As such, we can easily calculate the position of any point in a circle using the two basic trig functions, sine and cosine. Fans themselves spread out in a circular pattern, typically ending in an angle less than 180 degrees. Step 2: MathĪt the core of this layout is a circle. This led to the core design idea: A fan that animates up and out on a long-press. On Android, however, I wanted to make use of our existing central context button to avoid additional UI elements. This bar appears when you're at the top of the scrollable content for the park, as shown in this screenshot. Tapping this lets you view what attractions were operating in a specified year. The rightmost button represents the time machine view.Tapping this switches to a chronological view of any park's history. The central button represents the timeline view.This lets you view previous trips to the park, and information such as when you rode certain rides. The leftmost button, the calendar, represents the backdating calendar.At the bottom are three buttons floating in a bar - these allow you to control which premium viewing mode you are in. This is the UI for viewing a park's attractions in LogRide on iOS. This does mean I have less time to spend leading implementations of new ideas and features, it does grant me the benefit of "alternative hindsight." Most of the time, I get to witness a final implementation before I even write the first line of code. The nature of the LogRide project is such that I tend to spend most of my time retroactively implementing features the iOS team implemented previously. I did this using the traditional method of rough scratches on notebooks until I was satisfied with where I turned out. It's hard to take an effective first step on a journey without knowing where you're going. But first, the final product.Īn important part of any project is planning. What follows is the process I underwent to plan and implement such a system. When working on creating the suite of premium features for the Android version of LogRide, I found a perfect use-case for merging some simple trigonometry and Flutter's powerful animation systems to create an intuitive and attractive expansion to our existing navigation.
