As I’m working to reproduce Josh’s DTLZ1 Animation that he demoed in the group meeting last week, I thought I’d write a list of my workflow here on the blog.
- Load the DTLZ1.par file from the examples folder on ANGEL
- In Edit… Plotting Preferences, go to the Glyph tab, and change the size of the glyphs to something like 0.02. You just want to change the size so you can see the points better.
- To get the axes to scale the correct way…first fast-forward the animation to the end using the animation controls.
- Then, open “Central Variable Controls”, and reset each axis to its natural scale. Lock the scaling of the axes so they don’t change by clicking “lock” on each axis.
- “Rewind” the animation to the beginning.
- In animation tools, find the pulldown menu for “Sync By”. Change the sync by option to NFE. Then, type 25000 in the “skip to” box. Any time you change something in a menu box, be sure to hit Enter on your keyboard to accept the command. This will fast-forward the animation to a point where you see some solutions appearing in the glyph cube.
- The next step will rotate the cube to show a little bit of depth for 3d. You’ll want to think about a starting and an ending point that you desire. Then, move the cube to the starting point.
- Take a snapshot using the “take snapshot” tool.
- Without moving the mouse, set an interpolation camera in “gif controls.”
- Now move carefully to the second view that you want. This will be the one you keep for the rest of the animation. Set a second interpolation camera.
- We’re ready to start the first animation! Click the red “record” button in GIF controls. Then, click the “interpolate spline” button in GIF controls. Finally, click “create GIF”
- Now the window should be at its final view for the animation of the actual MOEA search. Click “clear keyframes” in the GIF controls. Also make sure the red record button is still depressed. Finally, set the “frame skip” in GIF controls to 8, and hit enter.
- Now hit play in “Animation Controls”. You should see the Image Stack amount increasing in GIF controls.
- You can “pause” to stop the animation at any time. When complete, click “Create GIF” in the GIF controls to complete.
The animation files were created successfully! Here’s a short list of tasks in PowerPoint then to complete the exercise:
- If you wish, make your first slide with introductory points using the static version of the figure, in your Snapshots folder. The subsequent animations can be placed on different slides.
- In Image Tools in PowerPoint, make sure that each figure (the static one and the two animations) are exactly the same size. For example, round off the width of the figure to a round number, and the height should follow.
- Then, click in the bottom right corner of Image Tools to get to the size and position dialog box. In position, make each figure have the exact same horizontal and vertical position. This will ensure that the figures don’t “jump around” on screen between slides.
And that’s it!
