What's New in v3.1.0

Version 3.1.0 is a major update to Koru, introducing real-time physics simulation, a brand-new object alignment tool, improved geometry optimization, and expanded 3D format support with FBX animations.

Real-Time Physics Simulation

A new interactive physics tool allows you to run real-time gravity simulations and naturally position objects in your scene:

• New Physics Tool: Easily start and stop live physics simulations directly from the toolbar.
• Gravity & Collisions: Run simulations for chosen dynamic objects, allowing them to fall under gravity and collide realistically with the scene.
• Interactive Dragging: Click and drag objects around in real time with the mouse to toss, drop, or guide them into natural arrangements.
• Keyboard Controls: The selected dynamic object can also be moved using keyboard keys for precise positioning during simulation.

Fast & Accurate Mesh Optimization

Work freely with models of any complexity and level of detail — the upgraded optimization tool effortlessly simplifies ultra-dense geometry to acceptable quality without corrupting texture coordinates:

• Handle Any Complexity: Use 3D models of arbitrary detail; the tool reduces heavy geometry down to web-friendly sizes while keeping UV texture mapping fully intact.
• High-Fidelity Simplification: Upgraded reduction algorithm produces clean topology and preserves fine silhouette details.
• Intuitive Distortion Control: Set a target shape distortion limit rather than guessing vertex counts, ensuring your models keep their exact shape.
• Live Mesh Statistics: View original and reduced vertex and triangle counts directly in the optimization dialog.
• Animated Mesh Support: Support for skinned and animated models when reducing geometry and baking lightmaps.

Object Alignment Tool

A dedicated tool for quickly arranging and organizing multiple objects in 3D space:

• Precise Alignment: Line up objects along any 3D axis by their edges, centers, or pivot points.
• Even Distribution: Spread items out with consistent spacing to easily create neat rows, shelves, or displays.
• Flexible Placement: Align objects relative to each other, the center of the scene, or the camera view.
• Orientation Matching: Instantly reset or synchronize rotations across all selected objects.

Expanded 3D Formats & Animations

Broader compatibility and smoother asset importing:

• Modern FBX & GLTF Import: Faster, more reliable import for FBX and GLTF/GLB models.
• FBX Animations: Support for importing and playing animations from FBX files.

System Requirements

• WebGL support (all modern browsers)
• At least 4 GB RAM (8 GB recommended)
• 250 MB free disk space
• Internet connection for activation and updates
