Summary[edit]
The Noise COMP generates a variety of noise patterns based on the selected noise type. More information about how the noise patterns are calculated can be found on this blog by Brian Sharpe.

Derivative Derivative - Calculates the derivative of certain noise function.
Amplitude Amp - Defines the noise value's amplitude (a scale on the values output).
Offset Offset - Defines the midpoint color of the noise pattern, the default is 0.5 grey.
Translate T - ⊞ - The Translate, Rotate, Scale and Pivot parameters let you sample in a different part of the 3D noise space. Imagine a different noise value for every XYZ point in space. Normally, the Noise CHOP samples the noise space from (0,0,0) along the X-axis in steps of 2/period. /tx /ty /tz /rx /ry /rx /sx /sy /sz /px /py /pz
By changing the transform, you are translating, rotating and scaling the line along which the Noise CHOPs samples the noise space. A slight Y-rotation is like walking in a straight path in the mountains, recording your altitude along the way, then re-starting from the same initial location, walking in a slightly different direction. Your altitude starts off being similar but then diverges.

Translate 4D T4d - When using a 4D noise type, this applies a translation to the 4th coordinate. The previous transformation parameters do not affect the 4th coordinate.
Blend Value Blend - Sets blend value for Value Perlin 2D and Value Perlin 3D.
Clamp Min Clampmin - Sets the clamp minimum for Cubist 2D and Cubist 3D Noise.
Clamp Max Clampmax - Sets the clamp maximum for Cubist 2D and Cubist 3D Noise.
Scale S - ⊞ - The Translate, Rotate, Scale and Pivot parameters let you sample in a different part of the 3D noise space. Imagine a different noise value for every XYZ point in space. Normally, the Noise CHOP samples the noise space from (0,0,0) along the X-axis in steps of 2/period. /tx /ty /tz /rx /ry /rx /sx /sy /sz /px /py /pz
