Encoding 3D Mesh in the Google Draco File

Aspose.3D for Python via .NET API allows developers to import a 3D model, and then encode meshes in the Google Draco files. Developers can also specify the position, texture coordinates, color and normal bits as well as the compression level before encoding a mesh.

Retrieve a 3D Mesh and Encode in Google Draco File

The encode method exposed by the DracoFormat class can be used to encode a 3d mesh in the Google Draco file. It takes a Mesh and DracoSaveOptions objects as parameters. Using the Draco save options, developers can also specify the position, texture coordinates, color and normal bits as well as the compression level before encoding a mesh.

Programming Sample

This code example retrieves a Mesh of Sphere, and then encode in the Google Draco file after specifying a compression level.

from aspose.threed import FileFormat
from aspose.threed.entities import Sphere
from aspose.threed.formats import DracoCompressionLevel, DracoSaveOptions

#  For complete examples and data files, please go to https:# github.com/aspose-3d/Aspose.3D-for-.NET
#  Create a sphere
sphere = Sphere()
options = DracoSaveOptions()
options.compression_level = DracoCompressionLevel.OPTIMAL
#  Encode the sphere to Google Draco raw data using optimal compression level.
b = FileFormat.DRACO.encode(sphere.to_mesh(), options)
#  Save the raw bytes to file
with open("out"  + "SphereMeshtoDRC_Out.drc", "wb") as f:
    f.write(b)
