Ange 3D Filspararalternativ

3D Filspararalternativ

Det finns flera överbelastningar av Scene.save som accepterar ett SaveOptions-objekt. Detta bör vara ett föremål för en klass som härrör från klassen SaveOptions. Varje format spara har en motsvarande klass som innehåller spara alternativ för det spara formatet, till exempel, det finns ColladaSaveOptions för FileFormat.Collada spara formatet.

Användning av Collada Spara inställningarna

Koden nedan visar hur man ställer in sparalternativ innan en 3D-fil sparas till Collada-format.

from aspose.threed.formats import ColladaSaveOptions, ColladaTransformStyle

#  For complete examples and data files, please go to https:# github.com/aspose-3d/Aspose.3D-for-.NET
dataDir = "data-dir"
saveColladaopts = ColladaSaveOptions()
#  Generates indented XML document
saveColladaopts.indented = True
#  The style of node transformation

#  Configure the lookup paths to allow importer to find external dependencies.
saveColladaopts.lookup_paths = [[dataDir]]

Spara beroenden för en 3D i det verkliga filsystemet

Utvecklare kan behöva spara alla 3D-scener i det riktiga filsystemet. De kan definiera sökvägen för en lokal katalog, spara i MemoryFileSystem-objektet eller helt enkelt förkasta beroenden. Egenskapen FileSystem läggs till i alla spara alternativklasser.
