NameDescription
System_CAPS_pubpropertyDistanceToRayOrigin

Gets 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.)

System_CAPS_pubpropertyMeshHit

Gets the MeshGeometry3D intersected by this hit test.

System_CAPS_pubpropertyModelHit

Gets the Model3D intersected by the ray along which the hit test was performed.(Inherited from RayHitTestResult.)

System_CAPS_pubpropertyPointHit

Gets the point at which the mesh was intersected by the ray along which the hit test was performed.(Overrides RayHitTestResult.PointHit.)

System_CAPS_pubpropertyVertexIndex1

First vertex of the mesh triangle intersected by the ray.

System_CAPS_pubpropertyVertexIndex2

Second vertex of the mesh triangle intersected by the ray.

System_CAPS_pubpropertyVertexIndex3

Third vertex of the mesh triangle intersected by the ray.

System_CAPS_pubpropertyVertexWeight1

Relative 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.

System_CAPS_pubpropertyVertexWeight2

Relative 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.

System_CAPS_pubpropertyVertexWeight3

Relative 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.

System_CAPS_pubpropertyVisualHit

Gets the Visual intersected by the ray along which the hit test was performed.(Inherited from RayHitTestResult.)

NameDescription
System_CAPS_pubmethodEquals(Object)

Determines whether the specified object is equal to the current object.(Inherited from Object.)

System_CAPS_pubmethodGetHashCode()

Serves as the default hash function. (Inherited from Object.)

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodToString()

Returns 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.
