Overview:

The Noise POP uses a noise field to change or create attributes for every point in its input, and can be used to add randomness to our points. By default, the Noise POP will move a point’s P attribute in X, Y, Z based on the point’s position in the noise space. We can use the Amplitude and Exponent parameters to adjust the magnitude of the resulting noise values.

In addition to the default parameters found on other Noise operators in TouchDesigner (like the Noise TOP or Noise CHOP), the Noise POP’s Output page contains additional mathematical functions that can be derived from the noise field, i.e. Gradient and Curl noise.In this topic, we can see how we can apply noise to a Line POP, use a Grid POP as the input for our Noise POP to visualize the noise field, and toggle on the normals for our noise.
