Ref15-003.png

Interlace Pull-down Menu

If an option other than None is selected, rendering is performed using interlacing. Two types of interlacing are provided: Upper Field First and Lower Field First.

Ref15-004.png

Drop-frame Checkbox

Set this checkbox if you want to display the Time Code based on a frame rate of 30fps instead of 29.97fps (NTSC standard frame rate).

Auto Scaling Checkbox

When changing the total number of frames with the Auto Scaling checkbox turned on, the relative relationship of all Sequence Key Points and Motion (Key) Points to the total number of frames is maintained. For instance, if the total number of frames is 200, and the frame numbers of certain Motion Points are set to 99 (the 100th frame) and 199 (the 200th frame), changing the total number of frames to 300 will also change the frame numbers of those Motion Points to 149 (the 150th frame) and 299 (the 300th frame) respectively. When changing the Total Frames setting,switch on the Auto Scaling checkbox to allow the Motion Curve and Points to proportionately expand or contract. If you change the Total Frames setting with the Auto Scaling checkbox off, the frame numbers of the Sequence Key Points and Motion (Key) Points will not change. If the Total Frames setting is reduced below that of some of the Points, Sequence Key Points and Motion (Key) Points that no longer fit within the (active) Motion box display or the Motion List will remain as they are. They can be modified again when the Total Frame setting is expanded to include them.

Sequence Checkbox

Turning on the Sequence checkbox brings the program into the Sequence mode, where the objects displayed in the Figure window are linked with the states of the Joint components defined in the Motion window. Turning off the Sequence checkbox will exit from the Sequence mode to return to the original mode.

Auto Key Checkbox

Turning on the Auto Key checkbox places you into the Auto Key mode. Uncheck this checkbox to exit from the Auto Key mode. In the Auto Key mode, when you perform certain operations on joints, new sequence keys and motion points are created (if they are not present), or updated (if they are already present).

Sequence Ruler

The Sequencer Ruler with numbers and tick marks serves as a rough guide to Sequence Values.

The Sequencer Ruler becomes active when the mode is Sequence. When in the Current mode, click in the Sequence Ruler to switch to the Sequence mode. By default, one dot on the Sequence Ruler is equivalent to one frame.

Sequence Cursor

The Figure window display can be changed by moving the Sequence Cursor, which specifies a frame number and applies the corresponding Sequence Joint values.

The Sequence Cursor moves to the position where the Sequence Ruler is clicked, which corresponds to a particular Sequence value. The Sequence Cursor can be dragged, and the current Sequence value will change along with it. The Sequence Cursor appears on the Sequence Ruler as a triangle pointing down.

When the Sequence value of the Sequence Cursor corresponds with a Sequence Key, then the Sequence Ruler becomes active, and the triangle becomes black. When there is no corresponding Sequence Key, then the Sequence Ruler is inactive, and appears blank. A vertical line appears at the position of the Sequence Cursor in the Motion box and the Motion List.

Sequence Key Box

Sequence Key Points can be displayed, selected, created, deleted, moved, and move/copied in the Sequence Key box.

Motion Display Button

The Motion Display button is displayed as a triangle pointing downward while the Motion box and the user interface for Motion Point settings (for example, the Joint Value slider and the Ease in slider) are displayed. When the Motion Line is displayed, the triangle points to the right.

Switching to the Motion box display is also called “Opening the Motion Line,” and switching to the Motion Line display can be called “Closing the Motion box.”

Joint Value Slider

The Joint Value slider is a tool for intuitively modifying the Joint Values of Joint components. This slider is not available for Ball Joints and Cameras.

The Joint Value slider is called the Sequence Joint Value slider when in the Sequence mode, and the Current Joint Value slider when in the Current mode. A Joint value can be defined within the range restricted by the Joint Value upper and lower limiters. The Joint Value slider is displayed when the selected object is a Joint component.

Joint Value Text Box

The Joint Value text box is active for all Joints except Ball Joints, displaying the Joint Value of the Joint selected in the Motion window. You can enter a Joint Value in the text box. For Ball Joints and Cameras, this text box is not available.

The Joint Value text box is also called the Sequence Joint Value text box when in the Sequence mode, and the Current Joint Value text box when in the Current mode.

If a value outside the range defined by the Joint Value upper and lower limiters is entered, slightly drag the Joint Value slider or the Motion Point to reset the entered value to the threshold. Drag the Joint Value limiter to define the threshold (upper limit or lower limit). When the Joint Value slider is in the positive area (upper half), an entered number is recognized as a positive value, and when in the negative area (lower half), a negative value. Once you have entered a value with the “-” (minus) or “+” (plus) sign, it remains effective until you enter a value with the other sign. The Joint Value text box is displayed and active when the selected object is a Joint component.

Sequence Value Text Box

The Sequence Value text box shows the Sequence Value of the selected Motion Point in the form of a Frame Number or Time Code. A Sequence Value can be entered in this text box.

The Sequence Value text box is displayed while the Motion box is open and becomes active when a Motion Point is selected.

Range Checkbox

Switching this checkbox on will display the joint value limiters, with which you can set limits to the joint values and motion curves. No limit will be set when this checkbox is off.

This checkbox is linked with the Range slider in the Object Info window.

Auto Smooth Checkbox

Switching this checkbox on will smooth the motion curve automatically. Switching this checkbox off will not apply auto smoothing.

Corner Checkbox

Switching the Corner checkbox on results in a sudden change in the motion; smooth changes can be obtained by switching the checkbox off. The Corner checkbox is enabled when one Motion (Key) Point is active in the active Motion box.

Click the Corner checkbox while pressing the Ctrl or Z (Win) / + (Mac) to apply the setting of this checkbox to all Motion Points linked to the selected Motion Point.

Ease In Slider

The Ease in slider controls how motion flows from the previous Motion (Key) Point, with respect to the selected Motion (Key) Point in the active Motion box. The greater the Ease in slider value, the slower the motion starts. The motion stops temporarily on the Motion (Key) Point at the maximum value. The Ease in slider is enabled when one Motion (Key) Point is active in the active Motion box.

Ease Out Slider

The Ease out slider controls how motion flows from the active Motion (Key) Point to the next Motion (Key) Point. The greater the Ease out slider value, the slower the motion flow into the next Motion (Key) Point. The motion exits into the next Motion (Key) Point from the stationary state with the maximum value. The Ease out slider is enabled when one Motion (Key) Point is active in the active Motion box.

Active Motion Box

The Motion box, located just below the Sequence Key box, can be collapsed by clicking the downward triangle to the left of it. The Motion box is also called the Active Motion box while it is open, where you can edit the Motion Point(s) for the selected Joint component.

In the Active Motion box, Motion settings on Joints (except for Ball Joints) are visually displayed as Motion curves, which can be edited by moving the Motion Points.

Motion Box

The Motion box enables you to select, create, and move Motion Points for Joints as well as display Motion Curves. Clicking the downward triangle to the left of the Motion box will collapse the Motion box to the Motion Line. Click the rightward triangle to expand the Motion Line to the (Active) Motion box.

Motion Line

The Motion Line enables you to select, create, and move Motion Points for Joints as well as display the horizontal line that is created by projecting the Motion Curve of the Joint.

Clicking the triangle to the left of the Motion Line will expand the Motion Line to the Motion box. Click the downward triangle to collapse the Motion box to the Motion Line.

Joint Selection Box

If a part is open, all Joint names are displayed in a hierarchical structure in the Joint Selection box. A Joint can be selected by clicking its name.

Joint Names

The names of all Joints are displayed in a hierarchical structure.

Part Button

When a Joint displayed in the Joint Selection box has its child Joints, the Part button appears to the left of the name of the Joint. By clicking the Part button, the child Joints are displayed when they are hidden, or hidden when they are displayed.

Motion List

Motion box or Motion Lines which correspond to Joints displayed in the Joint selection box are displayed in the Motion List.

Motion Curves

For Joints except for Ball Joints, Motion Curves are displayed in the Motion box, representing the Motion settings visually.

Joint values change at a constant speed (no acceleration) when the Motion Curve consists of straight line segments. Joint values change at a faster rate when the slope of a straight segment is steep (closer to being vertical); they change at a slower rate when the slope of a straight segment is gentle (closer to being horizontal). When a straight segment is flat (horizontal), Joint Values do not change. If a segment line is not straight, it means that the Joint Value changes at an accelerated rate. |
