3D textures
Shared 3D texture attributes
Wood
Simulates wood by projecting a 2D pattern.
This pattern consists of concentric ring layers defined by veins
and filler. When you map the Wood texture to
a surface, the surface seems to be carved out of wood. When you
map it to several surfaces, they seem to be carved from a single
block of wood.
Find this texture in the
Create bar.
To apply this texture as a texture map, see
Map a 2D or 3D texture.
Tip
- There
are four Wood attributes that are frame
constant, meaning that mapping them with textures or other nodes
that produce different values from point to point may lead to unpredictable
results. These attributes are: Grain Spacing, Layer
Size, Randomness, and Age.
You can key all of these attributes to make their appearance change
over time in an animation sequence.
- If
you use the Wood texture as a bump map,
lower the Grain Contrast setting to reduce
the potential for texture artifacts during animation.
- Filler Color
-
The
color of the space between veins. The vein color diffuses into the
filler color. Double-click the color bar to choose a different color
from the Color Chooser.
- Vein Color
-
The
vein color of the wood. The vein color diffuses into the filler
color. Double-click the color bar to choose a different color from
the Color Chooser.
- Vein Spread
-
The amount of vein color that diffuses
into the filler color. The valid range is 0 to infinity. The slider
range is 0 to 3. The default is 0.25.
- Layer Size
-
The average thickness of each layer or
ring. The valid range is 0 to infinity. The slider range is 0 to
0.5. The default is 0.02. (The thickness of individual layers or
rings is also influenced by the Randomness and Age values.)
- Randomness
-
Randomizes
the thickness of individual layers or rings. The range is 0 to 1.
The default is 0.5.
- Age
-
The
age of the wood (in years). This value determines the total number
of layers or rings in the texture, and influences the relative thickness of
central and outer layers. The valid range is 0 to infinity. The
slider range is 0 to 100. The default is 20.
- Grain Color
-
The color of the random grain in the
wood.
- Grain Contrast
-
Controls
the amount of Grain Color that diffuses into
the surrounding wood color. The range is 0 to 1. The default value
is 1.
- Grain Spacing
-
The average distance between grain
spots. The range is 0.002 to 0.1. The default value is 0.01.
- Center
-
The
location of the center of the texture’s concentric rings in the
U and V directions. The range is -1 to 2. The default values are
0.5 and -0.5.
TipDo not set the Center values
less than -3 or greater than 3.
Noise Attributes (Wood)
The Wood texture
creates a 3D texture by projecting a 2D pattern. The Noise Attributes control
the randomization (using fractal noise) of the texture in the direction
the pattern is projected. Select from the following:
- Amplitude X, Amplitude
Y
-
An
average scaling factor applied to all values in the fractal noise
in the texture’s X and Y directions. The valid range is 0 to infinity.
The range is 0 (no noise) to 1 (strong noise). The default value
is 0.1.
TipThe Wood texture
renders faster if the Amplitude X and Amplitude
Y values are both 0.
- Ratio
-
Controls
the fractal noise frequency. The range is 0 (low frequency) to 1
(high frequency). The default is 0.35.
- Ripples
-
Determines
the texture’s waviness in the X, Y, and Z directions. The values
represent the frequency scale of the fractal used to generate the
texture. The range is 0 to 20. The default is 1.
- Depth
-
The minimum and maximum number of iterations
used to calculate the texture pattern. This parameter controls how
fine grained the texture is. The range is 0 to 25. The default values
are 0 and 20.
