Dependencies

Building

$ git clone https://github.com/Q-Minh/meshless-deformation-based-on-shape-matching
$ cd meshless-deformation-based-on-shape-matching
$ cmake -S . -B build -A x64 -DCMAKE_BUILD_TYPE=Release

# if using Visual Studio, you can open your .sln file now
$ cmake --build build --target App --config Release # or build in VS IDE

# run app in ./build/Release or ./build
$ ./build/Release/App.exe # or ./build/App on linux/macos

Usage

Generate force fields from your keyboard, pick object vertices to be fixed and pull on object vertices with mouse picking to play around with the model deformable objects. Customize the deformable object's behaviour by tweaking parameters in the imgui menu.

User Interaction

Fixed vertices

While holding down the shift key, press the left mouse button while hovering your mouse cursor on the object to make the pointed-to object's vertex fixed (if it was free) or free (if it was fixed) in space.

Picking

While holding down the ctrl key, press the left mouse button when your mouse cursor points on the object and hover your mouse cursor around in the direction you want to pull the pointed-to object's vertex in space.

Force Fields

Generate force fields in the up, down, left, right, forward and backward directions from your keyboard using, respectively, the i, k, j, l, space and b keys.
