sWood Texture Parameters
- Filler_color
-
The
color of the space between veins. The vein color diffuses into the filler
color.
- Vein_color
-
The color of veins in
the wood. The vein color diffuses into the filler color.
- Vein_spread
-
The amount that the vein
color diffuses into the filler color. The valid range is 0 to infinity.
The slider range is 0 to 3. The default value is 0.25.
- Layer_size
-
The average thickness
of each layer or ring. (The thickness of individual layers or rings
is also influenced by the Randomness and Age values.)
The valid range is 0 to infinity. The slider range is 0 to 0.5.
The default value is 0.02.
- Randomness
-
Randomizes the thickness
of individual layers or rings. The valid/slider range is 0 to 1.
The default value is 0.5.
- Age
-
The age (in years) of
the tree from which the wood came. The Age value
determines the total number of layers or rings in the texture, and
influences the relative thickness of central and outer layers. The
central rings of wood are thinner than the outer rings because a
trees’ growth is slower when it is young. The valid range is 0 to
infinity. The slider range is 0 to 100. The default value is 20.
Grain Parameters (spots)
The Grain
Parameters (spots) control the appearance of random grain
in the wood (which appears as spots in the texture’s cross-section).
- Grain_color
-
The color of the random
grain in the wood.
- Grain_contrast
-
Controls the amount that
the Grain_color diffuses into the
surrounding wood color. The valid/slider range is 0 to 1. The default
value is 1.
- Grain_spacing
-
The average distance
between grain spots. The valid/slider range is 0.002 to 0.1. The
default value is 0.01.
Concentric Ring Location
- Center_u, Center_v
-
The
location of the center of the texture’s concentric rings in the
U and V parametric directions. The slider range is -1 to 2. The
default value is 0.5 for Center_u and
-0.5 for Center_v.
TipDon’t
set the Center_u or Center_v value
less than -3 or greater than 3.
Noise Parameters
The sWood texture
creates a three dimensional texture by projecting a two dimensional
pattern. The Noise Parameters control the
randomization (using fractal noise) of the texture in the direction
the pattern is projected.
- Xamplitude,Yamplitude
-
A scaling factor applied
to all values in the fractal noise about the average value, in the
texture’s X and Y directions. The sWood texture
is rendered more quickly if the Xamplitude and Yamplitude values
are both 0. The valid range is 0 to infinity. The slider range is
0 (no noise) to 1 (strong noise). The default value is 0.1.
- Ratio
-
Controls the frequency
of the fractal noise. The valid/slider range is 0 (low frequency)
to 1 (high frequency). The default value is 0.35.
