Glass Gem Corn

I saw an article about this very unusual strain of corn that has multi-colored kernals and tried to see if i could make something that hinted at it:

Bizarre! Modelling a whole ear of that would be a little tedious, although I suppose you could use the same group on multiple kernels.

Very nice look... somehow it looks like a painting too me... but a very realistic one!

 

Love it!

 

See you

A test to see if I could create the semi-random kernel arrangement by squeezing together cloth spheres.

 

The first is with low "friction", the second is with high "friction":

would you then wrap the cloth kernals around a mesh in the shape of a cob?

Haven't quite figured the cob thing out yet.

 

Perhaps one might use the dupe wizard to arrange them in a cylindrical form first

I did it brute force (copy paste, offset until I got one column, copy paste offset that , until got 4 columns, use distort, offset, make 1 quarter of cob, copy paste, flip for 4 qtrs).

 

However I didn't get the nice spiral growth pattern and I would probably use sweeper if I were to do it again (create spiral path, duplicate a kernal, copy result, offset, distort, etc)

 

Color variation was obtained by changing the surface color of the instance and % of the color decal of the cob model in the chor. I used the image of the glassgem corn for the decal, but I would also probably change the image so that the coloring would line up a bit better with the kernels on the cob model if I were to do it again. And I would close off the holes in the kernel.

Here's a test of dropping kernals into cylindrical forms:

COOL! Hey Rob- I am interested in how you got that 1st image, matcap? Is there really a 2nd form inside the 1st one?

The image is a combination (done in an A:M Composite) of these two:

 

 

The dark one has AO. For some reason I couldn't get either FakeAO or Real AO to get what I wanted so i tried combining two exposures. It's still not what I was aiming for. Then I blurred it by 2 pixels (also in A:M Composite)

 

 

There is indeed a 2nd form, the white "seed" of the kernel. That was the tricky part to try to reproduce from the original photo. I made it blurry by sweeping the Index of refraction of the outer surface over a multi-pass render. Without that, the unsatisfying result is like this:

Nice.
