Abstract:
1. A method for displaying a three-dimensional polygon on a screen, comprising: a three-dimensional environment initializing step of initializing three-dimensional display environments; a view point setting step of setting a view point and a sight line based on coordinates of a reference position after the three-dimensional environment initializing step; a projection parameter setting step of setting projection parameters after the view point setting step; a three-dimensional model input step of receiving three-dimensional models with three-dimensional coordinates for an area based on the coordinates of the reference position; a polygon reconstituting step of classifying the three-dimensional models input in the three-dimensional model input step according to the positions of nodes of polygons for the three-dimensional models, and converting coordinates of the nodes using values set in the three-dimensional environment initializing step, the view point setting step and the projection parameter setting step into coordinates to reconstitute polygons for the classified models; and a screen displaying step of displaying the polygons reconstituted in the polygon reconstituting step on the screen.
