Block Collision Box Util

dev.anvilcraft.lib.v2.util.ShapeUtil provides merging, cutting, rotation, and mirroring of block collision boxes ( VoxelShape).

Single-threaded Operations

• merge(VoxelShape...) / merge(AABB...) – merges multiple shapes (OR operation)
• cut(VoxelShape base, VoxelShape... cutters) – cuts cutters from the base shape
• cut(AABB base, AABB... cutters) – same as above, with AABB input
• rotate(Direction.Axis, float angle, VoxelShape) – rotates shapes (counterclockwise)
• rotate(Direction.Axis, float angle, AABB...) – rotates collision boxes (16-pixel coordinate system)
• mirror(Direction.Axis, VoxelShape) / mirror(Direction.Axis, AABB...) – mirrors

Multi-threaded Merging

threadedJoin(List<VoxelShape>, BooleanOp, ExecutorService) – merges a large number of shapes in batched parallel operations, returns Future<VoxelShape>, suitable for use during initialization.

Helper Methods

• box(AABB) – converts a 16x16 AABB to a VoxelShape (equivalent to Block.box(...))
