Abstract:
A three-dimensional simulator apparatus for synthesizing a field-of-view image as seen from an observer within a virtual three-dimensional (3D) space configured of a plurality of display objects, comprising:movement information computation means for computing at least one of a velocity and a rotational velocity of at least one of said display objects based on at least one of an operating signal input by said observer through control means and an instruction from a computer; texture computation means for performing computations to map textures onto said display objects; texture information storage means for storing information of said textures to be mapped by said texture computation means, said texture information storage means for storing different types of texture information corresponding to the same display object; and changing means for changing one of a type of information of at least one texture to be mapped onto at least one of said display objects and information specifying said type in accordance with at least one of said velocity and said rotational velocity of said at least one of said display objects; wherein said at least one of said display objects moves or rotates with said texture being mapped onto said moving or rotating display object, and one of the type of information of texture and information specifying said type is changed in accordance with at least one of said velocity and rotational velocity of said moving or rotating display object, and wherein texture information for a stopped state is used when said display object stops, and same texture information is used when said display object moves or rotates at a low speed, and one of the type of information of texture and information specifying said type is changed when the display object moves or rotates at an intermediate speed.
