  POV-Ray 3.7: Symmetry Compromised? (Message 1 to 9 of 9)

The antennas on the right side should be identical to the antennas at the left
side, but they aren't. Unless I miss to discover since several hours an error on
my side, I think, I have discovered a serious programming fault in the new
POV-Ray 3.7.

Please test my scene source code and give me a feedback. Thanks.

On a side note: it seems I also discovered another programming fault: when
animating (clock), the final video show some sort of black vertical line (a
cut-out?) where nothing is supposed to be. Please view here the video:

The fault is all yours.

Replace:

     box { < -62.5, -200.0, -325.0 > < -61.0, 200.0, -300.0 > }

by:

     box { < -62.5, -200.0, -500.0 > < -61.0, 200.0, -300.0 > }

in your difference block and all is symmetrical.

Sometimes, so it seems, it's hard to see the forest because of all the trees...

I do agree indeed. I plodded along that same road so many times... :-)

That's why I used a modeling program instead. But that has its own issues too.
