Externals for Max/MSP/Jitter

Currently only available for Mac OS X 10.5 or later (Intel). The following have only been tested on Max 5 (32-bit).

ri.Lorenz MSP objects
Calculates the Lorenz dynamical system and various modifications at signal rate. Can be controlled by either floats or signal for sample-accurate timing.

Includes the following externals:
ri.lorenz~ the original Lorenz
ri.lorenz.complex~ the Lorenz in the complex plane
ri.lorenz.mod~ a modified Lorenz
ri.lorenz.stenflo~ the Lorenz-Stenflo

ri.rotatexyz MSP objects
Calculates 3D coordinates after rotation around the x, y and z axes by performing matrix (mathematical, not Jitter) multiplication at signal rate. Ideal for generating signal rate panning data for use with the rotatexyz message to

Includes the following externals: transforms coordinates according to angles of rotation
ri.rotatexyz.xyz5~ transforms 5 sets of coordinates according to angles of rotation
ri.rotatexyz.matrix~ converts 3 angles of rotation to 3×3 rotation matrix
ri.rotatexyz.calc~ transforms coordinates according to 3×3 rotation matrix
