What’s new in the Aspose.3D for Java 24.2

Release Highlights

Aspose.3D for Java 24.2 introduces native support for InputStream and OutputStream in Scene I/O operations, simplifying integration into Java-based workflows. The release also includes a new API for mesh triangulation and TriMesh streaming, along with important format upgrades and bug fixes across glTF, FBX, USD, and 3MF pipelines.

Enhancements

• Native InputStream/OutputStream Support for Scene I/O
  New overloads allow loading and saving 3D scenes directly via InputStream and OutputStream, streamlining file handling in modern Java apps.

• Improved Handling of Large Vertex OBJ → GLTF Conversions
  Optimized memory and vertex processing to support high-density meshes during OBJ to glTF export.

• .NET 8.0 Support Upgrade
  Internals updated to align with .NET 8.0, ensuring future compatibility for shared cross-platform components.

Bug Fixes

• Skeleton Node Missing Transforms in FBX Export
  Fixed export bug where skeleton nodes had pose data but lacked proper transformation matrices.

• KHR_mesh_quantization in glTF Import
  Added support for the KHR extension to ensure proper attribute decoding during glTF import.

• GLB to FBX Animation Export Fails with Slerp Error
  Resolved failure in quaternion interpolation (slerp) during animation conversion.

• Maya Importer Crash on Unknown Attributes
  Fixed issue where unsupported attributes could terminate the import process.

• USD Load Failure on Invalid Primitive Property
  Prevented loader crash when encountering primitives missing valid property values.

• 3MF External Reference Bug in Build Elements
  Corrected handling of external part references in 3MF build sections.

Public API and Backward Incompatible Changes

• Updated Class: Mesh

  • public Mesh triangulate() — Automatically triangulates non-triangular meshes.

• Updated Class: TriMesh

  • addTriangle(int a, int b, int c) — Allows manual triangle creation.
  • writeVerticesTo(OutputStream stream)
  • write16bIndicesTo(OutputStream stream)
  • write32bIndicesTo(OutputStream stream)

• Updated Class: Scene

  • Numerous fromStream(...), open(...), and save(...) methods added to support Java-native InputStream and OutputStream, with optional format, options, and cancellation token support.
