[Scilab-users] Surface calculation

[Rafael Guerra]

Hi Paul,

Season’s Greetings.

Could you provide one representative example of your input mesh files?

Regards,
Rafael

Hi

The topic remains open (one never knows), but I think I found an interesting way to answer to my needs: the "ear clipping method"; then based on the triangles it becomes easy to calculate the surface.

Hi All

I'm wondering how I can calculate (with accuracy) the value of any
closed surface composed of edges; these ones come from a mesh and the
surface is no more than a hole.

In a first step I'm thinking in  Delaunay triangulation based on the
edges to mesh the surface (triangles), but maybe there are simpliest
ways (to avoid to reivent the wheel)? does somebody can advice?

Obviously the surface can be highly irregular, such as a daisy flower
(to illustrate the shape).

Merry Christmas to all the community

Paul
