Welcome to the ARVRinEDU Advent Calendar 2022! Our special focus this year is on STEAM (science, technology, engineering, art, and math). These mini blogs will spotlight an immersive resource that can be easily implemented into the curriculum.
Record3D (TECHNOLOGY, AR)
One of my favorite technologies available on our mobile devices is LiDAR technology. LiDAR uses the device camera for depth sensing. LiDAR stands for light detection and ranging, basically sending out lasers to map out a 3D object with texture. The 3D scan can be a single object like furniture or a person, an entire classroom, or the school playground. There is no metaverse without 3D objects, so our students must be equipped with the skills to create their own 3D content.
Most LiDAR apps capture static 3D objects, but I’ve come across another resource that captures a short 3D video. My dog was captured near our fireplace, and you'll notice I viewed her from one angle rather than scanning her from all angles. Therefore, viewing her 3D video looks better from some angles and misses a lot of details when viewed from other angles. After creating the 3D video, the experience can be rotated to view on the device or placed on the ground using augmented reality. The option to export your 3D video is available through a Sketchfab integration; however, the 3D video files tend to be extremely large and not easily uploaded to other platforms, so short videos are best.
The technology will continue to change, but the important part of using 3D video content is allowing our students to be content creators rather than passive consumers.
Steps to get started
Download the Record3d (iOS only) app here. LiDAR apps work on the iPhone Pro or the iPad Pro.
Open the app and select the record button at the bottom.
Capture a scene for a few seconds.
View the experience in augmented reality by selecting the AR icon on the right side.
Capture a video of your 3D experience from the button on the button right. Enjoy!
