Multi-view drawing apparatus of three-dimensional objects, and method

A drawing method of drawing a three-dimensional model including a plurality of nodes present in a three-dimensional space, by using different perspective projections based on a plurality of camera viewpoints,

• the drawing method being executed by a CPU by using drawing information stored in a memory, the drawing information including a correspondence relationship between the plurality of nodes and the plurality of camera viewpoints, and drawing parameters relevant to the plurality of camera viewpoints, the drawing method comprising:
• changing 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
• calculating drawing positions of vertices of a plurality of polygons constituting the three-dimensional model, by using the camera viewpoints corresponding to the nodes to which the vertices belong, based on the drawing information including changed drawing information, wherein
• in at least one combination of a first camera viewpoint from among the plurality of camera viewpoints, a second camera viewpoint from among the plurality of camera viewpoints, and a node from among the plurality of nodes,
• a position of the node in a first image, in which the node is drawn using the first camera viewpoint and a drawing parameter corresponding to the first camera viewpoint, is the same as the position of the node in a second image, in which the node is drawn using the second camera viewpoint and a drawing parameter corresponding to the second camera viewpoint.

• acquiring a correspondence of regions from a plurality of regions of a standard model for which drawing information is defined and a plurality of regions of the three-dimensional model for which drawing information is not defined;
• applying the drawing information of the standard model to the three-dimensional model based on the correspondence of regions;
• storing the applied drawing information in the memory;
• and
• calculating drawing positions of vertices of a plurality of polygons constituting the three-dimensional model, by using the camera viewpoints corresponding to the nodes to which the vertices belong, based on the drawing information stored in the memory, wherein
• in at least one combination of a first camera viewpoint from among the plurality of camera viewpoints, a second camera viewpoint from among the plurality of camera viewpoints, and a node from among the plurality of nodes,
• a position of the node in a first image, in which the node is drawn using the first camera viewpoint and a drawing parameter corresponding to the first camera viewpoint, is the same as the position of the node in a second image, in which the node is drawn using the second camera viewpoint and a drawing parameter corresponding to the second camera viewpoint.
