Display Options

Determines which fcurves are displayed in the graph by default:

• Show None displays no fcurves for the selected object.

• Show All Parameters displays fcurves for all parameters of the selected object.

• Show Animated Parameters displays fcurves only for the object’s animated parameters.

• Show Marked Parameters displays fcurves only for the object’s marked parameters.

• Show Selected Parameters displays fcurves only for the object’s selected parameters.

Allow selecting curves from the tree in Selected Mode

When the View > Selected Parameters command is active in the fcurve editor and you select a parameter in the animation explorer, its fcurve is also automatically selected. This makes it easy to edit and manipulate the fcurve immediately.

Deselect this option if you want to display the fcurves, but not select them, when you select a parameter in the animation explorer.

Display Grid

Sets the spacing between grid lines on the X (Time) and Y (Value) axes. Show displays or hides the X and Y axis grid lines.

Snap Grid

Sets the interval on the grid’s X (Time) and Y (Value) axes to which a key will snap when it is moved or created. Snap toggles the snap-to-grid feature on and off.

Snap Slope

Sets the Length in Softimage units or the Angle in degrees to which slope handles on key points will snap when manipulated. Snap toggles this option on and off.

Show X /Show Y

Show displays or hides the rulers on the horizontal X (time) and vertical Y (values) axes.

Select Tool

Selects and moves function curves, keys, and slope handles.

Select Curve Tool

Selects only function curves.

Select Key Tool

Selects only keys.

Select and Move Key Tool

Selects and moves keys.

Interaction Lag

The number of pixels a mouse moves before interaction begins. You can decide on how fine you want the control when moving points and slope handles on key points.

Key Coordinates

Displays the X and Y coordinate values for each selected key.

Slopes on Unselected Keys

Displays the slope handles of all points on a selected function curve. When off, only the slope handles of selected keys are displayed.

Keys on Unselected Curves

Displays the keys of all displayed function curves. When off, only the keys of selected function curves are displayed.

Snapshot Curves

Displays a temporary copy, or "snapshot," of the original function curve. When moving a key or part of a curve, a snapshot of the curve’s original location is created.

Pan & Zoom Tool Mode

Choose either the Pan & Zoom or Zoom (rectangular selection) tool to be the default zoom mode.

Time Cursors Visible

Toggles the display of the red playback cursor in the animation editor.

Time Cursors Selectable

Toggles the selectability of the red playback cursor only in the fcurve graph. The playback cursor is always available in the animation editor’s timeline, if visible.

Auto Frame Curves

Toggles the automatic framing of an object’s fcurves in the graph when you open the animation editor or when you update the selection.

If you have the View > Selected Parameters filter active for the fcurve graph and you select one or more parameters in the animation explorer, their fcurves are automatically framed in the graph.

Interactive Update

Toggles the Edit > Interactive Update command in the fcurve editor and controls its refresh speed.

Express slopes as ratio as in SI|3D

The slope angle text boxes in the fcurve editor command bar display the handle values as a ratio of Y values over X values.

Apply spline/linear interpolation to both sides of selected keys

Does as advertised! When you select keys on a curve and select either spline or linear as the interpolation type, the same interpolation is used on the slopes on both sides of the keys.

Time Step

Specifies at what interval keys will be inserted when using the resampling option.

Keep Existing Keys

Keep keys that existed before adding keys through the resampling option.

Average Filter

Smooths the function curve by applying a moving average. The weights of the averages are uniformly distributed.

Gaussian Filter

Smooths the function curve by applying a moving average. The weights of the averages are distributed as a bell curve. This usually gives better results than the average filter.

Filter Size

Defines the number of keys that are averaged to calculate a new key. A high filter size will yield a much straighter curve.

Variance

For the Gaussian filter only. Controls the degree of smoothing. A higher variance smooths the function curve more.

Tolerance

Adjusts the closeness of the fit. Smaller values will respect the original shape of the curve more by using more keys, while larger values will use less keys and result in a fit that deviates from the original curve.

Resample Before Fitting

Resamples the curve before the fit is applied using the value set for the Resample - Time Step. This is useful for fitting on low-density fcurves.

Ripple Mode

Existing keys on the function curve will be pushed to the right on the timeline after the insertion point of the pasted keys.

Selecting this option is the same as clicking the Ripple icon or choosing Edit > Ripple in the fcurve editor command bar.

When Pasting

Determines whether the pasted keys will merge with or replace existing keys on the fcurve:

• Merge Keys: The pasted keys are merged with any existing keys on the fcurve that at the same frames.

• Replace Keys: The pasted keys replace any existing keys on the fcurve that are at the same frames.

Paste Mode

Determines the value of the pasted keys:

• Absolute—The pasted keys completely overwrite the equivalent area on the fcurve.

• Relative—The keys are pasted in relation to the first key in the paste region.

Legacy Cut/Copy/Paste

Allows you to cut or copy and paste fcurves and keys across multiple instances of Softimage. However, you can cut/copy and paste from only one fcurve at a time.

Use Average

Inserts a key at the left of the paste region by taking an average of the values of the copied and original curves at that point.

Use Left Value

Inserts a key at the left of the paste region by using the value of the original curve at that point.

Use Right Value

Inserts a key at the left of the paste region by using the value of the copied curve at that point.

Use Average

Inserts a key at the right of the paste region by taking an average of the values of the copied and original curves at that point.

Use Left Value

Inserts a key at the right of the paste region by using the value of the copied curve at that point.

Use Right Value

Inserts a key at the right of the paste region by using the value of the original curve at that point.

Audio Waveform Display

Toggles the display of the waveform in the graph.

Audio Waveform Display Area

Determines how much of the fcurve graph area the waveform covers. The waveform is always drawn starting from the upper-left corner of the graph.

By default, the waveform is displayed using 100% of the fcurve graph. If you change the amount of display area to take up, say 50%, the waveform is drawn at half the original height, but also shifts up in the graph.

Mixer Audio Clip

Shows the full path of the current audio clip being displayed (such as Mixer.Mixer_Audio_Track.Clip). You can enter a new path or delete this field to clear the audio clip.

Show Audio Markers

Toggles the display of any markers associated with the audio clip. The marker display level is also taken into account and displayed accordingly.

These markers are for display purposes only, so you cannot select or move them.

Audio Marker Min Drawing Level

Determines the limit of how high the smallest level of markers is drawn. The lower the value, the higher up in the graph they are displayed.

Audio Marker Max Drawing Level

Determines the limit for how low the largest level of markers is drawn. The higher the value, the lower down in the graph they are displayed.

Show Labels

Toggles the display of the marker’s value at the bottom of the marker. These values are any labels you have added to the marker to identify it. Values are set in the marker’s Marker property editor.

Show Duration

Toggles the display of the marker’s duration in frames. The duration appears as a gray box on the marker covering the appropriate number of frames.
