This paper proposes an extended COLLADA-based File Format to support various attributes of realistic objects for Virtual Reality (VR) applications. VR applications provide the user with virtual objects represented as 3D CG. To provide realistic virtual objects in a VR application, the developer of the VR application has to define many attributes of the corresponding real objects besides their 3D geometry...
This paper proposes a surgical simulation system that supports a COLLADA file format, which is a XML based 3D model data format and also proposes its extended file format to represent various information useful for the surgical simulation, i.e., several parameters for a spring model of the skin or the internal organs used as a haptic device parameters and several text-based data used as annotations...
The authors have already proposed a cloth design system that provides intuitive operations, e.g., sewing, cutting and fitting a cloth in a virtual 3D space through direct manipulations using a force-feedback device, phantom. However, a phantom device is very expensive and it is difficult for the end user to buy and use it. Also, many users are familiar with the use of a mouse device rather than that...
