Developed in the frame of the EUMETSAT Polar System Second Generation (EPS-SG) by CNES, the IASI-NG System is in charge of providing geo-localized, calibrated (spectrally and radiometrically) and apodized radiances to be used in the elaboration of geophysical products giving information on variables of the atmosphere, the ocean and land surfaces. It is composed of a space segment (IASI-NG instrume...Show More
The Geostationary Ocean Color Imager (GOCI) has been developed for the first time to provide multispectral data which is useful to detect, monitor, and predict short-term changes of coastal ocean environment around the Korean Peninsula from a geostationary platform. In this paper, an in-orbit solar calibration method for GOCI is introduced. Based on the radiometric model of GOCI, solar calibration...Show More
This research work is aimed toward the development of a VR-based trainer for colon cancer removal. It enables the surgeons to interactively view and manipulate the concerned virtual organs as during a real surgery. First, we present a method for animating the small intestine and the mesentery (the tissue that connects it to the main vessels) in real-time, thus enabling user interaction through vir...Show More
This paper presents a method for animating and rendering an interactive natural scenery in real-time. It improves the prairie model of [I I I] by enabling the on-the-fly generation of blades of grass, at three different levels of detail, from user-specified density maps. A new animation function, the tread on grass, is defined to allow virtual objects or characters to crush the grass. The resultin...Show More
A new dynamics algorithm for articulated solid animation is presented. It provides enhancements of computational efficiency and accuracy control with respect to previous solutions. Iterative refinement allows us to perform interactive animations which could be only computed off-line using previous methods. The efficiency results from managing two sets of constraints associated with the kinematic g...Show More
