BIM vs Reality

Using BIM vs Reality

BIM vs Reality is a split-screen comparison mode that syncs your live BIM model with a real capture of the same space — a 360° photo or a Gaussian Splat render — so you can see design and reality side by side. It's launched from a calibrated point cloud in the Capture Hub, and is a different feature from the fixed-camera comparisons in 3D Views and Progress Tracking.

1. Accessing BIM vs Reality

1. Open a Calibrated Point Cloud:

• In the Capture Hub, open the Captures tab and select a point cloud that has been calibrated. The split-view buttons stay disabled until calibration is done. 2. Choose a Split-View Mode:
• From the point cloud's bottom panel, click 360° View or Gaussian Splat to open the corresponding split view.

2. 360° Split View

• The left pane shows the live BIM viewer, locked to the capture's position; the right pane shows the 360° photo taken at that same point.
• Look around in either pane and the other stays in sync — orientation updates both ways.

3. Comparing Multiple Recordings

• Add a second 360° photo from a different capture date at the same location as a third pane, so you can compare two points in time.
• Use Link/Unlink to lock the second recording's orientation to the primary pane, or free it to look around independently.

4. Gaussian Splat Split View

• The left pane shows the live BIM viewer; the right pane shows a free-fly Gaussian Splat render of the same space, mirroring your full camera position and orientation as you move around.

5. Ghosting Elements

• Pick a BIM element to overlay ("ghost") it into the reality pane for a direct visual comparison against what's actually built.
• Right-click to hide ghosted elements you no longer need.

6. Best Practices

• Calibrate Promptly: split view is unavailable until a point cloud is calibrated — do this soon after capture.
• Use Multi-Recording Comparison: compare two dated 360° recordings at the same location to spot changes over time, rather than relying on memory.
