Re: Mesh Generation using Media Axis

Hi!

Is your object in 2D or 3D? What "mesh" do you have in mind?
If the object is in 2D, do you want a triangle mesh that approximates
the object itself? If the object is in 3D, do you want a tetrahedron
mesh to approximate the object or a triangle mesh to approximate
the boundary of the object?

A triangle or hexile mesh, usable for finite element anaysis. I already found a good example:

"A common example is the reuse of CAD designed solids in CAE (Computer Aided Engineering) simulations. In order to conduct such simulations (e.g., by using Finite-Elements-Analysis) the solid has to be represented as a mesh, which is in contrast to the way CAD applications store their objects. Several approaches exists, to convert solid models into meshes. A popular method is to use the geometric information provided by the medial axis of an object in order to cut the object. In general it is simpler to mesh smaller objects instead of complex ones. Another advantage is, that the medial axis can be used to identify and remove, for the FE analysis non relevant, features prior to the meshing process."
