[Insight-developers] Missing faces using Quad Edge Mesh

[wlzhu]

Hi Dan,
          I think your input polygon cell should be consistent in
orientation direction, which is required to ensure each QuadEdge belongs to
one polygon cell.  I changed the point order of your input faces, it works.


  /*Face0*/ f[0]=0; f[1]=4; f[2]=7; f[3]=3; AddFace<TMesh>(cid, f, mesh);
  /*Face1*/ f[0]=0; f[1]=1; f[2]=5; f[3]=4; AddFace<TMesh>(cid, f, mesh);
  /*Face2*/ f[0]=1; f[1]=2; f[2]=6; f[3]=5; AddFace<TMesh>(cid, f, mesh);
  /*Face3*/ f[0]=3; f[1]=7; f[2]=6; f[3]=2; AddFace<TMesh>(cid, f, mesh);
  /*Face4*/ f[0]=0; f[1]=3; f[2]=2; f[3]=1; AddFace<TMesh>(cid, f, mesh);
  /*Face5*/ f[0]=4; f[1]=5; f[2]=6; f[3]=7; AddFace<TMesh>(cid, f, mesh);
