VISUAL POINT POSITION INPUTTING DEVICE

摘要

PURPOSE:To easily input a visual point position in an information processor forming a three-dimensional image by projecting an object existing in a three- dimensional model space into a two-dimensional plane. CONSTITUTION:It is supposed that a visual point exists in the original visual point position 31. An object 39 is projected to a screen plane 32 and an image 35 is formed. It is assumed that the visual point position is advanced up to a position where the image of the object 39 is displayed up to the whole vertical width of the screen plane 32. The visual point position is inputted as follows. A rectangle filling the vertical width with the image 35 is pointed out on the screen 32 by means of a rectangle upper left pointing marker 33 and a rectangle lower right pointing marker 34. Then the moving direction of the visual point is the advancing direction is specified by using a moving direction input device. After completing the above input, a new visual point position 36 for projecting the image 35 included in the rectangular area to the whole screen is found out.
