geomcsg
g = geomcsg(sl,pl,...) decomposes the 1D solid objects sl and the 1D point
objects pl into the analyzed 1D geometry g.
[g,st] = geomcsg(sl) additionally returns a solid table, st, that relates the
original solid objects in sl to the subdomains in g.
[g,st,ft] = geomcsg(sl,fl,...) additionally returns a face table, ft, that
relates the original face objects in fl to the face segments in g.
[g,st,ft,ct] = geomcsg(sl,fl,cl,...) additionally returns the curve table,
ct, that relates curve objects in cl to edge segments in g.
[g,st,ft,ct,pt] = geomcsg(sl,fl,cl,pl,...) additionally returns the point
table, pt, that relates point objects in pl to vertices in g.
[g,ct] = geomcsg(sl,cl,...) additionally returns the curve table, ct, for 2D
geometry objects.
[g,ct,pt] = geomcsg(sl,cl,pl,...) additionally returns the point table, pt,
for 2D geometry objects.
[g,pt] = geomcsg(sl,pl,...) additionally returns the point table, pt, for 1D
geometry objects.
sl, fl, cl, and pl are cell arrays containing the geometry objects of different types.
st, ft, ct, and pt are matrices where each row corresponds to the number of the
corresponding geometric entity in g, and each row corresponds to the object with
the same index in sl, fl, cl, and pl, respectively.
The function geomcsg accepts the following property/values:
