摘要
PURPOSE: A graphic data processing method and a linear expression transforming method for efficiently implementing a linear expression on a graphic processor are provided to efficiently implement an application using the linear expression of an affine transformation form on a vertex shader offered from the graphic processor. CONSTITUTION: An object expense is fixed(S12). The transformed linear expression of the linear expression is found out. The expense needed for calculating the linear expression and the transformed linear expression is calculated(S15). A difference between the expense needed for calculating the linear expression and the transformed linear expression is calculated(S16). If the difference is smaller than zero or a probability to get to zero in a progress process is large, the transformed linear expression is fixed as a new linear expression. Until the expense needed for calculating the linear expression gets to the object expense, the previous processes are repeated.
