marble

Go to: Related nodes. Attributes.

The Marble texture consists of horizontal layers of one material (the Vein), sandwiched between layers of Filler material. The Vein is assumed to contain a strong pigmenting agent that crosses the boundary and diffuses into the Filler material.

Aside from the attributes listed here, Marble inherits many other attributes from Texture3d.

In the table below, important attributes have their names shown in bold in the description column.

Long name (short name)	Type	Default	Flags
amplitude (a)	float	1.5
Amplitude controls the amount of perturbation in the veins. If you set Amplitude to 0.0, the veins in the marble become perfectly flat planes. As you increase Amplitude, the veins become more irregular in shape.
contrast (c)	float	0.5
Contrast controls how much the two colors blend into one another in the areas where the vein color is diffusing into the filler color. Increase Contrast to reduce the amount of mixing. Setting Contrast to its maximum value (1.0) will produce the same result as setting Diffusion to 0. (See also Diffusion)
depth (d)	float2	0.0, 20.0
Depth controls how much calculation is done by the Marble texture. Fractal textures (such as Marble) are created by an iterative mathematical process; as the process goes over more levels, it produces a more detailed fractal, but takes longer to do so. Normally, the texture will choose a level it thinks is appropriate for the volume being rendered. You can use Depth Min and Depth Max to control the minimum and maximum amount of calculation that the texure will do.
depthMin (dmn) float 0.0 The minimum value for recursion depth
depthMax (dmx) float 0.0 The maximum value for recursion depth
diffusion (di)	float	0.5
Diffusion controls how much of the Vein Color bleeds into the filler surrounding the vein. Low values of Diffusion cause the colors to be completely separated. High values cause the vein color to spread right out through the filler material, staining it. (see also Contrast).
fillerColor (fc)	float3	1.0, 1.0, 1.0
Filler Color controls the color of the Filler material (the material between the veins) of the Marble texture.
fillerColorR (fcr) float 0.0 Filler Color red value
fillerColorG (fcg) float 0.0 Filler Color green value
fillerColorB (fcb) float 0.0 Filler Color blue value
normalCamera (n)	float3	0.0, 0.0, 1.0
The input normal
normalCameraX (nx) float 0.0 The X component of the input normal
normalCameraY (ny) float 0.0 The Y component of the input normal
normalCameraZ (nz) float 0.0 The Z component of the input normal
ratio (ra)	float	0.707
Ratio controls the Ratio of the fractal noise used to generate this texture. For best results, keep this value around the middle of the range.
refPointCamera (rpc)	float3	0.0, 0.0, 0.0
The current reference sample point that has to be shaded
refPointCameraX (rcx) float 0.0 The x component of the current sample position
refPointCameraY (rcy) float 0.0 The y component of the current sample position
refPointCameraZ (rcz) float 0.0 The z component of the current sample position
refPointObj (rpo)	float3	0.0, 0.0, 0.0
The current reference sample point that has to be shaded
refPointObjX (rox) float 0.0 The x component of the current reference sample position
refPointObjY (roy) float 0.0 The y component of the current reference sample position
refPointObjZ (roz) float 0.0 The z component of the current reference sample position
ripples (r)	float3	1.0, 1.0, 1.0
Ripples can be used to smear the material in a direction or make it wavy. (It controls the scale of the fundamental frequency of the fractal noise used in the texture).
ripplesX (rx) float 0.0 The noise along X
ripplesY (ry) float 0.0 The noise along Y
ripplesZ (rz) float 0.0 The noise along Z
veinColor (vc)	float3	0.298, 0.0, 0.0
Vein Color. controls the color of the Vwins that are sandwiched within the marble.
veinColorR (vcr) float 0.0 Vein Color red value
veinColorG (vcg) float 0.0 Vein Color green value
veinColorB (vcb) float 0.0 Vein Color blue value
veinWidth (vw)	float	0.1
Vein Width controls the thickness of the veins.
xPixelAngle (xpa)	float	0.002053
The pixel angle
