Functions

approximate_volume

Compute the approximate volume enclosed by the zero level-set.

count_interior_cells

Count the number of cells where the SDF is negative (inside the surface).

evaluate_sdf_batch

Evaluate an SDF at a batch of query points.

fast_sweeping_update

One pass of the fast sweeping method.

gradient_sdf_batch

Compute the SDF gradient at a batch of query points.

intersection_sdf

Compute the intersection of two SDFs: max(a, b) pointwise.

marching_cubes

Extract a triangle mesh from the SDF grid at the given isovalue using the marching cubes algorithm (simplified 3-case variant).

mesh_to_sdf

Convert a triangle mesh to an SDF by computing the distance from each grid cell to the nearest triangle.

mesh_triangle_count

Count the number of triangles in the extracted mesh.

sdf_close

SDF morphological closing: dilate then erode.

sdf_dilate

SDF dilation: offset the surface outward by offset units.

sdf_erode

SDF erosion: offset the surface inward by offset units.

sdf_gaussian_blur

Apply a 3×3×3 box-filter (Gaussian-like) convolution to an SDF grid.

sdf_laplacian_sharpen

Laplacian (sharpening) convolution on the SDF.

sdf_laplacian_smooth

Iterative Laplacian smoothing of the SDF.

sdf_mean_curvature_smooth

Mean-curvature smoothing of the SDF (simplified).

sdf_offset_surface

Signed distance field offset: produce an iso-surface at offset.

sdf_open

SDF morphological opening: erode then dilate.

shell_sdf

Compute the shell SDF: |sdf(p)| - thickness/2.

smooth_union_sdf

Smooth union of two SDFs using polynomial smoothing.

sphere_trace

Perform sphere tracing (ray marching) against an SDF grid.

subtraction_sdf

Compute the subtraction of SDF b from SDF a: max(a, -b) pointwise.

union_sdf

Compute the union of two SDFs: min(a, b) pointwise.
