Server side installation

Using a Linux system for the server could simplify some installation steps.

1. Install libigl here.

In: server/matryoshka/cmake/FindLIBIGL.cmake

set(Matlab_ROOT_DIR "/path/to/matlab")

5. Adjust the contFilePath variable in matryoshkaModular.cpp with the path to scrapLibrary/contFiles/.

In: server/matryoshka/matryoshkaModular.cpp, line 236

contFilePath = "/path/to/scrappyLibrary/contFiles/" [...]

6. Build the matryoshka project.

cd server/matryoshka
mkdir Release
cd Release
cmake -DCMAKE_BUILD_TYPE=Release ..
make -j8

7. Install venv.
8. Start the django server.

cd server/server
source bin/activate
cd django/scrappy
python manage.py runserver 0.0.0.0:47555

9. Adjust IP and run a server for a client IP.

In: server/server/server.py, lines 15 and 19
Adjust IP address to match clients

cd server/server
source bin/activate
python server.py

4. Adjust IP to match server IP in ScrappyAdd-In.py.

In: client/Fusion360/ScrappyAdd-In/ScrappyAdd-In.py, line 56
Adjust IP to matcher server IP

5. In Fusion360, run the add-in.
6. Show the scrapLibrary panel from the Tools panel to start using Scrappy.
7. Install node.js.
8. Start the kiri:moto slicer .

cd client/grid-apps/
npm i
npm start
