Figure 6.40 shows a result of the application of VORONOI to a
geometry which has the shape of the VISTA logo.
Three inner gridpoints labeled 
, 
,
and 
are given in Figure 6.40.
The specified attribute values are 
, 
,
and
.
For this example, VORONOI performed both triangulation and
interpolation (by solving the biharmonic equation),
which led to the solution shown in Figure 6.40
(the shaded quasi-three-dimensional surface) along with the
initial geometry.

singly connected geometry of the VISTA logo.
Attribute values have only been defined
on the three inner grid points , , . All other grid points
are boundary points with interpolated values.
The example shown in Figure 6.40 exceeds the complexity and requirements of current TCAD problems, but it clearly proofs the ability of VORONOI to construct a smooth (``physically reasonable'') interpolation in very complex geometries from a minimum of information required (in this case just three points). VORONOI processes this example in 1.8 CPU seconds (including PIF output) on a PC 486 (DX2, 66Mhz) running Linux 1.0.
