Real-time collision detection method for deformable bodies
نویسنده
چکیده
This paper presents a real-time solution for collision detection between objects based on the physics properties. Traditional approaches on collision detection often rely on the geometric relationships that computing the intersections between polygons. Such technique is very computationally expensive when applied for deformable objects. As an alternative, we approximate the 3D mesh in an spherical surface implicitly. This allows us to perform a coarse-level collision detection at extremely fast speed. Then a dynamic programming based procedure is applied to identify the collision in fine details. Our method demonstrates better prevention to collision tunnelling and works more efficiently than the state-of-the-arts.

TRANSACTIONS ON VISUALIZATION AND COMPUTER GRAPHICS 1 Real - time elastic deformationsof soft tissues for surgery
In this paper, we describe a new method for surgery simulation including a volumetric model built from medical images and an elastic modeling of the deformations. The physical model is based on elasticity theory which suitably links the shape of deformable bodies and the forces associated with the deformation. A real-time computation of the deformation is possible thanks to a pre-processing of ...
متن کاملReal-Time Cloth Simulation
The field of cloth-modeling has been widely investigated during the last decade. Many solutions have been proposed for the different aspects related to that field, ranging from fast cloth integration methods to complex collision handling. However, it is still challenging to perform simulations in real-time without compromise. In this thesis, we base our work on fast collision detection methods ...

متن کاملGPU-based Collision Detection for Deformable Parameterized Surfaces
Based on the potential of current programmable GPUs, recently several approaches were developed that use the GPU to calculate deformations of surfaces like the folding of cloth or to convert higher level geometry to renderable primitives like NURBS or subdivision surfaces. These algorithms are realized as a per-frame operation and take advantage of the parallel processing power of the GPU. Unfo...
