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.
