VoxLib

VoxLib 1.6.1

A targeted performance and memory update that preserves VoxLib’s existing public API and exact voxel-shape behavior.

Improved

• Added specialized identity-based caching for repeated unions and transformations.
• Reduced allocation on cached transformations and repeated shape operations.
• Reduced temporary allocation when simplifying large shapes. In the measured 256-box benchmark, allocation dropped from approximately 10.9 MB to 1.9 MB per operation.
• Reduced union and rotation overhead by avoiding unnecessary collections and temporary coordinate arrays.
• Added lazy memoization for finite CommonShapes factories.
• Canonicalized chairs without backrests, reducing the number of possible memoized common-shape instances.
• Improved cache admission for interleaved repeated binary unions.
• Centralized Minecraft 1.19.4-specific shape operations to make future version ports easier.

Tooling and verification

• Added a reproducible JMH benchmark suite with vanilla and legacy implementation comparisons.
• Added exact occupied-volume and JVM API compatibility coverage.
• Verified union, transformation, caching, common-shape, and simplifier behavior.

Compatibility

• Minecraft 1.19.4
• Fabric
• Java 17 or newer
• No public API changes
• Existing source and binary usage remains compatible

VoxLib remains convenience-first. Fixed shapes should still normally be created once and stored as constants.
