Possible bug in AffineTransform3D.transform(AffineTransform3D trans)

[Bernard]

Hi David,

I think I found bugs in transform(AffineTransform3D trans) :
-calculation is done in 2D although we are in 3D
(coefficients m2? and m?3 are not calculated) ;
-it does not fulfil "line by column" algorithm,
for instance :
double n00 = m00 * trans.m00 + m10 * trans.m01;
should be :
double n00 = m00 * trans.m00 + m01 * trans.m10 + m02 * trans.m20;

Same problems in preConcatenate(AffineTransform3D trans).

Regards,
Bernard

Hi Bernard,

thanks for reporting! I have fixed this, the new version is available from the subversion repository. I have also changed the method signature (returns a new transform instead of changing the local version).

regards,
David
