TS_SurfB
Surf creates a wave pattern with the option of damping the amplitude of the waves as they approach the beach.
Parameters
Scale These three controls scale the shader in the X, Y and Z axis. The bigger each of the values the smaller the shader pattern will appear.
Center These three controls position the center of the shader in the X, Y and Z axis. It is possible by moving the shader center over time to create swirling noise animations.
Bump Height This parameter determines the height of the bumps when positive or the depth of the pits when negative.
Bottom Clip This parameter sets the clipping depth of the bumps. That is, the point down the bump slope where it is clipped and flat plateau rendered.
Top Clip This parameter sets the clipping height of the bumps. That is, the point up the bump slope where it is clipped and flat plateau rendered.
Disturb The shader can be stirred up, or disturbed, using a turbulence function with these three values controlling it. The three values control the Magnitude, Scale and Number Of Octaves respectively. The Magnitude value controls the size of the shader disturbance. For turbulence to be generated this must be greater then zero. The larger this value the more disturbed the shader is. The Scale value controls the frequency of the shader disturbance. The larger this value smaller period of the turbulence and therefore, the finer the shader disturbance. The Number Of Octaves value controls the number of noise summing used in the shader disturbance. The higher this value the more octaves and the finer the detail of the disturbance will be become.
Wave Type This control allows one of six different shader wave types to be used. By passing the shader function through a waveform generator different shader patterns can be created. The wave types are 1 for Saw Tooth, 2 for Sine, 3 for Cosine, 4 for Scallop, 5 for Smooth Step, 6 for Triangle and 7 to Invert. These are shown below:

Stencil Image The stencil image is an image that can be used to control the bump height. When the stencil image is used the brightness in-conjunction with the Bump Height determine the scaling of the bumps at any point.
Stencil Image The parameter controls the use of the stencil map. When the value is 0.0 the stencil image is not used. When the value is 1.0 the bumps will be scaled such that when the image is brighter the bumps will be higher. Conversely, when this value is -1.0 then image is negated so that the bumps will be highest where the image is darkest.
Axes This parameter sets the axis along which the waves are drawn. A value of 0.0 sets the X axis, 1.0 the Y axis and 2.0 the Z axis.
Direction This parameter sets direction in which the waves are dampened.
Damping The parameter controls the damping of the waves. This is, the length over which the amplitude of the waves is reduced. The larger the value the more quickly the waves are dampened.
Frequency This parameter sets the frequency or period of the waves. The larger the value the more waves.
Phase This parameter controls the phasing of the waves. The value can be animated in order to make the waves roll.
