Preserved Topic: Shading Basic Objects Examples Wanted

I have been spending a good deal of time on google trying to find examples of how to shade different objects. The only good result I found was for a sphere, with the link I am providing below.

http://homepages.tesco.net/~p.wilkinson/BlendShade.htm

I am looking for something similar to the final image ( http://homepages.tesco.net/~p.wilkinson/ball5.gif ) for other basic objects.

Cube
Cone
Cylinder
Pyramid

I was unable to find information on how the shading would work for these objects. I know I could fudge it based on inspection but I am sure that there are people who have studied these shapes and know the details about shading these shapes. I am interested in anything you might be able to give me on this.

The reason I am looking for examples is that I want to start from the beginning on my shading in a digital imaging program using low opacity painting. I have created a sphere based on the ideas presented in the tutorial I listed above, and just want to continue with the basic practice a build off of it.

Also if you could give me pointers on my sphere I would appreciate it as well. Thanks a lot.

I wrote a long post before but i lost it

As someone else will probably probably point out, you best bet is trying to get actual objects and study them.

The thing with that tutorial you read is that it seems to be aimed to a high contrasted texture/lighting, and a single directional light source. On that matter, cilinders will get an horizontal gradation. Cones are quite similar, but its shade will get smaller as it goes up. A pyramid will sureñly have a radial gradation, but not like the sphere. I really cannot explain it.

There isn't really much science on them, really.Just observe where lights and shades are and that is pretty much all.

Your sphere needs a smoother transition to the main shade on teh right side, IMO. And try adding a few more contrastin tones.

Btw, here are a few quickies I did:



They are not the best you will ever see, but hopefully they will help.

Yeah they are very nice, and exactly what I was looking for. Thanks you a whole lot.

*Bump* Anyone willing to do a pyramid?

Ok, let's give it a try :

Excellent thanks a lot.

Ok, but I have a question. On the cube there is a band of light following the dark on the side that is removed from the light, this does not exist on the pyramid.

How is lighting suposed to affect flat sided objects?

i dunno how helpful you'll find the following link, but *i* thought it was pretty spiffy.
Perspective and casting shadows

there's also a pretty nice thread at conceptart about perspective and shading etc. i found it hella useful!

Warmage - i added a back light to the cube, just like i did with the other two objects and the sphere.

Flat sized object often get a radial gradation. In my cube it was one the top frontal corner. I think i progbably did something worng with the backlight, so I apologize.
