How to capture a venue in 3DGS with rented XGRIDS gear.

This is an illustrative field note, not a client case study. It uses no client names, dates, or results — only a realistic picture of how the workflow tends to run. Volumet rents the equipment; the scene is produced by the renter or their partner.

When your venue needs to be seen, not measured

Say you want a photorealistic, explorable model of a venue — something a client can walk through in a browser to plan a production, not a survey-grade point cloud. The priority is visual fidelity and atmosphere: lighting, materials, and the feel of the space.

That is exactly where 3D Gaussian Splatting fits. Rather than a clean geometric mesh, 3DGS reconstructs a soft, lifelike scene from captured views — ideal for venues, sets, and spaces where the experience matters more than millimetre accuracy.

Photoreal where mesh falls short

Traditional meshes struggle with reflective, transparent, and fine-detailed surfaces — stage lighting, glass, foliage, fabric. 3DGS handles these gracefully, producing scenes that look convincing from any angle and load smoothly in a browser or XR headset. For a venue, that means a walkthrough a client can actually explore, not a technical deliverable that needs interpreting.

• Photorealistic, explorable scenes
• Handles reflective and complex surfaces well
• Browser and XR-friendly delivery
• Great for venues, sets, and marketing

From walkthrough to scene

The capture itself is a four-step rhythm, and none of it depends on Volumet beyond the rental and optional onboarding:

• Plan. Identify hero viewpoints and the path a viewer should take; plan even coverage and consistent lighting.
• Capture. Walk the venue with rented XGRIDS equipment — PortalCam for dedicated 3DGS, or a K2 capture feeding the pipeline.
• Process. Reconstruct the 3DGS scene through the XGRIDS / LCC CyberColor workflow.
• Deliver. Publish a browser-viewable scene or export for XR and virtual production.

What your venue scene delivers

Typical outputs from a 3DGS venue capture you run, subject to device, software, and processing workflow:

• 3DGS scene — a photorealistic Gaussian Splatting scene, explorable in a browser or XR.
• Point cloud — an underlying point cloud where spatial reference or measurement is also needed.
• Digital twin seed — a visual foundation for digital twin and previsualisation experiments.
