lattice envelope vol
lattice envelope vol(id)
Returns the lattice coefficients of the envelope of volume id.
lattice envelope vol(id)=num,c,z
Changes these coefficients.
lattice fac vol
lattice fac(f) vol(id)
Returns the lattices of facet f of volume id.
lattice fac(f) vol(id)=t,c,z,ext,coe,flag,atten
Changes these parameters.
t=number of the volume replacing each chaque side of the facet.
z=multiplier along the edge.
ext,coe,flag=extension curve coefficient.
atten=attenuation coefficient of the thickness of the lattice.
Returns the lattice of volume id.
Changes this lattice.
1) If volume numbert t is build in a bounding cube of side 256
and if si z==1, the lattice will adjuste exactly to the length of the edge.
2) In the case of a lattice facet, if atten = 0, this coefficient will be set to 1 by default.
If close fac(f) vol(id)=0, the facet will not be closed (closed by default).
3) It is necessary to do yes lattice to activate the lattices.
4) To assign multiple lattice to one facet or to a unique volume, the volume must be duplicated with a single lattice.
