DEPTH & 3D DEPTH CONTROLS
Read the scene as distance, live and in 3D
LIVE 2D DEPTH
In the DEPTH view, controls appear at the bottom center of the frame. Depth is rendered straight from the sensor, color always represents distance, never the camera image.
| Control | Function |
|---|---|
| RANGE slider | Maps scene depth to the display. Center (50) auto-fits the full scene, near and far. Left emphasizes close objects; right emphasizes far objects. |
| GAIN control | Adjusts the brightness intensity of the 2D grayscale/mono depth map. Also applies to the live 3D point cloud and the gallery 3D scan viewer, bringing out subtle depth structures. |
| DEPTH COLOR ON/OFF | ON = false-color by distance (red through blue). OFF = mono grey by distance. |
LIVE 3D DEPTH (DEPTH_3D)
The DEPTH_3D view renders the depth sensor as an orbitable point cloud. The control bar sits over the 3D canvas.
| Control | Function |
|---|---|
| RANGE | Same as 2D, affects both mono and false-color in 3D. |
| GAIN | Adjusts the brightness / intensity scale of the point cloud points in mono/grayscale. Applies to both live point clouds and the gallery 3D scan viewer. |
| DEPTH COLOR ON/OFF | False-color vs mono grey point cloud. |
| ↻ RESET | Return to the saved default camera angle (or auto-fit if none saved). |
| ⊡ SAVE VIEW | Store the current orbit as the startup default for 3D depth. |
Navigation
- Drag, rotate
- Scroll, zoom
- Right-click drag, pan
The stats line (points, heatmap) and hint text are hidden in DEPTH_3D for a clean field view. POINT_CLOUD and ROOM_MAP still show stats.
HOW THE DEPTH RANGE BEHAVES
- SPECTER automatically finds the nearest and farthest valid depth in the scene each frame, then smooths that range so the image does not flicker.
- RANGE at center is the recommended default for seeing everything at once.
- In false-color mode, the full palette spreads across that range, so close objects and far walls can both be visible when RANGE is centered.
- This is not the same as POINT_CLOUD mode, which textures its points from the live camera. In DEPTH and DEPTH_3D, color means distance only.
Seeing flicker on an older build? Update to the latest build (range smoothing fix) and keep RANGE near center.
LIVE DEPTH TUNING
Fine-tune your depth sensor's capture quality in real time under Settings > Cameras > DEPTH TUNING. These adjustments apply live to your active feeds without requiring a restart:
- Hole-fill: Fills empty or black pixels in the depth map (caused by light-absorbing or reflective surfaces) by interpolating data from neighboring depth points.
- Visual preset: Cycle through built-in sensor profiles (such as short range, high accuracy, or high fill-rate) optimized for different venue shapes.
- Temporal persistence: A temporal filter that averages depth frames over time to eliminate rapid pixel flickering and stabilize structural shapes.
- Spatial smoothing: An edge-preserving filter that smooths out jagged contours and suppresses high-frequency sensor noise across flat planes.
- Max range: Sets a hard cut-off boundary (in meters) for depth calculations, ignoring background noise and far-off movement outside your immediate investigation site.
SAVED VIEWPOINT
Use ⊡ SAVE VIEW to store your preferred 3D camera angle. SPECTER restores it on the next launch, so you walk into a venue with the depth view already framed. ↻ RESET returns to that saved angle at any time.
