A variation of the
flagstone pattern forms the Veins texture. By combining multiple
layers of connected lines, this function renders leaf textures and other
The number of veins layers is
defined by the Octaves parameter. Higher octaves feature
smaller veins than lower octaves. By decreasing the Persistence
attribute, you can fade out the higher octaves. Increase the Resolution
parameter to reduce the overall vein size.
By setting the Persistence value to greate than
you can abuse the function to create plaster-like textures.
Regulate the intensity of the
veins with the Amplify value.
Change the Random Seed
attribute to get a different veins pattern.
You can animate the three-dimensional veins texture by increasing
the Time Offset value. This will move the virtual camera
along the z-direction into the texture. After 1000 time
frames you will reach the starting point again.
