hi dear Gmsh creators
I'm a mechanical engineering student and I'm trying to add the ability to draw
nurbs curves to your great product Gmsh.
My question may seem kinda silly but which function(s) is (are) resposnible for
drawing B-splines in the source code?
As far as I discovered when clicked on an elementry entitiy like "B-spline"
the function "geometry_elementary_add_new_cb()" calls
add_new_multiline() and sends "Bspline" to this function. Then this function
waits until the control points are chosen and afterward sends the type of the
curve,the
points and the file name to a function called "add_multline()" and this
function saves the type of the curve and the control points in a string and
sends this string
and the filename to the function add_infile().
Am I totally right so far?
If yes,I dont really know what happens after that. :-?
How does the program then use this data?and how does it then draw the
B-spline?(using which functions?)
I found a fucntion called "addnurbs()" in the source code?is this function
responsible for that?I dont guess so,Beacause I didn't find where the inputs of
this
function come from.
Any help would be gratefully appreciated
Pouriya :)
