CGAL is a collaborative effort of several sites in Europe and Israel. The goal
is to make the most important of the solutions and methods developed in
computational geometry available to users in industry and academia in a C++
library. The goal is to provide easy access to useful, reliable geometric
algorithms.
The CGAL library contains:
* the Kernel with geometric primitives such as points, vectors, lines,
predicates for testing things such as relative positions of points, and
operations such as intersections and distance calculation.
* the Basic Library which is a collection of standard data structures and
geometric algorithms, such as convex hull in 2D/3D, (Delaunay)
triangulation in 2D/3D, planar map, polyhedron, smallest enclosing
circle, and multidimensional query structures.
* the Support Library which offers interfaces to other packages, e.g., for
visualisation, and I/O, and other support facilities.

vtk43 just committed requires outdated expat.5. This will
cause the build to fail if expat.6 is installed. I've been
running caret (an application that depends on vtk43) with
expat.6 for several weeks without any apparent problems.
Suggest updating the vtk43 LIB_DEPENDS to allow expat.5 or
expat.6.

I'd like to reintroduce VTK 4.3 to the ports tree to
facilitate building a new port, Caret 5.3. Starting with
VTK 4.4, support for "float" coordinates has been dropped
from many functions. The Caret code will require significant
changes to compile with VTK 4.4. Since the Caret developers
do not yet have a timeline for upgrading to VTK 4.4, I'd
like to reintroduce VTK 4.3 for the interim. Only the vtk
base and vtk-headers are essential. Below are shar files
for these two trees. They are based on the original vtk
4.3 port. The only modifications are:
1. The folder names are changed from vtk and vtk-headers
to vtk43 and vtk43-headers to prevent a collision with the
current vtk in /usr/ports/math.
2. PREFIX is set to ${LOCALBASE}/vtk43 to prevent a collision
with the current vtk installation.
