Detailed Description

Options for compute_local_feature_size().

Member Data Documentation

ray_offset

float ray_offset = 1e-4f

Ray offset along the vertex normal to avoid self-intersection (relative to bounding box diagonal).

The actual offset distance is ray_offset * bbox_diagonal. Set to 0 to disable offset (not recommended).

default_lfs

float default_lfs = std::numeric_limits<float>::infinity()

Default local feature size value used when raycasting fails to find valid hits.

Default: infinity.

medial_axis_tolerance

float medial_axis_tolerance = 1e-4f

Error tolerance for medial axis binary search convergence (relative to bounding box diagonal).

The binary search stops when |distance_to_surface - depth_along_ray| < tolerance * bbox_diagonal. Smaller values produce more accurate results but require more iterations. Default: 1e-4 (0.01% of bounding box diagonal).
