Abstract
In an information processing apparatus for conducting an affine transformation representative of a matrix obtained by multiplying a matrix A for the affine transformation by λ(≠0) is stored in a memory section in advance. In case of conducting calculation processing for transforming coordinates (x,y,z)t into coordinates (x′,y′,z′)t by means of the affine transformation, A′ and a matrix (t1,t2,t3)t are read from the memory section,x′=(a′11*x+a′12*y+a′13*z)/λ+t1;y′=(a′21*x+a′22*y+a′23*z)/λ+t2;z′=(a′31*x+a′32*y+a′33*z)/λ+t3;are calculated, and the coordinates (x′,y′,z′)t are obtained.
