How to use 3D visualization with 3D data for golf
Onform's new 3D visualization is now available to all coaching users in 'beta testing' mode. During this time, the feature is available to anyone with an Onform 'Coach' account. The 3D skeleton is computed entirely on the device itself. As such, a newer iPad or iPhone (currently only supported on iOS devices) will be required. Your device must be running iOS version 17.x or newer. Any iPhone 12 or newer or any iPad or iPad Pro with an A15 bionic chip or newer will suffice. Currently, Onform's 3D visualization capability is available only for full golf swings. Many more sports will be added in the future.
Getting Started
You'll need to use the Auto-Detect recording mode (shown below) within Onform to capture a golf swing from the face-on or down-the-line angle. Simply position the golfer in view and have them take a full swing.
Once captured using Auto-Detect, the 3D visualization will be computed automatically and played back in slow motion. You can use your finger to drag the 3D skeleton and rotate it to any angle.
Additional visualizations include Hand Path, Slide and Sway tracking and many more coming soon. To access these visualizations, tap the 'magic AI' button and select which visuals you'd like to show as shown below.
3D can be combined with our multi-cam recording capability as well. Simply add other devices by choosing the 'auxiliary' camera mode within the additional device, which will pair to the primary device recording the auto-detect full swing.
3D FAQ's
How do I get 3D to work?
Record a golf swing using the Auto-detect recording mode within Onform and 3D will automatically be computed. We recommend using an iPhone 14 or newer or a 2020 iPad or newer for best results.
Where is the data for the swing?
At this time (Feb, 2025) we are not providing data with the visualization pending ongoing accuracy testing. We will eventually publish key data when it becomes available, along with our accuracy testing measurements.
Do I have to be connected to internet?
No. We don't require the internet when computing the 3D model, so you are free to use it completely offline.
Can I capture from any angle?
We designed the feature to be used when recording from face-on or down-the-line, so we recommend capturing from those angles.
Does the iPhone or iPad have to be on a tripod to work properly?
No, you can simply hold the device and capture like a normal video. Of course it helps to be still, but you don't have to be 'tripod still'.
What can I do with the 3D information?
The visualization is a great help to better understanding the mechanics of a golf swing. For instance, enabling the hand-path visualization helps a student to better see their clubpath, and help diagnose reasons for slices and hooks. You can also use it to see setup stance, takeaway and other key aspects of the swing. With the forthcoming data, you'll be able to compare objective information before and after making swing changes.
Can I use 3D with multiple cameras?
Yes! You can easily use our multi-cam featueres with 3D. At this time, simply set your primary camera to 'Auto-detect' and the other cameras to 'Auxilliary'. You'll get amazing multi-angle recordings with 3D! Below is an example of using 3 cameras (2 iPhones and 1 iPad in this case) to capture face-on, down-the-line and impact, along with the 3D view. You can adjust the view panes with the 'layout' button in the lower right corner as seen below.
