from_raw_data method

from_raw_data(, vd, vertices, indices, generate_vertex_mapping)

Create TriMesh from raw data

Returns

The TriMesh instance that encapsulated the input byte array.

@staticmethod
def from_raw_data(vd, vertices, indices, generate_vertex_mapping):
    ...

Parameter	Type	Description
vd	aspose.threed.utilities.VertexDeclaration	Vertex declaration, must contains at least one field.
vertices	bytes	The input vertex data, the minimum length of the vertices must be greater or equal to vertex declaration’s size
indices	list	The triangle indices
generate_vertex_mapping	bool	Generate Vertex for each vertex, which is not necessary for just serialization/deserialization.

Remarks

The returned TriMesh will not copy the input byte array for performance, external changes on the array will be reflected to this instance.

Example

The following code shows how to construct a TriMesh from raw bytes, this is useful when build your own 3D format

from aspose.threed.entities import TriMesh
from aspose.threed.utilities import VertexDeclaration, VertexFieldDataType, VertexFieldSemantic

indices = [0, 1, 2 ]
vertices = [                0, 0, 0, 191,                 0, 0, 0, 0,                 0, 0, 0, 191,                 0, 0, 0, 191,                 0, 0, 0, 0,                 0, 0, 0, 63,                 0, 0, 0, 63,                 0, 0, 0, 0,                 0, 0, 0, 63
]
vd = VertexDeclaration()
vd.add_field(VertexFieldDataType.F_VECTOR3, VertexFieldSemantic.POSITION)
triMesh = TriMesh.from_raw_data(vd, vertices, indices, True)
