Abstract
When a car turns, a visual point position CP and a sight line direction T are moved (from CP′ to CP and from T′ to T) in accordance with a turning angle of the car, and a displacement u of the visual point position (CP″) is made different from a displacement v of the sight line direction (T″). A ratio of the visual point position displacement u to the sight line direction displacement v is about 1:5.
Claims40
A picture processing apparatus comprising:
- a shape memory with shape data of an object previously stored therein;
- a processor for setting a coordinate value of an object in a three-dimensional virtual space on the basis of the shape data stored in said shape memory;
- transformation means for receiving the coordinate value set by said processor and transforming the coordinate value into a visual field coordinate system based on a specified visual point;
- and
- visual point setting means for moving the visual point position from a predetermined standard position for a predetermined base object as defined in the three-dimensional virtual space on the basis of data of the base object as well as changes in the situation caused by the movement of the base object, and for sending a new position after the movement to said transformation means.
A picture generating apparatus for generating a picture at an attention point as seen from a visual point, the visual point being set at a specified elevated position behind a moving object moving in a virtual space, and the attention point being set at a specified position in a moving direction of the moving object,
- wherein said picture generating apparatus comprises visual point position setting means for moving the visual point position after, with some delay, any change in a posture of the moving object when such a change occurs, and for causing the visual point to approach the specified position of the moving object.
A picture generating apparatus for generating a picture of a virtual space as seen from a visual point, the visual point being set at a specified elevated position behind a moving object moving in the virtual space,
- wherein said picture generating apparatus comprises:
- moving direction accepting means for accepting a moving direction designation for the moving object from an operator;
- and
- visual point position setting means for moving the visual point position in a direction opposite to the moving direction designation.
A picture processing method comprising:
- a coordinate setting step of setting a coordinate value of an object in a three-dimensional virtual space on the basis of shape data stored in a shape memory;
- a transformation step of receiving the coordinate value set by said coordinate setting step and transforming the coordinate value into a visual field coordinate system based on a specified visual point;
- and
- a visual point setting step of moving the visual point position from a predetermined standard position on the basis of data of a predetermined base object as defined in the three-dimensional virtual space as well as changes in the situation caused by the movement of the base object, and setting a new position after the movement as the specified visual point in said transformation step.
A medium with a program stored therein for causing a computer to perform a coordinate setting procedure, a transformation procedure and a visual point setting procedure,
- said coordinate setting procedure for setting a coordinate value of an object in a three-dimensional virtual space on the basis of shape data stored in a shape memory,
- said transformation procedure for receiving the coordinate value set by said coordinate setting procedure and for transforming the coordinate value into a visual field coordinate system based on a specified visual point, and
- said visual point setting procedure for moving the visual point position from a predetermined standard position on the basis of data of a predetermined base object as defined in the three-dimensional virtual space as well as changes in the situation caused by the movement of the base object, and setting a new position after the movement as the specified visual point in said transformation step.
