Hi,
I think I found a little bug in the wood.inc include file. When I render
the texture T_Wood12 I get strange patterns. Have a look at the
attachment please. The problem is caused by the two textures that are
overlayed in the definition of T_Wood12 in woods.inc. Rotating one
texture by 90 degrees on the y-axis solves this. So I searched deeper in
wood.inc and found the definition of the wood grain:
#declare P_WoodGrain12A =
pigment {
bozo
turbulence 0.04
lambda 2.5
omega 0.1
octaves 7
scale <0.5, 0.05, 0.05>
}
The scaling of 0.5 for the x-value should be 0.05 and the scaling for
the z-value should be 0.5. Then everything looks o.k. without rotating
one texture.
I hope this makes any sence. :-)
So long,
Bonsai
