A General Extrusion coupling operator (
) maps an expression defined on a source to an expression that can be evaluated on any destination geometry where the destination map expressions are valid. Compared to the
linear extrusion, these operators define a more general, possibly nonlinear, relation between source and destination. Specifically, when the destination has more space dimensions than the source, the operator performs extrusion of values. The default
Operator name is
genext1.
Specify the general extrusion destination map by entering an expression in the x-expression,
y-expression, and
z-expression fields. This maps each point in the destination to a point in the intermediate mesh, where the argument of the extrusion operator is evaluated. A general extrusion operator can be evaluated at any point where the destination map expressions are defined.
