Planar | |
PlanarShadowMeshCreator is a class that can be used to create a planar shadow mesh.
This is a mesh that is created by squishing the SceneNodes specified in the OriginalGroupNode to the specified plane.
The squished mesh has zero height. The mesh can be used to create MeshModelNode that shows the shadow.

public class PlanarShadowMeshCreator
The PlanarShadowMeshCreator type exposes the following members.
Constructors| Name | Description | |
|---|---|---|
 | PlanarShadowMeshCreator(GroupNode) | Constructor |
| PlanarShadowMeshCreator(StandardMesh) | Constructor |
Properties| Name | Description | |
|---|---|---|
 | ClipToPlane | Gets or sets a boolean that specifies if the shadow mesh is clipped to the plane's edge. Default value is true. |
| OriginalGroupNode | Gets the GroupNode that was used to create the planar shadow mesh (set when PlanarShadowMeshCreator is created from a GroupNode). |
| OriginalMesh | Gets the StandardMesh that was used to create the planar shadow mesh (set when PlanarShadowMeshCreator is created from a StandardMesh). |
| ShadowMesh | ShadowMesh gets the StandardMesh that represents a show geometry that was generated after calling ApplyDirectionalLight(Vector3), ApplyPointLight(Vector3) or ApplyShadowMatrix(Matrix4x4). |
| SimplifyNormalCalculation | When true (by default) then the normals for the generated shadow mesh will be all set to the normal of the plane. This is faster, but when the shadow is shown by both front and back material this may produce some z-fighting artifacts because the triangles that are pointer down will still have the same normal as triangles that are pointed up. This can be solved by setting this property to false and this will calculate the actual normals for the mesh. |
Methods| Name | Description | |
|---|---|---|
| ApplyDirectionalLight | ApplyShadowMatrix method updates the ShadowMesh with the specified directional light's direction Vector3. The created shadow mesh can be read from ShadowMesh. |
| ApplyPointLight | ApplyShadowMatrix method updates the ShadowMesh with the specified point light's position. The created shadow mesh can be read from ShadowMesh. |
| ApplyShadowMatrix | ApplyShadowMatrix method updates the shadow mesh with the specified shadow matrix. The created shadow mesh can be read from ShadowMesh. |
| SetPlane(PlaneModelNode) | SetPlane method sets the plane for the shadow mesh from the specified PlaneModelNode. |
| SetPlane(Vector3, Vector3, Vector3, Vector2) | SetPlane method sets the plane for the shadow mesh from the specified plane information. |
| UpdateGroupNode | UpdateGroupNode must be called when the GroupNode that was used to create this PlanarShadowMeshCreator was changed. |
| UpdateMesh | UpdateMesh must be called when the StandardMesh that was used to create this PlanarShadowMeshCreator was changed. |
