glkit - Comparing GLKMatrix4 -


how compare 2 glkmatrix4, or @ least check if on identity matrix?

a cursory search of glkmatrix4.h shows no util function, , feeling silly checking every field manually this:

static bool glkmatrix4equaltomatrix4(glkmatrix4 a, glkmatrix4 b) {   return   a.m00 == b.m00 &&   a.m01 == b.m01 &&   a.m02 == b.m02 &&   a.m03 == b.m03 &&   a.m10 == b.m10 &&   a.m11 == b.m11 &&   a.m12 == b.m12 &&   a.m13 == b.m13 &&   a.m20 == b.m20 &&   a.m21 == b.m21 &&   a.m22 == b.m22 &&   a.m23 == b.m23 &&   a.m30 == b.m30 &&   a.m31 == b.m31 &&   a.m32 == b.m32 &&   a.m33 == b.m33; }

you can transform string , compare using function nsstringfromglkmatrix4
