Syntax
[SG,SGB,SGA]=SGmakedoublefaces([SG,fi,alpha,d,"flip","auxc","auxg"])
Input Parameter
SG: | | Solid geometry; default is sphere (25); |
fi: | | indices of faces to remove; default is 1 |
alpha: | | alpha for separating the feature surfaces; default is .76 |
d: | | displacement in direction of normal vector; |
"flip": | | if used; the orientation of the faces is turned to backwards |
"auxc": | | create auxiliary points along the boundary edge |
"auxg": | | create auxiliary grid points within the feature surface |
Output Parameter
SG: | | SG with removed vertices and removed facets |
SGB: | | Surfaces with displacement |
SGA: | | Surfaces without displacement |
Examples
SGmakedoublefaces(SGsphere(5),[1:30],.76,0,'auxg',.2)
