Illumination consistency is important for photorealistic rendering of mixed reality. However, it is usually difficult to acquire illumination conditions of natural environments. In this paper, we propose a novel method for evaluating the light condit

In designing the color of outdoor industrial products such as cars and bridges, the optical balance of its model and background photograph (or each frame of the video sequence) needs to be maintained. To irradiate incident light onto a model, obtaini

Water surface is one of the most important components of landscape scenes. When rendering spacious water surface such as that of the lakes and reservoirs, aliasing and/or moire artifacts frequently occur in the regions far from the viewpoint. This is

We propose a fast approach for photo-realistic rendering of trees under various kinds of daylight, which is particularlyuseful for the environmental assessment of landscapes. In our approach the 3D tree models are transformedto a quasi-3D tree databa

It is a difficult task to automatically extract contour lines from a raster image topographic map and give each contour line its inherent elevation. In this paper, the authors propose an automatic contour line extraction algorithm based on the contin
