Hello.
Been trying to get a rust texture right and I think that staring at it for
so long has numbed my eyeballs. Constructive criticism requested, please!
For the record, this is made up of three textures placed into a texture_map,
turbulenced to death and scaled down teeny weeny.
Bye,
Alan.

It looks like some kind of anodized finish, or rough stone, but not much
like rust...
Um, what exactly is that thing?

Oh? Erm... Back to drawing board then.

It's a stick man thing that I'm using to teach myself inverse
kinematics/walk cycles, etc. This one only uses forward kinematics right
now as I've just built him, which was a cinch after constucting my robot. I
stumbled across this page:
http://www.css.tayloru.edu/instrmat/graphics/hypgraph/animation/walking/lear
ning_to_walk.htm
and it inspired me to have a go at animating walks. Whether I'll be
successful is another matter.
Bye,
Alan.

Rust should be more orangey. I should know, my car's covered in the stuff :(
It's worth looking at some of H.E.Day's source, I recall his "drunkpat"
image from the irtc city round had some nice rust effects.

I suggest you take a look at some real rust for reference. I have
plentty of rusty things i could scan in for you if you like.
Did you say "black & white"? ;)

Here's a photo I took last summer of a rusty handrail. Perhaps it's of some
use as a reference.

odd... I wonder why it looks computer generated.

Maybe you could try this as well.
I'm not sure how to link to other messages so I copied this from Ben Pashkes

texture_map{
[0 dirty_texture] file://?------innermost _map location
[1 shiny_texture] file://?------outermost _map location
}
}
}
Should i not have posted this code here?
Does this make it a bit clearer? The key really is just using the same
object
to reference in the proximity_pattern.
Anyway, pretty simple and general. Give it a go!
Now ijust need to test it with other objects! It wouln't be very useful if
it
just worked on spheres!

Uh oh. I was going to send a follow-up to you telling that the borders
of paint and rust look a little plastic and not so realistic. Then I
read the word "photo" :-).
