Missing makefile
Hello Stefano,
It looks like you are one of the main fortran library dealer out there! :)
I am looking at this library to perform some is_inside operations on STL files in my code. I am trying to build FOSSIL and give it a go, but a makefile is missing and I am a bit stuck! I know you usually use fobis, but I am a very poor fortran person already using old style make file :p I can try to produce a makefile by myself, but before investing time in it, it is worth to ask you.
Many thanks!
Hello, I managed to compile fossil using a makefile. I can share it with you if you like. I have also built a make file for all the third party libs like VecFor that was missing as well.

Hi, sure, if you want to share your makefile it is really appreciated. I am working alone and I have not time to maintain other building systems than my own.
also stefano, since I know i will ask you later on, can you suggest me a way to check if a point is inside or outside an stl? is this library working also with non-convex regions? I thing so but worth to ask :)

FOSSIL provides some algorithms for computing the sign of distance, i.e. the sign means exactly if the checked-point is inside or not the surface. They should work also for non convex regions, but the surface must satisfy some requirements, e.g. being water tight.
@szaghi,
I am messing around with FOSSIL, but I am not sure i am doing it in the correct way! In particular, I am loading up an stl file (a cylinder) and then translating it in space. For some reasons, the result of statistics() is always the same, regardeless the fact I am translating the cylinder. Here is my pseudo-code:
STLFile%load_from_file(facet=this%regionSTL%STLSurface%facet, file_name=stlFileName, is_ascii=.true.) STLSurface%translate(x=delta(1), y=delta(2), z=delta(3)) STLSurface%analize() print '(A)', STLSurface%statistics()
Anything wrong with this?
EDIT: just find out that the metrix is not recomputed by default... it looks all good then.
EDIT2: originally my cylinder's center was [0,0,0] with a radius of 0.125. After translating it i see that the center does not update, is just an info does not udating? Any reason why I am getting a negative volume? Maybe normal orientation?
EDIT3: thanks for this lib, it works nicely for me :) that should have been an effort, much appreciated Stefano!
