This project combines my Felt deformable surface library with the excellent open source Urho3D game engine.
A demo video is available at https://www.youtube.com/watch?v=KwpXzBb6Nzs
The MRI brain scan asset was obtained from BrainWeb.
The business logic is written in Lua via moonscript. The key addition to the Felt library are the additional Bullet collision shape classes, allowing for interaction with the physics engine.
The default demo is of a surface in the shape of a brain, which can be deformed with mouse clicks and have boxes thrown at it.
Press SPACE to enter/leave mouse capture mode, allowing the viewport to rotate as the mouse is moved.
Use W, S, A, D, X, and Z keys to move around.
In mouse capture mode, left-click to throw a box.
In normal mouse mode, left-click on the surface to destroy and right-click to raise the surface.
Moonscript/Lua scripts are found in bin/Data/Scripts. Edit the main.moon (or main.lua, to
avoid transpiling) file to show different demos.
Currently the only other demo is segment, which constructs the surface segmentation of grey
matter from an MRI image, and does not include any physics.
