“…Enlarging the soft cfm value, from the original 0.3 to 1, indicates that there will be very obvious object penetration phenomenon; the testing result is shown in Figure 6; there appears very obvious penetration phenomenon between the wheel and the ground [18].…”

“…After the vehicle model rolls over, continue to give power to the vehicle, and the vehicle has no side slide but has been static. (FDS indicates the lateral slide phenomenon due to the lateral external force when the object is moving, and the sliding distance is proportional to the moving speed of the object and the external force, so FDS is also called lateral force slide coefficient [18,19]. )…”

Computer 3D character animation essentially is a product, which is combined with computer graphics and robotics, physics, mathematics, and the arts. It is based on computer hardware and graphics algorithms and related sciences rapidly developed new technologies. At present, the mainstream character animation technology is based on the artificial production of key technologies and capture frames based on the motion capture device technology. 3D character animation is widely used not only in the production of film, animation, and other commercial areas but also in virtual reality, computer-aided education, flight simulation, engineering simulation, military simulation, and other fields. In this paper, we try to study physics based character animation to solve these problems such as poor real-time interaction that appears in the character, low utilization rate, and complex production. The paper deeply studied the kinematics, dynamics technology, and production technology based on the motion data. At the same time, it analyzed ODE, PhysX, Bullet, and other variety of mainstream physics engines and studied OBB hierarchy bounding box tree, AABB hierarchical tree, and other collision detection algorithms. Finally, character animation based on ODE is implemented, which is simulation of the motion and collision process of a tricycle.

“…We have observed in the last decade a renewed interest in the use of physical simulation for interactive character animation and simulation, and many recent publications demonstrate tremendous improvements in robustness, visual quality and usability. For a detailed review about physics-based character animation, we refer the reader to the survey paper [61]. In a physics-based system, virtual humans need forces and torques to actively move around.…”

“…A recent survey can be found in [Geijtenbeek and Pronost 2012]. The controllers are often structured around a sequence of motion phases, represented as states in a finite state machines, with further continuous feedback laws added within each state, such as those that make use of foot placement for balance [Raibert and Hodgins 1991;Hodgins et al 1995;Laszlo et al 1996;Yin et al 2007;Tsai et al 2010].…”

Figure 1: Pareto-Optimal controllers with respect to jump height and control effort. The first two images on the left represent natural motions while the two images on the right represent super-natural motions. AbstractOptimization is a natural tool for designing natural motion control strategies. However, optimal motions can be expensive to compute. Furthermore, we are often interested in knowing an entire family of optimal motions rather than single motion. For a motion such as a jump, the solution family of interest is described by the pareto-optimal front that defines the trade-off between effort and jump height. In this paper we explore algorithms for computing a set of controllers that span the pareto-optimal front for jumping motions. Once computed, these controllers can then drive physicsbased simulations in real time. We also develop supernatural jump controllers through the optimized introduction of external forces. We show that the pareto-optimal front can naturally span both natural and supernatural regimes. This allows for controllers that can naturally transition from physics-based motions to motions assisted by external forces as the task demands increase.
