To run the application, "make && ./main" should be enough, if glut is installed. When up and running, you can choose view:
0: original model 1: voxel model (cubes) 2: reconstructed model (marching cubes) 3: original model angle histogram 4: reconstructed model angle histogram 5: voxel model (spheres) 6: free fall/collision simulation
by pressing the corresponding number, and navigate with mouse (left click drag and scroll). Right click gives menu options for wireframe or solid rendering. Press 't' to toggle texture (on some views).
Increase or decrease voxel resolution with 'i' and 'd', respectively.
Press buttons 'f' or 'c' to build a free fall or collision simulation for the current voxel model, and switch to view '6' to watch it. Adjust frame step with ',' and '.' to rewind or fast forward the simulation.
