public sealed class RayMeshGeometry3DHitTestResult : RayHitTestResult

The RayMeshGeometry3DHitTestResult type exposes the following members.

  NameDescription
Public propertyDistanceToRayOriginGets the distance between the point of intersection and the ray's origin in the coordinate space of Visual3D which initiated the hit test. (Overrides RayHitTestResult.DistanceToRayOrigin.)
Public propertyMeshHitGets the MeshGeometry3D intersected by this hit test.
Public propertyModelHitGets the Model3D intersected by the ray along which the hit test was performed. (Inherited from RayHitTestResult.)
Public propertyPointHitGets the point at which the mesh was intersected by the ray along which the hit test was performed. (Overrides RayHitTestResult.PointHit.)
Public propertyVertexIndex1First vertex of the mesh triangle intersected by the ray.
Public propertyVertexIndex2Second vertex of the mesh triangle intersected by the ray.
Public propertyVertexIndex3Third vertex of the mesh triangle intersected by the ray.
Public propertyVertexWeight1Relative contribution of the first vertex of a mesh triangle to the point at which that triangle was intersected by the hit test, expressed as a value between zero and 1.
Public propertyVertexWeight2Relative contribution of the second vertex of a mesh triangle to the point at which that triangle was intersected by the hit test, expressed as a value between zero and 1.
Public propertyVertexWeight3Relative contribution of the third vertex of a mesh triangle to the point at which that triangle was intersected by the hit test, expressed as a value between zero and 1.
Public propertyVisualHitGets the Visual intersected by the ray along which the hit test was performed. (Inherited from RayHitTestResult.)

  NameDescription
Public methodEquals(Object)Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Protected methodFinalizeAllows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Public methodGetHashCodeServes as a hash function for a particular type. (Inherited from Object.)
Public methodGetTypeGets the Type of the current instance. (Inherited from Object.)
Protected methodMemberwiseCloneCreates a shallow copy of the current Object. (Inherited from Object.)
Public methodToStringReturns a string that represents the current object. (Inherited from Object.)

This class returns information about the intersection of a ray and a MeshGeometry3D.

Barycentric coordinates returned by VertexWeight1, VertexWeight2, and VertexWeight3 can be interpolated to find the Point3D where the intersection occurred, or the point on the intersected model's texture using texture coordinates.
