Hi Yegor,
It sounds like an interesting project. We have been working with the
SolidWorks API programming interface to make various utilities. I think it
is possible to create the definition that you have described. Other
possibilities are to export the model to an SLA (StereoLithography) model or
to a faceted representation (collection of triangular surfaces with outward
normals). In either case we can determine if any coordinate is either inside
or outside of the volume.

Of course there are an infinite number of points inside the volume. I am
guessing that the MatLab program will use some array of points at a
specified spacing. I do not know if the points need to be mapped to some
shape however.

Please email me directly at Ranny@RespMech.com if you want to discuss it
further.

Thanks,
Ranny

YDS,
In SW cut through the solid in incremental planar cuts, export each iteration as an
ASCII STL file. Using PEARL or AWK and  SORT, reformat and take out normals and
remove redundant points.
Have fun,
Sam
