aabbOverlap#

const aabbOverlap: (a, b) => boolean = wasm.collision_aabb_overlap

The prefilter on its own: strict overlap on all three axes, so exactly touching boxes are NOT a candidate pair.

Parameters#

a#

Float64Array

b#

Float64Array

Returns#

boolean

findClashes#

const findClashes: (parts_json, options_json) => string = wasm.collision_find_clashes

Two-phase clash detection over a placed part list. parts_json is [{ id, document, matrix? }], options_json a partial { minimumOverlapVolume?, ignorePairs? } ("{}" for the defaults). Returns [{ partA, partB, overlapBoundingBox: [min(3), max(3)] }].

The confirmed overlap SOLID does not cross: it lives in the arena this call builds and dies with it. A caller that needs the overlap geometry rebuilds it with brep_boolean_intersect on the reported pair — which is the same boolean this ran, on the same two solids.

Parameters#

parts_json#

string

options_json#

string

Returns#

string
