Display and navigation options



Max points to load to GPU (millions)

This option is used to set a maximum number of point to be rendered in the 3D scene. The limit is cumulative for all the loaded point clouds. It depends on the characteristics of the graphics card.


Limit points for Orthophoto to ... (millions)

Check this option and set a value to limit the maximum number of points (belonging to the flagged and loaded point clouds) used snapping an orthophoto (or Virtual Scan). It depends on the characteristics of the graphics card. This limit is not concerning the X-ray orthophotos and Blueprints.


Movement speed

This option sets the translation speed when panning in pivot mode. It is an adaptive parameter, for the most part the default value (1) should be fine.


Slice views thickness

This option sets depth of a single slice when using the Slice view or the Horizontal section view.


Set  background gradient

Change the uppermost and lowermost color of the background of the 3D rendering window.


Object reference frame size

All models and cameras can draw their local coordinate frame by enabling the property. Here the frame size (in meters) is specified to improve its visibility accordingly to the extent of the scene.


Pivot mode controls

Here you can select two options: “Reconstructor” and “Move with 3-button mouse”. These options are two sets of controls for the Pivot Mode. The second one is the default and is described here.

If you  select “Reconstructor”, then in pivot mode the following controls apply:

  • Rotate: To rotate the model around the pre-defined center of rotation (pivot), move the mouse within the 3D window while keeping the left button pressed.
  • Pan:  To pan the model in X and Y, move within the 3D window while keeping the left button and the Shift key pressed.
  • Zoom: To translate the model along the Z-axis, move the mouse within the 3D window while keeping the left button and the [Ctrl] key pressed or use [Ctrl + mouse wheel] to zoom in and out along the Z-axis. In the latter case, if the mouse pointer hovers a valid 3D point, the zoom converges to that point.
  • Change pivot: double-click the left mouse button plus [Ctrl+Shift ] on a valid 3D point.


Bounding box colored with colorID

When this option is checked, the bounding boxes of the project items are colored based on the item's colorID. If this option is unchecked, the bounding boxes are colored with the default (yellow) color.


Bounding box edges smoothing

Apply an anti-aliasing algorithm to bounding box edges. It is suggested to leave this option checked unless the graphic card does not support lines smoothing.


Enable human movements while rotating

When this options is checked, a small human avatar appears in the bottom-left corner of the 3D rendering window. While you navigate in the 3D scene, you will experience that after doing many rotations, your viewing direction will still be oriented according to the vertical axis and to the horizontal plane defined by the current UCS. This is like a human being that, after rotating his head around his neck in many directions, when relaxing the head will go back into the natural position, which is in line with the spinal chord.

When this option is unchecked, while navigating the 3D scene you will experience that after some rotations the reference to the UCS's horizontal plane is lost, and that you are floating in the space like an astronaut floats among meteors, without gravity force.


Draw Annotations to 3D scene sides

Annotations will be arranged on the sides of the render window, at the exact insertion point.


Render models' normals

View vectors that describe the normals directions for point clouds and meshes, if they have been computed.


Blend models' Color ID on their current color

Blends the color layer (reflectance, confidence...) whit the Color ID. This two features are available in the Property Window.
