I was recently searching for photos of the Niagara online when I discovered
that there was a star painted on the top of the capstan. I decided this was
the perfect excuse to rework the capstan. In the process I discovered that
by applying slope to my textures, I could show wear on the edges of the
parts. I rendered this image with poor radiosity settings, but was so
pleased with the results of my texture experiments, that I decided to share
them with you. the star is a prism that is set into the black wood. All of
the textures are procedural.
Now I need to finish reworking the bottom half of the capstan and
then....rework all the wood textures using slope....this project was
originally concieved as s short project I could use to learn POV-Ray....I
am learning, but it is not a short project!
As allways, I love criticism,
Tim

So -that's- what slope maps are for... Looks nice, Tim. Maybe as you rework
the wood textures, make it the wood a wee bit rougher?

I find the textures with the worn edges extremely impressive ! Do you
mind showing an example of your slope texture ?

You really freak me out with all this detailed ship building stuff. I just
watch it being put together, when you post updates, but figured I could stop
and say something for a change...
Did you realize the boards don't have a gap all the way through? The
greenish circular part, I mean, not the deck.
Yeah, I must find fault or I don't feel complete. : )
BTW, any plans to animate a walk-through on and around the S.S. Niagara? Or
is this very slow to render?

I hope being freaked out is a good thing!

The gap is there, but very small. These boards are supposed to be butted up
against each other. I am attaching an image close up showing the fine seem
between them.

:) I would like to get a little further ahead to create an animation. i
think I will also build a web page for the entire project.
thanks for you comments Bob.

Thank you for your comments. I appreciate it. Here is a sample of the
texture.
#macro WornWood(RGB,WearFlat,WearEdge,Norm,Rot,Tran)
#declare Texture1 =
texture {
pigment {
wood
turbulence <0.1, 0.5, 1>
octaves 5
lambda 3.25
scale <0.15, .5, 1>
rotate <5, 10, 5>
translate -x*2
color_map {
[0.0 color RGB]
[0.1 color RGB]
[0.1 color 0.95*RGB]
[0.9 color 0.95*RGB]
[1.0 color RGB]
}
}
finish{
ambient 0
phong 0.35
phong_size 100
}
}
#declare TWood1 =
texture{T_Wood7}
texture {
pigment{color rgbt <255, 155, 23,
0.999999*256>/256*0.25}
}
#declare TWood2 =
texture{T_Wood7}
texture {
pigment{color rgbt <255, 155,
23,1.5*256>/256*0.45}
}
#declare PaintedWood1 =
texture{
bozo
texture_map{
[0 TWood1]
[WearFlat TWood2]
[WearFlat+0.1 Green1]
[1.0 Green1]
}
warp{turbulence 0.2}
scale <0.25,0.25,50>
}
#declare PaintedWood2 =
texture{
bozo
texture_map{
[0 TWood1]
[WearEdge TWood2]
[WearEdge+0.1 Texture1]
[1.0 Texture1]
}
warp{turbulence 0.2}
scale <0.25,0.25,50>
}
#declare DummyNum =0;
texture{
slope { <0,-1,0> }
texture_map{
[0 PaintedWood1]
//[0.1 PaintedWood1]
[0.1 PaintedWood2]
//[0.4 PaintedWood2]
[0.4 PaintedWood1]
[0.6 PaintedWood1]
[0.9 PaintedWood2]
//[0.9 PaintedWood2 ]
[1.0 PaintedWood1]
}
warp{turbulence 0.2}
rotate Rot
translate Tran
}
#end
Hope this helps.
Tim

That's some fantastic carpentry. I could use such skill IRL instead of the
haphazard way I go about it. I like how this view remains good even though
so close now.
