3D reference map · First 3D picture

value
cut-mesh3d : procedure?

Cuts a mesh by one declared plane and returns the clipped halves, section, and optional caps.

value
clip-planes3d : procedure?

Applies ordered render-only plane clips to a spatial visual.

value
clip-box3d : procedure?

Applies a render-only axis-aligned box clip to a spatial visual.

value
section-fill3d : procedure?

Builds a visible cap-style mesh for a section.

value
section-hatch3d : procedure?

Builds deterministic hatch strokes in a section’s local plane basis.

value
section3d-area : procedure?

Measures the signed-area-normalized section region under the documented validity policy.

value
section3d-centroid : procedure?

Returns the centroid of a measurable section region.

value
section3d-perimeter : procedure?

Returns the perimeter of a measurable section region.

procedure
(section3d-settings? value) → boolean?
value : any/c

Recognizes the immutable numerical policy used by section and cut operations.

value
slice-stack3d : procedure?

Builds stable section groups for an ordered stack of planes.

value
prepare-cross-section-function3d : procedure?

Prepares an immutable table of sampled cross sections and measurements.

value
volume-by-slices3d : procedure?

Estimates volume from a prepared cross-section table with an explicit quadrature rule.
