Mesh Boolean problem #75

Closed Boccio90 closed 4 years ago

Boccio90 commented 6 years ago

i've 2 stl files, and i'm tryngo to do simple boolean operation in matlab, i'm loading the two meshes with mesh_load and then i get this error while doing mesh_boolean, some suggestion?

Error using intersect (line 80) Not enough input arguments.

Error in importare (line 16) [V2,F2]= mesh_boolean(V,F,V1,F1, intersect);

alecjacobson commented 6 years ago

intersect should be "intersect"

Boccio90 commented 6 years ago

my bad, but i've already tried 'intersect' and still got errors.

Attempt to execute SCRIPT mesh_boolean as a function:

it's probably a problem of path?

alecjacobson commented 6 years ago

what do you see if you issue

 which mesh_boolean
Boccio90 commented 6 years ago

only this file.

C:\Users\Utente\Desktop\Matlab\Importare STL\alecjacobson-gptoolbox-8c1bad1\mex\mesh_boolean.m

i'm pretty new in matlab and i could have done some newbie error...

alecjacobson commented 6 years ago

Everything in the mex/ folder needs to be compiled. The .m files there only exist so help can be generated. See the mex/README.md for instructions

cmake .. Undefined function or variable 'cmake'.

Probably i'm too new to matlab to do such things ;) sorry for wasting your time i've not installed cmake correctly i guess...

alecjacobson commented 6 years ago

cmake needs to be issued on the terminal (not in Matlab).

You might need to install cmake first.

(.mex files are actually C++ programs that are compiled in a way that matlab can call them as functions. So it might take some getting familiar with before attempting to compile this.).

Boccio90 commented 6 years ago

i've made a little step forward with cmake, but now when i compile i got this error:

CMake Error at cmake/FindELTOPO.cmake:22 (message): could NOT find LIBELTOPO_INCLUDE_DIR Call Stack (most recent call first): CMakeLists.txt:11 (find_package)

any clue?

alecjacobson commented 5 years ago

The new CMakeLists.txt might handle your issue better. If you happen to try again, let me know if it works.
