Abstract:
1. A program for projecting a predetermined image onto a character of a game in a game wherein the character is characterized by a plurality of polygon planes, machine having an operation unit for executing predetermined operation in a screen, a calculation processing unit for executing predetermined calculation, and a control unit connected with the operation unit and the calculation processing unit and for controlling the calculation processing unit, the program encoded in computer readable medium and configured to be executed by the game machine, the program comprising: an image creation process which creates an image consisting of two-dimensional coordinates with the control unit by operating the operation unit; and a pasting process which arranges the image created by the image creation process and a virtual light source for projecting the image onto the character at an arbitrary position in the vicinity of the character in a three-dimensional virtual space, based on an input signal from the operation unit, and for pasting on the character a projected image created by projecting the image onto the character from the projected virtual light source, wherein the pasting process pastes on the character the projected image such that the projected image projected on only a polygon plane of the plurality of polygon planes closest to the virtual light source remains after the character is pasted on all of the plurality of polygon planes from the virtual light source by a projecting process using a light matrix, a view matrix, and a projection matrix; and the pasting process creates the view matrix using the light matrix and the projection matrix.
