Function.
A function is symbolized as a circle with one input slot (white circle) and
one output slot (red circle). It applies one of the following mathematical functions to the
input.
- Absolute.
- Strips the sign, leaving a positive value.
- Clamp.
- Clamps the input between a high and low value.
- Invert.
- Multiplys the value by -1. If used as the last transformation before output it effectively inverts the output.
- Sine.
- Applies the sine function to the value, trating the value as radians.
- Mask.
- Sets the output to one of two values based on whether the input is geater or less than a certain value.
- No Operation.
- Has no effect. It can be used to put the same noise through both sides of a combiner, or has a quick way to disable another function.
- Rough Scale.
- Scales the noise between two values. It's not 100% accurate hence 'rough scale'.
- Erode.
- A simple erosion simulation. Note the icon and preview does not work for this noise yet.
- Terrace.
- Applys a terracing effect, adding flat areas to the terrain.
- Rotate.
- Rotates the noise.
- Craterize.
- Applies a crater side shaped spline to the noise.
- Splinify.
- Samples the incoming nose and uses the results for control points in a spline patch.
