class trimesh.constants.ToleranceMesh(zero: float = 1e-13, merge: float = 1e-08, planar: float = 1e-05, facet_threshold: int = 5000, strict: bool = False)#

Bases: object

ToleranceMesh objects hold tolerance information about meshes.

Parameters:
  • tol.zero (float) – Floating point numbers smaller than this are considered zero

  • tol.merge (float) – When merging vertices, consider vertices closer than this to be the same vertex. Here we use the same value (1e-8) as SolidWorks uses, according to their documentation.

  • tol.planar (float) – The maximum distance from a plane a point can be and still be considered to be on the plane

  • tol.facet_threshold (float) – Threshold for two facets to be considered coplanar

  • tol.strict (bool) – If True, run additional in- process checks (slower)

TolerancePath objects contain tolerance information used in Path objects.

Parameters:
  • tol.zero (float) – Floating point numbers smaller than this are considered zero

  • tol.merge (float) – When merging vertices, consider vertices closer than this to be the same vertex. Here we use the same value (1e-8) as SolidWorks uses, according to their documentation.

  • tol.planar (float) – The maximum distance from a plane a point can be and still be considered to be on the plane

  • tol.seg_frac (float) –

    When simplifying line segments what percentage of the drawing

    scale can a segment be and have a curve fitted

  • tol.seg_angle (float) – When simplifying line segments to arcs, what angle can a segment span to be acceptable.

  • tol.aspect_frac (float) – When simplifying line segments to closed arcs (circles) what percentage can the aspect ratio differfrom 1:1 before escaping the fit early

  • tol.radius_frac (float) – When simplifying line segments to arcs, what percentage of the fit radius can vertices deviate to be acceptable

  • tol.radius_min – When simplifying line segments to arcs, what is the minimum radius multiplied by document scale for an acceptable fit

  • tol.radius_max – When simplifying line segments to arcs, what is the maximum radius multiplied by document scale for an acceptable fit

  • tol.tangent – When simplifying line segments to curves, what is the maximum angle the end sections can deviate from tangent that is acceptable.

trimesh.constants.log_time(method)#

A decorator for methods which will time the method and then emit a log.debug message with the method name and how long it took to execute.
