Random Gaussian

Generates a random numeric value using a Gaussian (i.e. normal) distribution. The shape can be controlled with two inputs: “Mean” and “Standard Deviation.” These inputs can be numbers, vectors, tuples or arrays of these. If one input has a higher dimension than the other, then the input with the lower dimension will be repeated to match the dimension of the other input (broadcasting).

Installation

To use this node enable omni.graph.nodes in the Extension Manager.
