Animate

Wolfram Kernel

Execution environment

wljs-manipulate

Package

Animate[expr_, {u_Symbol, min_, max_}, opts___]

Animate[expr_, {u_Symbol, min_, max_, step_}, opts___]

generates a version of expr allowing automatic repeated reevaluation for each u though min, max with a defined frame rate.

warning

Avoid animating many frames of Plot or Plot3D using such expression and consider AnimatePlot instead.

For example

Animate[Row[{Sin[x], "==", Series[Sin[x], {x,0,n}], Invisible[1/2]}], {n, 1, 10, 1}, AnimationRate->3]

Portability

The same as for Manipulate, i.e. can be fully exported as Dynamic HTML

Options

AnimationRate

Specifies frames per second. The default is 6

AnimationRepetitions

The default is Infinity

"TriggerEvent"

Specifies an EventObject used to start an animation (or restart) externally (via a button for instance)

"UpdateFunction"

Allows to alter the data generated on update or cause user-defined side-effects. The following values are expected

Function[u,
	(* side effects *)
	(* RETURN *)
	True <- accept change
	False <- prevent default
	_String <- will be written instead
]

One can bypass the default method completely and rely on side effects

Module[{pts},
  Animate[Graphics[{
    Circle[{0,0},1],
    Red, Point[pts // Offload]
  }, ImageSize->Small], {t, 0, 2Pi, 0.1}, "UpdateFunction" -> Function[t,
    pts = {Sin[t], Cos[t]};
    False
  ]]
]
