Description

Straight forward implementation of the paper "Meshless Deformation Based on Shape Matching"

http://dl.acm.org/citation.cfm?id=1073216

Building and Usage

####Dependencies

This code has the following dependencies (other versions may work):

• dlib 18.5
• GLM 0.9.5
• GLFW 2.7
• GLEW Supporting OpenGL 3.3
• OpenGL 3.3

####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.

Visuals

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
