Load and Save Options — Aspose.3D FOSS for Java

Overview

Load and save options are passed to Scene.open() (load) or Scene.save() (save) to control format-specific behaviour such as axis flipping, scale, coordinate conventions, and binary vs. ASCII output.

Package: com.aspose.threed

All option classes inherit from LoadOptions or SaveOptions.

Base Classes

Class	Description
`LoadOptions`	Abstract base for all format-specific load-option objects. Provides `setFlipCoordinateSystem()` and `setScale()`.
`SaveOptions`	Abstract base for all format-specific save-option objects. Provides `setFlipCoordinateSystem()` and `setAxisSystem()`.

OBJ Format

Class	Description
`ObjLoadOptions`	Load options for Wavefront OBJ. Key properties: `setFlipCoordinateSystem()`, `setScale()`, `setEnableMaterials()`, `setNormalizeNormal()`.
`ObjSaveOptions`	Save options for Wavefront OBJ. Controls normals, UVs, material references, and point-cloud mode.

STL Format

Class	Description
`StlLoadOptions`	Load options for STL. Supports `setFlipCoordinateSystem()`, `setRecalculateNormal()`, and `setContentType()`.
`StlSaveOptions`	Save options for STL. Controls `setFlipCoordinateSystem()`, `setAxisSystem()`, and `setContentType()`.

glTF Format

Class	Description
`GltfLoadOptions`	Load options for glTF 2.0 and GLB. Key properties: `setFlipCoordinateSystem()`, `setPrettyPrint()`.
`GltfSaveOptions`	Save options for glTF 2.0 and GLB. Use `setContentType(FileContentType.BINARY)` to produce a self-contained `.glb` package.

FBX Format

Class	Description
`FbxLoadOptions`	Load options for FBX. Key property: `setFlipCoordinateSystem()`.
`FbxSaveOptions`	Save options for FBX.

Quick Example

import com.aspose.threed.Scene;
import com.aspose.threed.GltfSaveOptions;
import com.aspose.threed.FileContentType;

Scene scene = Scene.fromFile("model.obj");

// Save as binary GLB
GltfSaveOptions opts = new GltfSaveOptions();
opts.setContentType(FileContentType.BINARY);
scene.save("output.glb", opts);
