The volumetric camera is a simplified term for depth cameras used in volumetric capture rigs. Usually, when we think about such rigs the image of a large DSLR depth cameras studio arises in front of us. However, this is not exactly true if you decide to use a volumetric camera, to be more precise a multiple of them and have your own volumetric studio. In this type of situation you will be looking at a couple of volumetric camera providers and will need software to calibrate them into one rig. <br><br>Website: https://ef-eve.com/

What is the best volumetric camera? Volumetric camera is a simplified term for depth cameras used in volumetric capture rigs. Usually when we think about such rigs the image of a large DSLR + depth cameras studio arises in front of us. However, this is not exactly true if you decide to use a volumetric camera, to be more precise a multiple of them and have your own volumetric studio. In this type of situation you will be looking at a couple of volumetric camera providers and will need software to calibrate them into one rig. In my opinion there are two volumetric cameras which can be considered as best for the job: Microsoft Kinect Azure and Intel Realsense D400 series. Microsoft Azure Kinect Volumetric Camera. Both of the cameras in theory display similar specs. However, in reality Azure Kinect proves to be more stable and covers a larger capture area. However, it is more bulky than Intel Realsense. Therefore if you need to record a smaller moving object and have a limited space for the rig Realsense can help. An example could be mounting a camera inside an existing hardware to capture eye movement. However, if you want to capture a full person I would advise to choose Azure Kinect. www.ef-eve.com
Intel Realsense volumetric camera. Azure Kinect currently costs $399 per piece and if you are planning to have a full volumetric setup it is advised to start with 4 of them in the rig. Keep in mind that you can add more of them and have better quality if needed. Usually this is done when you want to have more realistic volumetric video. However, if you will be using your captured data for VFX then 1-4 volumetric cameras might be enough. Intel Realsense cost around $180 which is half of the price of Kinect. Therefore for understandable reasons this might be an option for some project even if the space for the setup is not an issue. Once you have decided on the cameras you can use the SDK it comes with. However, you will need a lot of time for programming and will miss out on many functions if you choose to do so. Therefore, most of the people choose to use volumetric video software. EF EVE™ volumetric capture gives you the ability to automatically sync upto 10 cameras. Which means this will merge all 10 volumetric camera feeds into one moving 3D object. Also the setup can be easily put together and moved whenever needed. www.ef-eve.com
EF EVE™ volumetric capture setup. The software also lets you adjust capture space. If you want to capture a person as realistic as possible, the recommended set up is 2x2 metres. However, if realism is not your goal and if you want to apply VFX you can set your stage as large as the cameras can reach. www.ef-eve.com
Volumetric Video with VFX in Unity. Now you are probably thinking what happens if you want to record realistic video of multiple people. Easy, just record them separately and import them into one scene. The capture would be done by using EF EVE Volcapp software. However, the cherry on top is EF EVE™ Creator software. The tool allows you to take volumetric videos and easily apply meshes, cut it into clips, test preset VFX, post-process it and export. It doesn't matter if you work with Unity, Unreal or other 3D editing software such as Notch or TouchDesigner you will be able to import your recordings. Therefore, your VR, AR, Web project will go smoothly and fast. Creator allows to export obj, ply, abc, gltf and comes with Unity, Unreal, ARcore, ARkit projects for import. www.ef-eve.com
