Abstract
A character object CH1 is first projected onto a screen plane, and a masked area is rendered as a circular area that is centered about the position of the character object CH1 projected onto the screen plane. The obtained image data is stored in a main memory as mask data, and is used when rendering each object in a virtual game space. A transparency flag is set in advance for each of field objects OB1 to OB3. The field object OB1 whose transparency flag is “1” is rendered by using the mask data, whereas the character object CH1 and the field objects OB2 and OB3 whose transparency flag is “0” are rendered normally. Thus, it is possible to provide a video game device capable of displaying a particular object such as the player character so that it can always be seen, with minimum detraction from the atmosphere of the game field.
