Save a 3D Scene in the PDF

The Scene class of the Aspose.3D API represents a 3D scene. Developers can build a 3D scene by adding Camera, Light, polygons and various other entities. They can also now save a 3D scene in the PDF file format.

Aspose.3D for Python via .NET directly writes the information about the API and Version Number in output documents. For example, upon rendering a Drawing to PDF, Aspose.3D for Python via .NET populates Application field with value ‘Aspose.3D’ and PDF Producer field with value, e.g ‘Aspose.3D 17.9’.

Please note that you cannot instruct Aspose.Diagram for Python via .NET API to change or remove this information from output Documents.

Create a 3D PDF with a Cylinder, and Rendered in Shaded Illustration Mode with CAD Optimized Lighting

The Save method of the Scene class allows to save a 3D scene in the PDF format. Developers may load any 3D supported file or build a new 3D scene, they can save a 3D scene in the PDF format as shown in this code example:

from aspose.threed import Scene
from aspose.threed.entities import Cylinder
from aspose.threed.shading import PhongMaterial
from aspose.threed.formats import PdfSaveOptions, PdfLightingScheme, PdfRenderMode
# Create a new scene
scene = Scene()
# Create a cylinder child node
cylinder = scene.root_node.create_child_node("cylinder", Cylinder())
cylinder.material = PhongMaterial()
# Set rendering mode and lighting scheme
opt = PdfSaveOptions()
opt.lighting_scheme = PdfLightingScheme.CAD
opt.render_mode = PdfRenderMode.SHADED_ILLUSTRATION
# Save in the PDF format
scene.save("output_out.pdf", opt)
