Hey, I need some help locating either a free 3d pumpkin or (better) some
help in developing a pov macro. I need something that looks quite a bit
like a real pumpkin... pumpkins aren't symmetrical.
Thanks,
Allen

Hi Allen,
By pure coincidence (not that big a coincidence as Halloween is just round
the corner) I uploaded a pumpkin to the new object collection at
http://lib.povray.org just last night. It's CSG and each segment position is
randomised a little, but you could easily randomise it more. To get a less
regular shape you could also replace the definition of Pumpkin_Segment,
which is currently a squashed sphere, with a similar but less regular shape
(e.g. Blobs with a degree of randomisation). If you need help on that I'd be
happy to oblige.
If it's not for Halloween (making it quite a coincidence) and you want a
whole pumpkin, rather than one with cut-outs for eyes, nose and mouth, you
can simply delete the holes from the CSG.
Regards,
Chris B.

Hi again Allen,
Inspired by your request, I've done a little more work on the pumpkin and
published an enhanced version (still at http://lib.povray.org).
The new version generates the pumpkin from a macro with options for how
regular the shape is, how many segments it's made of, whether to cut a
Halloween face in it and whether or not it has lights in it. I've randomised
a lot of stuff so you can call the macro multiple times within the same
scene and get different pumpkins each time. I've added an HTML document to
describe all of the optional settings available (which all have defaults).
Regards,
Chris B.

That is awesome. Thank you so much... I would have never been able to do
this. And, I don't have a good enough 3d modeler to model a pumpkin.
Kudos!

I have done a little work on this macro. The code isn't cleaned up yet, but
It is at least a start on the idea. First thing was just playing around
with the model to see what it could do. Next I started to implement the
idea I have been thinking about for a while. To change the carving on the
pumpkin, all you have to do is change the png file.
Make sure that the png is black and white, or it won't work. Here's a
photoshop tut for making pumpkin carving patterns.
1) Open Image
2) Ctrl+Shift+U De-saturates the image.
3) Image > Adjustments > Brightness/Contrast
Contrast 100%... Brightness around -50
4) Ctrl+Shift+E Flattens Image
5) Save as png
Enjoy!
