<p>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.</p> |
