Houdini 16.5 Nodes VOP nodes

Random VOP node

Generates a random number based on the position in one, three, or four dimensions.

This operator generates a random number based on the position in one, three, or four dimensions. Unlike the noise functions, which smoothly interpolate the random values between integer lattice points, this random number generator does not. Each number is in the [0..1) range.

In the Signature parameter refers to the types of the inputs and outputs. Color and vector are 3 floats, and points are four floats.

Note

This VOP only produces different numbers for each integer value of the input, not for each float value like the VEX hscript_rand does.

Turning off the Clamp Position to Integer Values will give different results for different inputs, but be warned that very small floating point differences will then have big changes in the result.
