Simulates the random veins and impurities that naturally occur in marble. It lets you create a wide range of marble types by tweaking the parameters. The marble texture is based on the two differently colored veins sandwiched between the filler material, which are then deformed using a fractal function. You can select two colors for the veins and a color for the impurities (filler) to precisely achieve any type of marble you wish.
Selects the texture projection to use. See Specifying a Texture Projection [Texturing].
Name |
The shader's name. Enter any name you like, or leave the default. |
Type |
The algorithm for the pattern:
|
Frequencies |
Defines the frequency of the fractal in the X, Y, and Z directions. High values take longer to render. |
Amplitude |
Defines the base amplitude of the fractal used to calculate this texture. This parameter only applies to the amplitude of the first iteration; successive iterations may further increase the amplitude. |
Ratio |
Defines the amplitude of the successive iterations relative to the current one. For values less than 1, successive iterations have a lower amplitude; for values greater than 1, the iterations have a higher amplitude and the fractal becomes unbounded. |
Complexity |
The maximum number of noise iterations used when calculating the fractal. |
Absolute |
Makes the procedure use a slightly different algorithm, which introduces discontinuities into the fractal, creating the impression of turbulence. |
Color parameters can be connected to other textures or image processing shaders. A texture's scalar parameters can be altered to create interesting effects by applying Texture Generator shaders to them. For example, the Vein Width factor can be controlled with the Fractal Texture Generator shader.
A texture shader has limitless capabilities in a render tree. It can texture an object, be used as a camera or light projection, define bump or displacement maps, or be blended with any number of other textures to create any effect.
