Flexible Body Deformation

Simulation | Feb. 2018 (12 weeks) | OpenGL

For undergraduate lab work. I designed the deformation method for flexible body, and make a simple system demo. The project uses a Position-Based Dynamics method that I realized to connect with the physical model I got from the geometric mesh of the lung model. It can deal with two simple interaction: grab and cut.

Notable Contributions:

• Designing a soft body deformation method based on Position-Based Dynamics (PBD) using Shape Matching Constraint.

• Designing a particle generating method using a mesh grid from model file to represent the physics information of the soft body.

• Designing a coupling between the geometric model and the physical model.

• Designing a soft body cutting simulation method based on Unit Duplicating concept using Delaunay Triangulation.
