Like it or not, both 3D and Virtual Reality are here to stay. Tech ranging drastically in size and focus are embracing the next generation of immersive experience products such as Oculus VR (acquired by Facebook in March of 2014), Jaunt VR, Google Project Tango, and Matterport.

Whereas Oculus and Jaunt seem to be concerned with solely the capture and displaying of immersive 360-degree footage however, Google and Matterport’s technology focuses less on what light hits its lens, and more on the loads of spatial data their products’ sensors gather. Both Google and Matterport are working to automate the tedious task of digitizing our physical word.

Matterport’s software and hardware development team together since 2011 now has a fully functional camera for sale that uses an iPad-only application for controlling. The form of the Matterport is bulky and awkward, but it shouldn’t be compared to a typical DSLR camera. Instead of just one lens protruding from a sensor within a body, the Matterport has 15 (based on images) parts that are required to be facing the camera’s environment to work. Additionally, there is significantly more on-board data processing that has to go on within the Matterport than on a typical camera so naturally, it will take up more space. Matterport’s frontier technology isn’t cheap either. The camera is $4500 and there are other monthly fees involved for cloud-based data storage and processing.
To generate a 3D .obj file from the physical space around it, the Matterport gets set in a position in a room, and instructed to begin a scan via the connected iPad. The camera then makes a 360-degree spin on its tripod in about a minute then will start processing what it saw in the cloud. Once the data handling from the scan is complete, the iPad will display which parts of the environment were well captured and which were not (due to obstructions such as furniture or distance from the camera) letting the user know where to place the camera for the next scan. Depending on the complexity, size and number of obstructions within the area being modeled, the number of scans required to be done will vary.
While Matterport’s system has produced some impressive sample results as seen on their website they’re up against the big guns: Google is too exploring this type of digital mapping. Matterport’s behemoth Mountain View counterpart is thinking much smaller though. Declassified in February of 2014, Google showed off that it has been working on a similar concept to Matterport, but ported to a mobile device and coined ‘Project Tango.’ Currently distributing their first few hundred prototype Android devices to developers and researchers around the world, Project Tango does seem significantly more promising than Matterport. Even though Matterport’s gear is readily available whereas Google’s is still in the prototyping phase, it’s certainly evident that the future of just about all tech is mobile. Thus Tango is a handheld device unlike the tripod-bound Matterport.

Due to Tango’s clear mobility, X, Y, and Z-axis information dealing with position and rotation has to be gathered. When mapping, Google says its device is capturing over 250,000 points of data per second from the devices three cameras and multiple interior sensors. Even though the current Project Tango’s has its “rough edges,” Google is likely making the product on a small device so once those rough edges are smoothed over, any Android device with the right sensors inside can run Tango software.

Given the rate at which devices are shrinking and how mobile is starting to dominate all of tech, it would seem as though Project Tango is on the better track. Even though they don’t yet have much to show for with their efforts, Google’s focus on something handheld from a user standpoint makes all the sense in the world. Regardless of how digital mapping of 3D environments gets done, its potential use in art, history, real estate, social media, gaming and a plethora of other areas is not going anywhere.
