Abstract: Provided is a golf game that is readily intuitively playable by a user. An input reception section receives an operation input indicating a motion of an input device gripped by the hands of the user. A control section controls a motion of a player character in a game space in accordance with the operation input. An image generation section generates a game image. When a golf club held by the player character comes into contact with the ground in the game space, the control section drives a stimulus generation section disposed in the input device to stimulate the user's hands gripping the input device.

Abstract: An image drawing technique includes a method of drawing a randomly changing image of an object and a method of drawing a revised image including a shimmering image in a background image. The method of drawing a randomly changing image of an object establishes a drawing pattern of the object, the drawing pattern including a plurality of extraction areas, each extraction area including a portion of the drawing pattern. A portion of the drawing pattern is extracted from one of the extraction areas and is combined with a randomly selected mask pattern to draw a composite image which is output on a monitor. The extracting and combining steps are repeated for a next extraction area located at a predetermined distance in a defined direction from a previous extraction area. The method of drawing a revised image includes randomly altering a portion of the background image to generate an altered image, and combining the altered image and another mask pattern to generate another composite image.

Abstract: A first texture is used for determining color and design of a polygon structuring an object rendered upon a two-dimensional screen. A second texture has a pattern of dense distribution of color with a predetermined slant relative to the two-dimensional screen. An rendering processing device first applies a first texture to a polygon structuring an object, and thereafter performs translucent synthesis of a second texture on an object applied with the first texture, thereby making it possible to easily render an image in a hand-drawn illustration style in, for example, home video games and computer graphics.

Abstract: A primary polygon is processed to generate new secondary polygons utilizing a light source as a base point. A front-side secondary polygon is selected from the secondary polygons and drawn in a blackish color by rendering and hidden surface removal utilizing Z-buffering. Then, back-side secondary polygons are drawn by rendering and hidden surface removal utilizing Z-buffering such that the blackish color in portions of the front-side secondary polygon is eliminated, making these portions transparent.

Abstract: An entertainment system has a normal action rendering means for displaying a normal action image in which at least two hypothetical characters are making a normal action, and a special action rendering means for displaying a special action image in which at least one of the hypothetical characters changes from a normal action to a special action when a predetermined condition is satisfied, and the special action made by the one of the hypothetical characters is completed when a control action made by the user satisfies a predetermined control condition indicated in a guidance, and a image display means for outputting image data stored in an image memory to a display monitor to enable the display monitor to display an image based on the image data.
