Struct SdfOffsetParams 

pub struct SdfOffsetParams {
    pub voxel_size_mm: f64,
    pub padding_mm: f64,
    pub max_voxels: usize,
    pub offset_neighbors: usize,
    pub adaptive_resolution: bool,
    pub coarse_voxel_multiplier: f64,
    pub refinement_distance_mm: f64,
    pub use_gpu: bool,
}

Parameters for SDF offset operation.

Fields

voxel_size_mm: f64

Voxel size in mm (smaller = more detail, more memory). When adaptive_resolution is true, this is the fine voxel size.

padding_mm: f64

Padding beyond mesh bounds in mm.

max_voxels: usize

Maximum number of voxels before error (memory safety).

offset_neighbors: usize

Number of nearest neighbors for offset interpolation.

adaptive_resolution: bool

Enable adaptive multi-resolution SDF for memory efficiency. When true, uses coarse voxels far from the surface and fine voxels near it.

coarse_voxel_multiplier: f64

Coarse voxel size multiplier (relative to voxel_size_mm). Only used when adaptive_resolution is true. Default: 4.0 (coarse voxels are 4x larger than fine voxels).

refinement_distance_mm: f64

Distance from surface (in mm) within which to use fine voxels. Only used when adaptive_resolution is true. Default: 5.0mm

use_gpu: bool

Use GPU acceleration if available (requires gpu feature). When enabled and a GPU is available, SDF computation will use GPU compute shaders for significant speedup on large meshes. Falls back to CPU if GPU is unavailable or initialization fails.

Implementations

impl SdfOffsetParams

pub fn adaptive() -> Self

Create params with adaptive resolution enabled for large meshes.

Uses coarser voxels far from the surface to reduce memory usage while maintaining detail quality near the surface.

pub fn adaptive_high_quality() -> Self

Create high-quality params with adaptive resolution.

pub fn adaptive_large_mesh() -> Self

Create params optimized for very large meshes.

pub fn with_gpu(self) -> Self

Create params with GPU acceleration enabled.

Requires the gpu feature to be enabled. Falls back to CPU automatically if no GPU is available.

pub fn coarse_voxel_size_mm(&self) -> f64

Get the coarse voxel size when adaptive resolution is enabled.

Trait Implementations

impl Clone for SdfOffsetParams

fn clone(&self) -> SdfOffsetParams

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SdfOffsetParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SdfOffsetParams

fn default() -> Self

Returns the “default value” for a type.
