<p class=MsoNormal>I agree that this would likely be a good change. Could you
add a<br>
little more clarity to this? What class(es)/method(s) are you<br>
proposing to change?<br>

I think just vtkMatrix4x4::PrintSelf would need to be changed? Maybe something
more like this:<br>

It's tough to get the formatting VERY nice because of variable width character
fonts, but there is still quite an improvement (in my opinion). Here are two
examples:<br>
<br>
Existing method, hard matrix:<br>
1 -4.12726e-10 3.91703e-10 5.2556e-12 <br>
4.12726e-10 1 7.75407e-10 -7.62694e-10 <br>
-3.91703e-10 -7.75407e-10 1 7.57439e-10 <br>
0 0 0 1 <br>
<br>
Proposed method, hard matrix:<br>
1.000 -0.000 0.000 0.000<br>
0.000 1.000 0.000 -0.000<br>
-0.000 -0.000 1.000 0.000<br>
0.000 0.000 0.000 1.000<br>
<br>
<br>
Existing method, easy matrix:<br>
1 2 3 4 <br>
5 6 7 8 <br>
9 10 11 12 <br>
13 14 15 16 <br>
<br>
Proposed method, easy matrix:<br>
1.000 2.000 3.000 4.000<br>
5.000 6.000 7.000 8.000<br>
9.000 10.000 11.000 12.000<br>
13.000 14.000 15.000 16.000<br>
<br>
As you can see there is a HUGE difference in the hard case, while the easy case
remains ok. The precision of the decimal outputs is clearly a user preference
sort of thing - maybe we could even make some options for the formatting? That
may be hard to do in the PrintSelf sort of framework though..<br>
<br>
Thoughts?<br>
<br clear=all>
Thanks,<br>
