Understanding Volumetric Capture Technology

The groundbreaking nature of volumetric capture becomes clear when you understand what makes this technology special. This revolutionary approach to filmmaking creates an experience that changes how audiences connect with filmed content in ways never seen before.

What is volumetric video?

Volumetric video captures three-dimensional space, including people, objects, and entire environments through advanced 3D scanning techniques. The technology records subjects in 3D and creates digital models that viewers can see from any angle at any time. Multiple cameras with depth sensors work together to capture three-dimensional scans. This results in a complete digital recreation that viewers can explore with six degrees of freedom.

The system works by placing many synchronized cameras around a subject or scene. These cameras capture data from multiple angles at the same time. The data then transforms into a sequence of 3D models. The system creates meshes and textures after the capture. Everything compresses into a data file ready for interactive viewing and real-time rendering.

Volumetric video stands out because it’s neither traditional video nor computer animation. This hybrid preserves authentic performances while allowing digital manipulation, making it ideal for creating character assets and digital beings.

How volumetric capture is different from traditional filming

Traditional filming relies on a principal camera to capture scenes from fixed points of view. Volumetric capture uses multiple witness cameras for complete 3D reconstruction. Traditional video offers passive viewing while volumetric content demands active participation, enabling interactive VR/AR experiences.

Key differences include:

  • Dimensional freedom: Traditional video stays flat (2D), but volumetric captures full spatial dimensions of a scene

  • Viewer agency: Directors control what you see in traditional media, but volumetric content lets viewers move freely around the scene

  • Post-production flexibility: Editors can work with volumetric captures from any angle without new shoots

  • Integration potential: These 3D assets blend into virtual environments, unlike traditional video footage

Volumetric video also stands apart from other immersive formats. While 360-degree video lets you look in all directions, it lacks depth—like watching from inside a snow globe. Volumetric video creates genuine three-dimensional space to explore, allowing for the creation of 360-degree 3D holograms.

This technology also differs from motion capture (mocap). Mocap requires actors to wear tracking suits with markers to record movement data for digital characters. Volumetric capture needs no special suits or markers and preserves the performers’ authentic appearance, making it ideal for creating realistic character assets.

Benefits for independent filmmakers

Volumetric capture gives independent filmmakers access to tools once limited to big-budget productions. Directors can adjust camera angles and points of view after completing the shoot. Actors can focus on delivering uninterrupted takes without worrying about camera setups, enhancing the overall filmmaking process.

Depthkit software has created a radical alteration by offering a flexible option for creators without expensive capture stages. Anyone with video or film experience can adapt their skills to volumetric experiences. The software shows live previews to adjust lighting and camera angles instantly, which makes production much smoother and enables real-time recording of spatial content.

Intel RealSense and other affordable depth cameras have made professional volumetric capability available to more creators. A simple volumetric kit with a Kinect depth camera, optional digital camera, and laptop fits in a backpack instead of needing complex studio setups, providing a portable capture solution for on-location shoots.

This technology gives independent creators the ability to tell unique stories that were impossible before. They can now create narratives from real places and people in interactive environments where viewers become active participants, revolutionizing the filmmaking community’s approach to storytelling.

Essential Equipment for Budget-Friendly Volumetric Capture

You need to think over your component choices carefully to build an affordable volumetric capture setup that balances quality and cost. Let’s get into the equipment you’ll need to create professional-looking volumetric content without spending too much.

Depth sensors: Kinect, Intel RealSense, and alternatives

Your budget-friendly volumetric capture system’s foundation starts with the depth sensor. The Microsoft Azure Kinect DK stands out as a prominent choice that gives you high-resolution depth capture (512 x 424 pixels), quality 1080p video, and lets you manually control white balance and exposure. Microsoft stopped production, but the hardware lives on through the Orbbec Femto Bolt/Mega, which uses a similar depth sensor hardware.

The Intel RealSense D455 is another great option for RGBD capture. It combines RGB cameras with structured light technology to capture depth accurately to the millimeter. You’ll get depth resolution up to 1280 x 720 pixels and RGB resolution up to 1920 x 1080 pixels at 90 frames per second, making it suitable for real-time recording of volumetric video.

The Microsoft Kinect V2 (Xbox One Kinect + Windows adapter) still works well if you’re looking to spend less, though you’ll need to install the Kinect For Windows SDK. The Orbbec Astra works well too as a budget option if you’re just starting out with depth filming.

Camera options: DSLR vs. mirrorless for texture capture

Better color information comes from pairing depth sensors with dedicated cameras. DSLRs give you great image quality and reliability but they’re bigger. The Canon EOS 90D works great with its excellent autofocus and 4K video capabilities for volumetric work.

Mirrorless cameras often give you better video performance in smaller bodies, even though they’re not DSLRs. Sony’s Alpha 9 III shines with its global shutter and high frame rates (up to 120fps RAW) – perfect for 4D volumetric capture. The Panasonic Lumix GH5 gives you great value despite being mirrorless.

Fixed focal length (prime) lenses are worth looking at for their sharpness and speed. To name just one example, see the Sony 50mm G Master lenses that give you the precision needed for accurate texture and detail capture in 3D modeling.

Computer hardware requirements

Your computer needs serious power to process volumetric data and handle real-time rendering. Here’s what your system should have at minimum:

  • CPU: Intel i7 7700K or better

  • RAM: 16GB (8GB minimum for simpler setups)

  • GPU: NVIDIA GeForce 960 or better, with NVidia GPUs working best for compatibility

  • Storage: Fast write speeds (7200rpm or SSD) are vital for recording multiple streams at once

  • Network: 1Gbps connectivity handles real-time streaming from multiple sensors

Lighting considerations for optimal results

Good lighting makes a huge difference in volumetric captures. You’ll need consistent, even illumination to reconstruct 3D data accurately, unlike traditional video.

Diffused lighting works better than hard sources that can wash out details or create harsh shadows. LED panels from Elgato (up to 2,800 lumens with adjustable color temperature) are a great way to get controllable lighting without spending too much.

Put your lights in positions that minimize shadows while keeping the subject separate from the background. A three-point lighting setup with key, fill, and back lights at different intensities creates depth without problematic shadows.

Complex productions benefit from synchronized lighting with your camera system to ensure frame-accurate data during long recordings. Tools like Ambient Recording’s ACN-CL Lockit provide universal external sync signals to your entire setup, enhancing depth control in your captures.

Setting Up Your DIY Volumetric Studio

A functional volumetric studio needs careful planning and precision to set up. You can achieve professional results without spending too much money. All you need is a few square meters and some technical expertise to create a versatile volumetric capture studio.

Space requirements and preparation

Your recording capabilities depend on the capture space size. Professional volumetric studios range from expansive 8m × 8m rooms to compact 3m × 3m setups. A modest 3m × 3m space works well for independent filmmakers and provides enough room to capture full-body shots.

Your space must have:

  • Clean, uncluttered floors and walls

  • Sufficient ceiling height (minimum 2.5m for full-body captures)

  • Access to multiple power outlets for sensors and lighting

  • Minimal external noise and vibration

The floor acts as your coordinate system anchor, so proper preparation matters. A level, non-reflective surface works best for accurate depth sensing and calibration.

Camera and sensor positioning

The sensors should face inward toward the subject from the perimeter of the capture area. This setup creates a 360° overlapping point cloud that you need for complete reconstruction.

Best results come when you:

  • Mount sensors vertically (90° clockwise, connections facing down) to maximize field of view

  • Place sensors 1.1-1.5 meters from the ground

  • Keep sensors 1.75-2.5 meters from the capture area center

  • Space sensors evenly for complete coverage

Beginners can start with three sensors—one “hero” sensor at eye level facing the subject directly, plus two more at slight angles. You can add more sensors up to five or beyond as needed for full 360-degree 3D hologram capture.

Background and lighting setup

Budget-friendly setups work well with plain, evenly-lit walls, unlike high-end studios with permanent green backgrounds. The lighting must be consistent and uniform without affecting depth sensing.

Your volumetric lighting should:

  • Use diffused lighting instead of harsh, direct sources

  • Minimize shadows on your subject with proper light placement

  • Add haze machines if you want atmospheric effects

  • Use barn doors or flags to control light beams

ARRI 1K or 2K fresnels create defined light beams that make volumetric effects stand out with their strong, narrow-beam output, enhancing the overall quality of your immersive video captures.

Calibration process

Multiple sensors need alignment into one coordinate system through calibration. Here’s what you need to do:

  1. Place a calibration structure in your capture space’s center

  2. Make sure all sensors can see the structure

  3. Take depth snapshots from each sensor

  4. Process captures to estimate pose parameters

  5. Add calibration data to your volumetric capture software

The live point-cloud streams should properly show the calibration structure’s shape. This verification step ensures your captures will align correctly in post-production, crucial for creating seamless interactive 3D content.

Volumetric Video Capture Software Options

Software selection is a vital step to create your budget-friendly volumetric video system. The software you pick will determine your captures’ quality and workflow flexibility after assembling the hardware.

Depthkit and its workflow

Depthkit leads the market as the most accessible volumetric video software. Users have published volumetric experiences in industries of all types. This software works with consumer-grade depth sensors and creates lightweight, high-performance files that integrate smoothly with Unity game engine or other 3D content creation tools.

Depthkit’s workflow resembles traditional video production but produces three-dimensional output. You start by capturing depth and color data on set with live preview features. The next step involves editing and refining footage through Depthkit’s depth data refinement algorithms. Your final step exports captures to your chosen 3D destination, ready for use in virtual production pipelines.

Depthkit’s product tiers include:

  • Depthkit Core: Single-sensor capture with Azure Kinect, Kinect v2, or RealSense

  • Depthkit Cinema: Pairs professional cameras with depth sensors for up to 8K resolution

  • Depthkit Studio: Connects up to 10 Azure Kinect sensors for full 360-degree captures

Open-source alternatives

Budget-conscious filmmakers can turn to LiveScan3D and VolumetricCapture as leading open-source options. LiveScan3D produces quality footage that meets expectations and stands out as the only fully open-source option available to researchers and experimenters.

VolumetricCapture provides a research-oriented yet optimized toolset for multi-RGB-D sensor recording. This system arranges “Eyes” (headless applications) to manage individual sensors through a centralized UI application called “VolCap”. Users can mix and match Intel RealSense D415 and Azure Kinect DK sensors for versatile depth filming setups.

BuildingVolumes deserves mention as a revolutionary force. This global team of creatives and software engineers wants to build a completely free and open-source volumetric capture pipeline, potentially transforming how the filmmaking community approaches volumetric projects.

Subscriptions vs one-time purchase solutions

Software companies now prefer subscription models, which affects volumetric capture solutions. Depthkit Studio costs $3,000 per month as a paid subscription that includes unlimited capture and live streaming features. Academic and non-profit organizations can request special pricing.

Subscription models reduce upfront costs but often cost more long-term. The subscription cost becomes higher than a perpetual license after about two years of use with some software. Monthly subscriptions are a great way to get instant updates, avoid large initial investments, and plan budgets with predictable expenses.

Depthkit Studio gives novice users the best experience when high-quality results matter. LiveScan3D and VolumetricCapture need more technical expertise but offer flexibility for experimental volumetric projects.

Post-Production Workflow for Volumetric Content

The real magic happens in post-production after you capture volumetric data. This phase turns raw captures into polished, usable 3D content through several steps, including the creation of interactive VR/AR experiences.

Cleaning and processing captured data

Raw volumetric data needs major cleanup to remove noise and artifacts. Professional software like HoloEdit segments materials by identifying surface points by type and estimates material properties. You can edit scanned data meaningfully without relying on basic 2D filters or keying approaches.

Depthkit’s budget-friendly refinement algorithms let you review footage and improve data quality instantly. You can clean up specific 3D regions or remove elements based on color range. Some systems use machine learning for “super normals” that provide more realistic surface normal relighting, enhancing the overall quality of character assets.

Texture mapping techniques

Texture mapping connects visual information to your 3D models. Visual properties build up along viewing rays to create the final image. You’ll usually pick between:

  • Point-based mapping – Gives higher spatial resolution with points carrying attributes like color and size

  • Mesh-based approaches – Makes traditional triangle meshes with lower data volume but limited resolution

Texture mapping displays highly detailed volumetric mesostructure surfaces at lower performance cost. This lets you abstract detail from the animating surface and use quick animation methods without extra costs, crucial for creating efficient interactive 3D content.

Exporting for different platforms

Once you refine your capture, you’ll export it properly. Depthkit gives you multiple export formats:

Combined Per-Pixel exports blend depth and color data into single files optimized for Unity game engine. WebXR projects work best with Draco-compressed geometry files and video textures at controlled bitrates. Tools like 4Dfx help you adapt content for WebXR, VFX, and XR pipelines with compression rates up to 1 MB/s, enabling efficient livestreaming of volumetric video.

File size management matters – pick the right compression settings for your target platform. Mobile VR projects should keep texture resolutions at 2048×2048 for universal support. Consider using the Vimeo Depth Player or Depthkit.js Web Player for easy online distribution of your volumetric content.

Troubleshooting common issues

Post-production comes with several common challenges. Transparent or reflective surfaces often create data gaps that need extra cleanup. Camera color consistency requires careful calibration and post-processing.

“Depth banding” on mobile platforms might need camera clip plane adjustments. Most volumetric software includes special tools to fix these issues, with painterly tools that keep projected texture consistency across segment boundaries. These tools are essential for creating seamless and immersive augmented reality experiences.
