<DIV><FONT face=Arial size=2>Hi VTK users,</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>This is my first excursion into VTK so apologies in
advance if this is not the correct forum.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I am working with QUADRATIC cells (2D/3D)
in unstructured grids and require a view of all the cell edges. I hit a
couple of snags along the way.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>1. <STRONG>vtkQuadraticQuad</STRONG>.cxx (revision
1.15) - about line 70 in GetEdge() : typo - the modulus should be 4 (the number
of edges).</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>2. <STRONG>vtkExtractEdges</STRONG>.cxx (revision
1.44) - about line 123 in Execute() : loop over the number of points along an
edge assumes a point order in increasing distance along the edge (first,
next, ... last) whereas GetEdge() returns (first, last, next...). Swapping the
last and mid-side nodes in the edge list gives me the required view of all the
cell edges.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Unfortunately, my build of the Windows debug dll's
leak memory. I am using W2K Professional MSVC6 s/p2ish. Is this likely to be a
problem with the s/p level ?</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>What I would like is to display the quadratic cell
edges as parabolas and not 2 linear segments. Can anybody point me in the right
direction?</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Many thanks.</FONT></DIV></BODY></HTML>
