Paolo Cignoni 7befff7bec make point2 derived Eigen's Matrix, and a set of minimal fixes to make meshlab compile 
with both old and new version. The fixes include:
- dot product: vec0 * vec1 => vec0.dot(vec1) (I added .dot() to the old Point classes too)
- Transpose: Transpose is an Eigen type, so we cannot keep it if Eigen is used. Therefore
  I added a .tranpose() to old matrix classes, and modified most of the Transpose() to transpose()
  both in vcg and meshlab. In fact, transpose() are free with Eigen, it simply returns a transpose
  expression without copies. On the other be carefull:  m = m.transpose() won't work as expected,
  here me must evaluate to a temporary: m = m.transpose().eval(); However, this operation in very
  rarely needed: you transpose at the same sime you set m, or you use m.transpose() directly.
- the last issue is Normalize which both modifies *this and return a ref to it. This behavior
  don't make sense anymore when using expression template, e.g., in (a+b).Normalize(), the type
  of a+b if not a Point (or whatever Vector types), it an expression of the addition of 2 points,
  so we cannot modify the value of *this, since there is no value. Therefore I've already changed
  all those .Normalize() of expressions to the Eigen's version .normalized().
- Finally I've changed the Zero to SetZero in the old Point classes too.

Paolo Cignoni 4db69febbe big replacement .Zero => .SetZero, and start of Eigen's compatibilities (currently disabled by default) 2008-10-27 14:48:14 +00:00
Paolo Cignoni 5082a0cb03 Corrected a very small bug in the finalize of the quadric simplification, (RW flags were not correctly restored at the end of the simplification) 2008-07-17 06:52:56 +00:00
Paolo Cignoni 437d258a22 Added (from an idea of Fabio Ganovelli) the possibility of adding face-quality driving quadrics. For each face, three quadric perpendicular to the face plane and passing through the edges are added (just like for borders, but with a much lower weight). In case of very planar surface these quadrics try to keep the original shapes of triangles, preferring small edge collapse. Without this in planar zones collapse order could be random. 2008-07-15 07:15:18 +00:00
