Abstract
A drawing apparatus is for drawing a three-dimensional model including a plurality of nodes present in a three-dimensional space, by using a plurality of viewpoints. The drawing apparatus includes a memory configured to store drawing information including a correspondence relationship between the plurality of nodes and the plurality of viewpoints, and drawing parameters relevant to the plurality of viewpoints; and a CPU configured to transform the three-dimensional model into an image, by a plurality of polygons constituting the three-dimensional model, by using the drawing information. The CPU changes the drawing information in response to a position or a state of a predetermined one or a plurality of the nodes satisfying a predetermined condition, and calculates drawing positions of vertices of the plurality of polygons, by using the viewpoints corresponding to the nodes to which the vertices belong, based on the changed drawing information.
