| Research Abstract |
Computer graphic simulation of changes in the scene at stone-quarrying sites was performed for landscape evaluation of mined-out quarry. Results obtained are as follows :
1.Various kinds of data concerning crused stone were gathered.
2.A wireframe model and a polygon model were examined to predict changes in the geographical features of quarries on the basis of existing stone-quarrying plants.
3.It was disclosed that techniques of montage and perspective projections were useful to depict the color and the other features of the surface of mountains, the course of tree planting on the pit face and the features of a newly developed pit face. By combining these techniques, we devised a method for editing two-dimensional still pictures from various angles. Still images of the current scene and the predicted future scene were made while gradually changing the angle of view.
4.Cluster analysis was also performed using the evaluation results of semantic differential method, which clarified that the factor of landscape evaluation of mined-out quarry changed in distance. Size scale and beauty scale were important when it was seen at a short distance, whereas impression impact was important when it was seen at a long distance.
These simulation method found to be quite useful in obtaining basic data concerning future changes in the scene which could be cause by stone quarrying.
