This is based on an image posted here about six months (?) ago. The original
artist may recognize that I ripped his idea off...
The twirly thingy is stolen directly (and shamelessly) from Friedrich
Lohmueller's excellent Pov tutorial pages.
The same old dead horse (maybe) but I think at least the colors look nice.
K'pla!

It looks nice!
But you have rendered a square image with a 4:3 aspect ratio, which has
stretched the image. To use a 1:1 aspect ratio, you can set...
up y
right x
...in the camera definition.

Eh? Here's my camera def:
camera { // Camera SceneCam
location < -11.316, -14.102, 7.067>
sky < 0.00000, 0.00000, 1.00000> // Use right
handed-system
up < 0.0, 0.0, 1.0> // Where Z is up
right < 1.34707, 0.0, 0.0> // Right Vector is
adjusted to compensate for spherical (Moray) vs. planar (POV-Ray) aspect
ratio
angle 30.00000 // Vertical 22.500
look_at < 0.485, -0.151, -1.601>
}
(obviously the boilerplate one from Moray). I rendered the image in
1280x1024 - the aspect seems correct on my monitor here...? Or is 1280x1024
the culprit?
Or am I just being daft?
Sorry but I'm still relatively new to Pov and I've never had to bother with
fixing aspect ratios...
Thanks for take a peek at the image!
Regards,

Looks like one of your floor blocks has been marked for death by pirates.
;-)
PS nice.

Thanks - that was a slip with gimp when I was saving the image from tga to
jpeg after rendering - I accidentally had a brush tool "misfire"...:)

Aha. That happens to me too. Stupid hair-trigger gimp tools :)

To tell the truth, neither can I see anything wrong with this image...
Nice one Stefan!

It should be
right < 1.25, 0.0, 0.0>
I thought at first that the image was square, but it is in fact 1280x1024
which is 5:4 aspect ratio. However, your camera definition uses a 4:3 aspect
ratio, which stretches the image slightly. See the attached image. If you
change the right vector in the camera to the one above, the image will not
be stretched anymore.

Ok, thanks!
I'll remember that when rendering in 1280x1024 in the future.

Bedankt, Thomas! Interessant om 'n Nederlander hier te sien. Hoe se julle
daar? Erg Leuk!
Groete vir die kaaskoppe
