Timeline 3D for OS X Yosemite Beta

Wednesday, October 22, 2014

Last week, Apple released OS X Yosemite and I published the first beta of new the new Timeline 3D for OS X Yosemite. After you upgrade your Mac, please try the new Timeline 3D.


The beta will be free while I iron out the bugs and put the finishing touches on the iOS 8 product that goes with it. This is a good time to send me feedback about any bugs you find.

Why the rewrite?

The new version is an almost complete rewrite of the code base (the last rewrite of this scale was the “T2” release back in 2007). I have been working on this release for about three years. Some of the features have found their way into the iOS releases during that time.

A few people asked for more details on why a rewrite was necessary. The main reason is that the iOS version and the Mac version of Timeline 3D shared about 5% of their code base and the other 95% was different for each platform. This is because the Mac version was written before iOS existed and many of it’s technologies are not available on iOS. It is difficult for me to develop new features and fix bugs when the products are completely different behind the scenes.

The new versions have about 85% of the code in common. All of the date parsing, document storage, layout, rendering, and exporting code is now common. For example, when I recently improved the way date parsing works in Chinese, that improvement was applied to both platforms.

In this effort, and also in the effort to remove my dependence on technologies that have been deprecated or fallen out of favor, I swapped out many of the core technologies for newer technologies.

Here are some of the frameworks that were major components of Timeline 3D and have now been removed:

  • Core Data
  • Quartz Composer
  • Garbage Collection
  • Quicktime

In their place, I have added modern Apple technologies such as:

  • iCloud compatibility
  • Auto-saving with versioning
  • OpenGL
  • Automatic Reference Counting (ARC)
  • AVFoundation
  • Sandboxing

Obviously, the user interface has changed quite a bit too. I’ve discussed some of those changes on this blog. The main idea behind the changes is to address the most common issues customers have as well and standardizing on a user interface that can scale from phones to 5k iMacs.

If you have any questions or concerns about the new version, please send me an e-mail. I realize that it will be a transition and will cause some inconvenience, but I hope that the new architecture will serve us all well for the next 5-10 years.
