IMAGE PROCESSOR, GAME MACHINE, ITS METHOD AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide an image processor which shows a transparent object with a rich feeling of a material and also in a fast way. SOLUTION: This device is provided with a vector operating means which generates; a sight line vector E that shows a line of sight from the viewpoint which sees through space to a transmitted object M, a normal line vector N in a 1st intersection P1 that is an intersection of the vector E and the surface of the object M; and a refractive vector R that shows a direction in which an optical axis corresponding to the vector E is made incident on the object M and deflects based on the vectors E and N. The device is further provided with a rendering means which specifies a 2nd intersection that is an intersection of a texture plane TP setting a specific texture and the vector R generated by the vector operating means and which determines texture that is near the position P1 of the object M based on texture data which is set to the specified intersection P2 . A transparent object is shown in real time.
