Usually, when I start prototyping some ideas, I create a custom Editor’s tool to visualize the main spatial computing algorithms I plan to use.
It helps with a few things: — Visually explain specific details of an interaction’s behavior to other people. 3D math is quite challenging to communicate quickly, just using words or static images. — Get insights and a comprehensive understanding of spatial properties and their relationships to leverage them thoughtfully in the design of API and UI.
In this shared example, I projected the index pinch movement on a plane facing a user. I displayed all the calculations and properties needed to build a UI interaction. For example, Angle for circular menus/pickers (https://x.com/Volorf/status/1777268616708133297) and XYZ offsets for 1D/2D/3D sliders/selectors (https://x.com/Volorf/status/1764565204350775468).
I used the Handles class to create the 3D math visualizer, which helps extend Unity’s Editor functionality with custom behavior. I did it with the Gizmos in the past, but they are less customizable than Handles.
Hope that future design tools will have such visualizations built-in since they’re extremely helpful for developing an intuition of how spatial algorithms work and what they are capable of.
