]SplitMesh(Node, SplitMeshPolicy, bool, bool)
Split mesh into sub-meshes by VertexElementMaterial. Each sub-mesh will use only one material. Perform mesh splitting on a node
public static void SplitMesh(Node node, SplitMeshPolicy policy, bool createChildNodes = false,
bool removeOldMesh = true)
| Parameter | Type | Description |
|---|---|---|
| node | Node | |
| policy | SplitMeshPolicy | |
| createChildNodes | Boolean | Create child nodes for each sub-mesh. |
| removeOldMesh | Boolean | Remove the old mesh after split, if this parameter is false, the old and new meshes will co-exists. |
Examples
The following code shows how to split a box into sub meshes using material indices.
// Create a mesh of box(A box is composed by 6 planes)
Mesh box = (new Box()).ToMesh();
// Create a material element on this mesh
VertexElementMaterial mat = (VertexElementMaterial)box.CreateElement(VertexElementType.Material, MappingMode.Polygon, ReferenceMode.Index);
// And specify different material index for each plane
mat.Indices.AddRange(new int[] { 0, 1, 2, 3, 4, 5 });
// Now split it into 6 sub meshes, we specified 6 different materials on each plane, each plane will become a sub mesh.
// We used the CloneData policy, each plane will has the same control point information or control point-based vertex element information.
Mesh[] planes = PolygonModifier.SplitMesh(box, SplitMeshPolicy.CloneData);
// Now split it into 2 sub meshes, first mesh will contains 0/1/2 planes, and second mesh will contains the 3/4/5th planes.
mat.Indices.Clear();
mat.Indices.AddRange(new int[] { 0, 0, 0, 1, 1, 1 });
// We used the CompactData policy, each plane will has its own control point information or control point-based vertex element information.
planes = PolygonModifier.SplitMesh(box, SplitMeshPolicy.CompactData);

SplitMesh(Scene, SplitMeshPolicy, bool)
Split mesh into sub-meshes by VertexElementMaterial. Each sub-mesh will use only one material. Perform mesh splitting on all nodes of the scene.
public static void SplitMesh(Scene scene, SplitMeshPolicy policy, bool removeOldMesh = true)
| Parameter | Type | Description |
|---|---|---|
| scene | Scene | |
| policy | SplitMeshPolicy | |
| removeOldMesh | Boolean |

SplitMesh(Mesh, SplitMeshPolicy)
Split mesh into sub-meshes by VertexElementMaterial. Each sub-mesh will use only one material. The original mesh will not get changed.
public static Mesh[] SplitMesh(Mesh mesh, SplitMeshPolicy policy)
Return Value
New splitted meshes
