]split_mesh(, mesh, policy)
Split mesh into sub-meshes by VertexElementMaterial.
Each sub-mesh will use only one material.
The original mesh will not get changed.
Returns
New splitted meshes
@staticmethod
def split_mesh(mesh, policy):
...
| Parameter | Type | Description |
|---|---|---|
| mesh | aspose.threed.entities.Mesh | |
| policy | aspose.threed.entities.SplitMeshPolicy |
Example
The following code shows how to split a box into sub meshes using material indices.
from aspose import pycore
from aspose.threed.entities import Box, MappingMode, PolygonModifier, ReferenceMode, SplitMeshPolicy, VertexElementMaterial, VertexElementType
# Create a mesh of box(A box is composed by 6 planes)
box = Box().to_mesh()
# Create a material element on this mesh
mat = pycore.cast(VertexElementMaterial, box.create_element(VertexElementType.MATERIAL, MappingMode.POLYGON, ReferenceMode.INDEX))
# And specify different material index for each plane
mat.indices.extend([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.
planes = PolygonModifier.split_mesh(box, SplitMeshPolicy.CLONE_DATA)
# 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.extend([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.split_mesh(box, SplitMeshPolicy.COMPACT_DATA)
split_mesh(, scene, policy, remove_old_mesh)
Split mesh into sub-meshes by VertexElementMaterial.
Each sub-mesh will use only one material.
Perform mesh splitting on all nodes of the scene.
@staticmethod
def split_mesh(scene, policy, remove_old_mesh):
...
| Parameter | Type | Description |
|---|---|---|
| scene | aspose.threed.Scene | |
| policy | aspose.threed.entities.SplitMeshPolicy | |
| remove_old_mesh | bool |

planes = PolygonModifier.split_mesh(box, SplitMeshPolicy.COMPACT_DATA)
split_mesh(, node, policy, create_child_nodes, remove_old_mesh)
Split mesh into sub-meshes by VertexElementMaterial.
Each sub-mesh will use only one material.
Perform mesh splitting on a node
@staticmethod
def split_mesh(node, policy, create_child_nodes, remove_old_mesh):
...
| Parameter | Type | Description |
|---|---|---|
| node | aspose.threed.Node | |
| policy | aspose.threed.entities.SplitMeshPolicy | |
| create_child_nodes | bool | Create child nodes for each sub-mesh. |
| remove_old_mesh | bool | Remove the old mesh after split, if this parameter is false, the old and new meshes will co-exists. |
