Description
theo's #1133 made me think about ways that i use noise regularly that might also be abstracted.
i would also like to see versions of noise that return multidimensional results. normally i do something like:
ofVec2 a(ofSignedNoise(t, 0), ofSignedNoise(0, t)); // 1D -> 2D
ofVec2 b(ofSignedNoise(x, 0), ofSignedNoise(0, y)); // 2D -> 2D
ofVec3 c(ofSignedNoise(t, 0, 0), ofSignedNoise(0, t, 0), ofSignedNoise(0, 0, t)); // 1D -> 3D
ofVec3 d(ofSignedNoise(x, 0, 0), ofSignedNoise(0, y, 0), ofSignedNoise(0, 0, (x + y) / 2)); // 2D -> 3D
and it would be good to spend some time making sure these are really good ways of doing it, then implement them inside some functions like ofSignedNoise2() and ofSignedNoise3() (for example).

Research direction
Start by reviewing the existing ofSignedNoise functions and the examples in the issue. The proposed work needs agreement on useful multidimensional outputs and APIs such as ofSignedNoise2() and ofSignedNoise3(); done means an agreed design and implementation, but no files or tests are identified here.
