Straight forward implementation of the paper "Meshless Deformation Based on Shape Matching"
http://dl.acm.org/citation.cfm?id=1073216
####Dependencies
This code has the following dependencies (other versions may work):
####Building
To build run make which should produce an executable meshless.
To build with slow motion turned on run make slowmo.
####Usage
Run ./meshless [obj_file]. The OBJ file is optional and will run with the sphere.obj by default.
When the program is running h will print the controls to the console.
Performance is surprisingly good, running 100,000+ particles on an older system. Although, larger numbers of particles may require the SIM_DT to be changed in src/main.cpp.
Note about regular simulation: With high beta and low alpha values and large forces the mesh may turn inside out. To correct inversion throw the mesh again softer, this is a side effect of how the particle system is implemented.
Note about slow motion: The paper suggests a fix for variable time steps that can make the simulation more unstable, so try to avoid a combination of high beta and low alpha values.
Models created using Blender. I suggest loading more exciting models than these.
Slow motion enabled beta = 0.8, alpha = 0.2, cube. Example 1
Slow motion enabled beta = 0.8, alpha = 0.2, sphere. Example 2
Older video, before quadratic deformations were implemented. Example 3
