CONTENTS

Animation Panel

Using the Animation panel, you can create a simple fly-through animation.

OPTIONS

  (Reverse)

Moves backward through the animation one frame at a time.

  (Stop)

Stops the animation.

  (Forward)

Moves forward through the animation one frame at a time.

  (Play)

Plays the animation.

Tot. Frames

Sets the total number of frames in the animation.

Key Frames

On the Animation panel, use the Key Frames slider to display and select key frame positions. Each vertical black line represents a frame in the animation. A thick vertical blue line marks the current position (frame) in the animation. An inverted blue triangle marks each key frame above the frame markers. Click at any point in the frame markers (black lines) to move the current position. Click and drag the key frame markers (blue triangle) to a new position.

Add

Adds a key frame at the current position (frame number) marked by the thick vertical blue line.

Clear All

Deletes all key frames.

Show

Use the next three options to annotate the animation.

Path

Shows the path that the animation follows between key frames (if selected). This is useful for adjusting the tension if using a spline interpolation.

Vect

Draws all loaded vector maps in the animation (if selected).

Sites

Draws all loaded sites files in the animation (if selected).

Interp.

Sets the interpolation used between key frames.

Linear

Uses a linear interpolation between key frames.

Spline

Uses a spline interpolation between key frames at the selected tension.

Tension

Sets the tension of the spline interpolation.

Run and Save

Runs the animation and saves each frame as an image. You must supply a file name prefix, and set the image and draw type. The image file name includes the file prefix, frame number and image type. For example, frame number 12 with a file prefix of FLY saved as a PPM would be named FLY0012.ppm.

Closes the Animation panel.
