Paolo Cignoni 372ee1ed99 Corrected a small (!) bug in the IntersectionSegmentTriangle. (the line triangle intersection function returns a **signed** distance...) 2012-10-15 09:42:05 +00:00
Paolo Cignoni c059114300 Orthography lenght -> length 2012-10-08 09:05:11 +00:00

Paolo Cignoni db5320cc64 Modified IntersectionPlaneSegment so that it returns always the same intersection independently from the segment orientation 
Return false if segment is parallel with the plane.

Paolo Cignoni c1551eddfd make Point derive Eigen's Matrix and some cleanning 2008-10-28 11:47:37 +00:00
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 ab200fc950 Port to eigen2: state of the mess: 
* curently nothing change if you don't define VCG_USE_EIGEN
* make Matrix*, Point3 and Point4 derive Eigen::Matrix (still ugly)
* now catching all the dot products to replace them by .dot()
  note that most of meshlab already compile
