SDF

SDF field that mesh will be created

Voxel Size

Min Bounds

Position in 3d space that volume will be calculated

Max Bounds

Position in 3d space that volume will be calculated

Bounds Padding

Extends voxels from the bounds

Shade Smooth

Shades mesh smooth

Show Bounds

Shows bounds visualisation that volume will be calculated

SDF Torus

Voxel Size

Size of the voxel

Smoothing

Creates smoother/beveled fracture edges
