摘要： The present invention provides methods for determining a collision between a first deformable object and a second deformable object in a virtual reality simulation, the method including the steps of providing a first test capable of determining the proximity of the first object to the second object, providing a second test capable of determining the proximity of the first object to the second object, wherein the second test is more comprehensive than the first test, and wherein the second test is capable of being implemented once the first test returns a positive result. Since the more comprehensive test is implemented only when a collision is likely or imminent (as determined by the first test), the processor executing the simulation is not unduly burdened, and can devote resources to other tasks required by the simulation program.

摘要： The invention relates to a method for the interactive simulation of contact between objects. The inventive method comprises the following steps, namely: the parameters describing the physical characteristics of each of the objects are calculated; at the beginning of each simulated model sampling time period, each object is subjected to a real-time analysis of the specific behaviour thereof according to a free movement that does not take account of possible subsequent contacts, and, subsequently, at a global scene level, pairs of detected intersecting objects are subjected to a real-time analysis; a list of collision groups is established; for each collision group, parameters representing the physical characteristics of the objects and the description of the collisions are returned in real time, such as to characterise the contact between two objects in the case of a pure relative sliding movement; and, for each object, the specific behaviour of the object following the collision is displayed in real time and the set of real-time processes is performed with a shorter calculation time than the sampling time.

摘要： A method for animating soft body characters (Fig. 9) has a preparation phase (305) followed by an animation phase (310). In the preparation phase, the skin deformation of the character model is determined for a set of basis poses. The skin deformation from posing is compactly represented in terms of the set of basis poses. In the animation phase, the set of basis poses and the skin mode response are used to create a final posed character. A desired character pose is projected onto the basis set to determine a set of basis weights. The basis weights are applied to the set of skin responses to create a skin pose response, and the skin pose responses is projected onto the basis set to create the posed character model.

摘要： A method of collision detection is provided that allows for virtual objects having arbitrary shapes to be simulated with six degrees of freedom. The collision detection method is capable of providing full body contact by detecting each intersection between a representation of a first virtual object and a representation of a second virtual object. The full-body contact may be provided as haptic rendering signals indicating the full-body contact between the two virtual objects.

摘要： The invention provides a virtual assembly design environment (VAE) that can simulate axial and planar constrained motion for multiple parts in any combination and application order. Each sequence of assembly operations can be recorded and stored for later usage. A guidance mechanism may be employed by a user to assist in performing the assembly operations. Dynamic simulation methods may be used to simulate object behavior in the VAE using physical laws and collision detection algorithms. The physical properties of the parts can be created in a separate CAD system (including mass properties). In the invention, physical property information is transferred from the CAD system to a virtual reality environment where it is used in dynamic simulations. The parts behave realistically in the user's hand, constrained on the base part, or moving freely in space. A swept volume can be generated directly in the CAD system which is more accurate and compact than those created using numerical methods and can be easily processed by CAD systems. A swept volume trajectory editing mechanism has been implemented. Real time bi-directional data transfer between the VR environment and the CAD system has been achieved. The user can perform parametric design modifications in the virtual environment through a CAD system.
