Abstract
The usefulness of computer graphics as a means of simulating changes in landscape caused by stone quarrying was examined. Montage and perspective projections were used to depict the color and 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. A wireframe model was used to predict changes in the geographical features of quarries on the basis of existing stone-quarrying plants. By combining these techniques, we devised a method for editing two-dimensional still pictures, obtained from video tapes, from various angles, i.e., by up to 30 degrees and the angle of elevation by up to about 10 degrees. Still images of the current scene and the predicted future scene were made while gradually changing the angle of view. These pictures were linked to each other to yield an animation which represents the expected changes in the scene as viewed from a car moving past the front of the quarry.
This simulation method allowed us to estimate changes in the scene in advance, and was found to be quite useful in obtaining basic data concerning future changes in the scene which could be caused by stone quarrying.
