertexWeight2 * 100) & "%"
    Vertex3Info.Text = (rayMeshResult.VertexWeight3 * 100) & "%"
End Sub
