Authors: Sadashige Ishida and Masafumi Yamamoto
Lisence: MPL-2.0

Basic Usage

Running the executables without command line arguments will display the usage. Data files are located in the hgf_assets folder.

[KEY SETTING]
Space: Turn on/off the clock.
s: Proceed one time step.

Slash: Turn on/off the scene specific update.
b: Burst a randomly chosen bubble.
l: Move constrained vertices to left.
r: Move constrained vertices to right.
+: Inflate a bubble.
-: Deflate a bubble.

m: Change rendering mode.
o: Save the state as files containing information of mesh, labels, and constrained vertices.
O: Save the state as above, but with ghost vertices and faces.
