The 3D Data Viewer provides a unified environment to visualize and validate all representations of your 3D data. It supports point clouds, meshes, photospheres, and any additional formats included in your Data Bundle.
This viewer is used across the Prevu3D ecosystem to inspect data quality, explore capture coverage, and understand the spatial context of your scene directly in the browser.
Overview
The viewer is designed to display the multiple visual formats that can exist inside a Data Bundle. You can seamlessly switch between views to analyze your data from different perspectives.
Supported formats include:
Point clouds
RealityMeshes
Photospheres
Future formats added through the platform’s evolving capabilities
This provides a consistent and comprehensive viewing experience regardless of how your data was captured or processed.
Opening the 3D Data Viewer
You can open the 3D Data Viewer directly from the RealityPlatform.
There are two ways to access it:
Double click a Data Bundle to open it in the viewer.
Right click a Data Bundle and select “View Dataset”.
The viewer will load all available representations in the bundle, and you can begin navigating or validating your data immediately.

Navigation Modes
360 Degree Picture Navigation
If photospheres are available, you can enter the 360 degree picture view to navigate capture positions and inspect visual details.
You can:
Click a photosphere to enter it
Transition between photospheres by selecting them in the 3D scene
Review lighting, texture quality, and station placement
Perspective Navigation Mode
You can switch to a free navigation mode to explore point clouds, meshes, or other 3D representations.
This mode allows you to:
Fly through the environment
Inspect density, surface fidelity, and alignment
Validate completeness and data quality
Navigation Controls
The navigation controls are the same as RealityTwin workspace. See the details over here.
Reset Viewpoint
Select the Home icon to return to the default camera position.
Switching Between Representations
The viewer allows you to switch between different representations of the same dataset. You can view:
Point cloud
Mesh
Photospheres
Any other supported formats in the Data Bundle
Switching views is immediate and keeps your orientation in the scene, allowing smooth comparison. You can also enable multiple visual representation at the same time.
Example with both “Pointcloud” and “Mesh” representation at the same time.

Measurement Tools
The 3D Data Viewer includes the same measurement capabilities available in RealityTwin, allowing you to take quick and accurate measurements directly inside your 3D data.
You can access the measurement tools from the viewer toolbar. These include:
Simple distance measurement
Area measurement
Coordinate inspection
Diameter measurement
Orthogonal measurement

All measurement actions work the same way as in RealityTwin. For detailed instructions on how to use each tool, see the Measurement Tools in RealityTwin article.
Important notes
Diameter measurement is only available when viewing a Mesh representation. The tool requires mesh geometry to detect cylindrical surfaces.
Measurements created in the viewer are temporary by default. They are visible only to you and will not be saved.
Powered by the Data Bundle
The 3D Data Viewer loads content using the Data Bundle, a unified container that stores:
Raw inputs such as E57, LAS, images, and videos
Optimized outputs such as point cloud tilesets, meshes, and photospheres
Additional and future ready representations
Because all these formats share the same structure and metadata, the viewer ensures:
Consistent visualization across all formats
Accurate alignment between point cloud, mesh, and images
