Abstract
An image processing method is disclosed for more effectively displaying movements of an object composed of a plurality of polygons. The image processing method displays a moving object by displacing backward given vertices of polygons composing the moving object, imparting an afterimage representation that makes the object look as if it leaves a trail in the direction opposite to their direction of movement. This allows for display of movements of the object in a more emphasized manner and display of the moving object with richer expression.

An image processing method for displaying an object, composed of a plurality of polygons, moving in a virtual three-dimensional space, the method comprising the steps of:
- acquiring, at every given sampling timing, coordinates of at least one vertex, whose normal vector has a component opposite to a movement direction vector of the object, among vertices of the polygons composing the object;
- and
- displaying the polygon having the at least one vertex assuming that coordinates of the at least one vertex are located at a position displaced by a given length in a direction having the component opposite to the movement direction.
An image processing apparatus for displaying an object, composed of a plurality of polygons, moving in a virtual three-dimensional space, the apparatus comprising:
- acquiring means which acquire, at every given sampling timing, coordinates of at least one vertex, whose normal vector has a component opposite to a movement direction vector of the object, among vertices of the polygons composing the object;
- and
- displaying means which display the polygon having the at least one vertex assuming that coordinates of the at least one vertex are located at a position displaced by a given length in a direction having the component opposite to the movement direction.
An image processing method for displaying an object such that the object moves on a screen, wherein
- the object is composed of a set of a plurality of pixels, the method comprising a step of moving pixels composing at least part of a region in the object by a given length in a direction having a component opposite to a movement direction of the object.
An image processing method for displaying a state in which an object, composed of a plurality of polygons, moving in a virtual three-dimensional space, moves in the virtual three-dimensional space, the method comprising the steps of:
- selecting at least one of vertices of the plurality of polygons composing the object;
- and
- displaying polygons having the selected vertices in a deformed manner assuming that the vertex coordinates are located at a position displaced by a given length in a direction having a component opposite to a movement direction of the object.
An image processing method for displaying a state in which an object, composed of a plurality of pixels moves in a virtual three-dimensional space, comprising the steps of:
- selecting at least one of the plurality of pixels composing the object;
- and
- displaying the selected pixels by moving the pixels to positions displaced by a given length in a direction having a component opposite to a movement direction of the object.
