What’s new in the Aspose.3D for Java 24.1

Release Highlights

Aspose.3D for Java 24.1 introduces advanced animation and file format enhancements, including full support for quaternion-based and Euler-based animations in FBX and glTF. The release also improves 3MF format handling for assembled structures and resolves a wide range of compatibility and data integrity issues in USDZ, JT, and glTF workflows.

New Features

• Quaternion-Based Animation Export
  Now supports exporting animations driven by quaternion rotation to both FBX and glTF formats, enhancing smooth rotational transitions.

• Keyframe Access via AnimationChannel
  New getKeyframeSequence() API provides a unified interface to retrieve or set keyframe sequences for animation channels.

Enhancements

• Convert Euler to Quaternion Animation
  Internal updates allow converting Euler angle-based animations to quaternion format.

• Improved GLTF Animation Export
  Both Euler and quaternion-based rotation animations can now be reliably exported to glTF format.

• 3MF Assembled Structure Support
  Added support for exporting 3MF files that include hierarchical assemblies, increasing compatibility with 3D printing platforms.

• Keyframe Resampling for Accurate Conversion
  Enhanced animation conversion pipeline now resamples keyframes when transitioning from quaternion to Euler format.

Bug Fixes

• JT 8.0 File Load Failure
  Resolved inability to load .JT files from version 8.0 into scenes.

• NaN Quaternion Rotations
  Fixed quaternion calculation bug that could result in NaN rotation values.

• Corrupted Texture Coordinates in GLTF
  Addressed data corruption issue when resaving glTF models with textures.

• Undetected GLTF Formats
  Improved format detection logic for edge-case glTF files.

• Exception on Incomplete Keyframe Sequences in GLTF
  Prevented export crashes due to missing or incomplete keyframe sequences.

• USDZ/GLTF Export Fails for Negative Material Index
  Fixed an issue where meshes with negative material indices failed during export.

• USDZ Infinity Value Handling
  Exporter now safely handles -inf and inf values in USDZ format.

• USDZ Incompatibility with THREE.js Exporter
  Enhanced parser to correctly open USDZ files generated by THREE.js tools.

Public API and Backward Incompatible Changes

• Updated Class: AnimationChannel

  • getKeyframeSequence() / setKeyframeSequence(KeyframeSequence)
    • Provides structured access to animation keyframe sequences. Existing interfaces will be deprecated in the future.

• Updated Class: Quaternion

  • public static Quaternion slerp(double t, Quaternion v1, Quaternion v2)
    • Adds support for spherical linear interpolation between quaternions (SLERP).
