Procedural deformation and destruction in real-time
2010-02-16 by Christofer Stegmayr
Special effects are almost exclusively done on computers today. Explosions, fires and destruction are most popular in action movies. These effects usually take several days or months to simulate on a computer in order to get the desired result. A field that is fairly new, in special effects, is solid mechanics. In other words, how materials deform and fracture. This is also a wanted effect in computer games.
The aim of this thesis is to simulate solid mechanics in real-time > 15 Hz. Several methods is evaluated and a primary method is implemented. The primary method implemented is the Element Free Galerkin EFG method. This is a meshless method which uses moving least square MLS approximations to calculate gradient of the deformation, which is used to approximate the strain of the material. The simulations, in this thesis, is parallelised and threaded in order to get better performance.
