<DIV><FONT face=Arial size=2>Hi</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I have a set of polygons that tile a plane.
Each polygon has a discreet integer value (ie a cell value). I need to rasterize
the plane such that each raster cell contains the dominant discrete value by
area, no interpolation. Also, for any cell in the raster I need
to be able to find what percentage of it's area is occupied by any particular
value. Is there a VTK filter that can do this? If so is it in 3.2 or
must I upgrade (about time anyway).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>If it doesn't exist I'm prepared to write one and
donate the code - can anyone advise on strategy. Perhaps this sort of 2D work is
not appropriate to VTK.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Thanks for any advice</FONT></DIV>
