Contents
Block 3D view content depend on the available data of the block. Content display can be controlled from the Display Styles drawer.
Photos
Only photos with known position are displayed in the 3D view.
Photos with complete pose (known position and rotation) are displayed with their oriented view frustum, selecting them allows to display their approximated field of view in 3D.
Photos are colored according to their calibration status and to the RMS of reprojection of their tie points.

Survey points
Survey points symbols allows to identify the survey point type (user tie points or survey points, check point):
Control points are located in the 3D view according to their actual 3D position; user tie points are located on their estimated 3D position.
Survey points are colored according to the RMS of reprojection error of their measurements in input photos:
(*) Not enough measurements
You can control camera size from the Display Styles drawer.
Generated Tie points
Colored tie points generated by aerotriangulation.
You can control point size from the Display Styles drawer.
Splats
Splats are an alternative representation of the tiepoints that adds textured surfaces to each point to provide a better understanding of the 3D context (represented scene). Each tie point is depicted as a flat square covered by part of a photo seeing the point.
Splats are processed by default during the aerotriangulation step. However, processing also can be started manually from the block general tab.
Show and hide splats from the Layers menu, and control splats size using the dedicated slider.
Please note that splats do not reflect the quality of the Reality Mesh and are meant only to help understanding tie points positioning.
You can control splats size from the Display Styles drawer.
Point clouds
Block's point clouds imported from scans.
You can control point size from the Display Styles drawer.
3D Mesh
Allows to display a 3D mesh produced from this block.
Display Styles:
- Source: select which mesh to display among supported block productions (supported formats: 3MX, 3SM).
- Style: select a predefined style to set wireframe and texture combination.
- Backface culling: hides sides of the model facing away from the camera, it may be used to ease navigation in interior scenes.
Annotations
Annotations are a specific production type extracting automatically information from reality data using ContextInsights AI technology.
Several types of annotations exist but all of them cannot be viewed in 3D:
are the annotation-types viewable in the 3D-view.
In 3D-View, Annotations can be shown, hidden or filtered by class using the display style tab. It is also possible to overlay3D-objects annotations onto a mesh that would be part of the same reconstruction.
