]from_mesh(, declaration, mesh)
Create a TriMesh from given mesh object with given vertex layout.
Returns
Instance of TriMesh converted from input mesh with specified vertex’s memory layout
@staticmethod
def from_mesh(declaration, mesh):
...
| Parameter | Type | Description |
|---|---|---|
| declaration | aspose.threed.utilities.VertexDeclaration | Vertex’s type definition, or memory layout |
| mesh | Mesh | Source mesh |
Example
The following code shows how to create a TriMesh with custom memory layout, and export it to file.
from aspose.threed.entities import Sphere, TriMesh
from aspose.threed.utilities import VertexDeclaration, VertexFieldDataType, VertexFieldSemantic
# Define a vertex declaration as {FVector3 Position; FVector3 Normal; FVector2 UV}
vd = VertexDeclaration()
vd.add_field(VertexFieldDataType.F_VECTOR3, VertexFieldSemantic.POSITION)
vd.add_field(VertexFieldDataType.F_VECTOR3, VertexFieldSemantic.NORMAL)
vd.add_field(VertexFieldDataType.F_VECTOR2, VertexFieldSemantic.UV)
# convert a mesh to tri-mesh using specified memory layout
mesh = Sphere().to_mesh()
triMesh = TriMesh.from_mesh(vd, mesh)
# save it to a stream, 115 vertices * 32bytes per vertex
with open("output.bin", "wb") as stream:
triMesh.write_vertices_to(stream)
# save indices as ushort to stream, 504 indices * 2 bytes per index
triMesh.write_16b_indices_to(stream)
from_mesh(, mesh, use_float)
Create a TriMesh from given mesh object, the vertex declaration are based on the input mesh’s structure.
Returns
The TriMesh generated from given Mesh
@staticmethod
def from_mesh(mesh, use_float):
...
| Parameter | Type | Description |
|---|---|---|
| mesh | Mesh | |
| use_float | bool | Use float type instead of double type for each vertex element component. |
