PlotToActions

Introduced

7.5

Description

Creates and returns new actions by plotting values from consecutive frames of an animation. Actions are created under models containing animated parameters matching the specified list.

Scripting Syntax

PlotToActions( [InputObj], [Name], [StartFrame], [EndFrame], [StepFrame], [FCurve Kind], [DefaultSegKind], [Fit FCurve], [Fit Tolerance], [ProcessContRots] )

Parameters

Return Value

Returns the created actions (a XSICollection object).

Examples

JScript Example

//
// This example sets up one model with a sphere and another with a cone,
// marks the local posz parameter of each primitive, plots various parameters
// to an action source for each model, and then prints out the new sources.
//

// Set up the scene.
NewScene( null, false );
var oSphere = CreatePrim( "Sphere", "NurbsSurface", "MySphere" );
var oCone = CreatePrim( "Cone", "NurbsSurface", "MyCone" );
CreateModel( oSphere, "SphereModel" );
CreateModel( oCone, "ConeModel" );

// Create a path for the sphere and cone, just to make things more interesting.
var oPath = CreatePrim( "Spiral", "NurbsCurve" );
ApplyPath( oSphere, oPath, 1, 50, 2, true, true );
ApplyPath( oCone, oPath, 50, 100, 2, true, true );

// Mark the local position parameter in Z for the sphere and cone.
SelectObj( oSphere + "," + oCone, null, true );
SetMarking( "kine.local.posz" );

// Plot the values of the marked parameter for the sphere and cone between frames 20 and 60.
// Notice that the default input is the marked parameters, so
// we do not have to specify anything for the 1st argument
PlotToActions( null, null, 20, 60 );

// Plot the local X position of the sphere and cone every frame between frames 20 and 60 
// and store the result in raw data fcurves.
PlotToActions( oSphere + ".kine.local.posx," + oCone + ".kine.local.posx",
          "ActionPosX", 20, 60, 1, 30 );

// Plot the local Y position of the sphere only every frame between frames 20 and 60
// and store the result in a standard fcurve with constant interpolation after 
// applying a fit with a tolerance of 0.1 to the plotted values.
PlotToActions( oSphere.posy, "ActionPosY", 20, 60, 1, 30, 1, true, 0.1, true );

// Once they are created, they are stored with the scene waiting to be applied
var oRoot = Application.ActiveSceneRoot;
var oModelsFound = oRoot.Models;
var iModelsCount = oModelsFound.Count;
if( iModelsCount > 0 )
{
   for( var i = 0; i < iModelsCount; i++ )
   {
       var oModel = oModelsFound.Item( i );
       var oSourcesFound = oModel.Sources;
       var iSourcesCount = oSourcesFound.Count;

       if( iSourcesCount > 0 )
       {
          Application.LogMessage( "Found the following sources in " + oModel + ":" );
          for( var j = 0; j < iSourcesCount; j++ )
          {
              Application.LogMessage( "\t" + oSourcesFound.Item( j ).Name );
          }
       }
       else
       {
          Application.LogMessage( "No sources found in " + oModel + "." );
       }
   }
}
else
{
   Application.LogMessage( "No models found in the scene." );
}
