This patch returns the current state of the tablet pointing device. The pen position is expressed in units in the Quartz Composer coordinates system. The pen tilt on the X and Y axes is normalized to the [-1.0,1.0] range and the pen pressure is normalized to the [0,1] range. Note that this patch does not read the tablet state directly but is dependent on the proper information being passed to the composition. This information may not always be available, depending on the environment in which Quartz Com... more...

This patch allows you to define an arbitrary set of curves that are evaluated at a given time. more...

This patch generates random values in a given range. The variability of the generated random values can be set in the patch's settings. more...

This patch returns the current state of the mouse pointing device. The mouse position is expressed in units in the Quartz Composer coordinates system. Note that this patch does not read the mouse state directly but is dependent on the proper information being passed to the composition. This information may not always be available, depending on the environment in which Quartz Composer is running. more...

Given a position, the Noise patch outputs a random value based on a Perlin distribution. The noise produced is deterministic and safe to use inside an iterator. more...

This patch interpolates between two numerical values over time. The curve used for the interpolation can be chosen among presets (linear, quadratic, exponential...) or defined manually through a cubic spline using up to 16 control points. The duration of the interpolation and its looping mode can also be specified. more...

This patch returns the current state of a customizable list of keys of the keyboard device. Each observed key is represented by a boolean output set to True when the key is down and False otherwise. Because the keys are actually observed through the character they produce, key modifiers (like [Shift], [Control]...) matter: for example, 'Q' is considered different than 'q'. Note that this patch does not read the keyboard state directly but is dependent on the proper information being passed to the compo... more...

This patch generates a low-frequency oscillation. All the parameters of the wave used for the oscillation can be customized: type, period, phase, offset and amplitude. The minimum and maximum values reached by the wave are defined by (offset - amplitude) and (offset + amplitude). more...

This patch returns the current state of a list of observed elements of a connected HID compliant USB input device. more...

This patch returns the current state of the Apple Remote. Note that even if the host computer is compatible with the Apple Remote, the remote might not necessarily be accessible. more...
