Description
(Virtuoso Photonics Option) Returns a list of new surface shapes derived from the areas of shapes of the first input argument g_shapes1 that do not overlap any areas of shapes of the second input argument g_shapes2.
Arguments
|
g_shapes1
|
o_shape | (l_shapes...)
A shape or a list of shapes of the first input argument.
|
|
g_shapes2
|
o_shape | (l_shapes...)
A shape or a list of shapes of the second input argument.
|
|
?cellView d_cellViewId
|
|
|
A cellview ID in which output shapes are created. If not specified, output shapes are created in the cellview of the first shape of the first input argument g_shapes1.
|
|
?lpp l_lpp
|
|
|
tx_layer | (tx_layer tx_purpose)
A layer-purpose pair in the given cellview on which output shapes are created. If not specified, output shapes are created on the layer-purpose pair of the first shape of the first input argument g_shapes1.
|
|
?facetsToCurves t | nil
|
|
|
Specifies whether all input facets are converted to curves before the actual operation.
The default is nil, which means that the input facets are not converted to curves.
|
Value Returned
|
l_surface
|
List of resulting surface shapes.
|
|
nil
|
Returns an empty list.

Example
c=ccCreateCurve("3*cos(t)" "3*sin(t)" 0:8*atan(1))
=> cc@0x36adc1b
s1=ccCreateSurface(cvId "y0" ccCreatePolyCurve(list(c list(0:2 0)) ?close t))
=> cc@0x2d609190
s2=ccCreateSurface(cvId "y0" ccCreatePolyCurve(list(c list(-sqrt(3):-1 0)) ?close t))
=> cc@0x20480bc0
s3=ccCreateSurface(cvId "y0" ccCreatePolyCurve(list(c list(sqrt(3):-1 0)) ?close t))
=> cc@0x29143150
s=ccLayerAndNot(s1 list(s2 s3))
=> (cc@0x27eeea10)
