Navigation Modes

 
Information: This option is also available in the Volumes view: On the Menu bar, click View > Volumes and then click Volumes.

Allows the user to change the way to navigate in the 3D View, which defines how the 3D view reacts when using the mouse or keyboard:

  • Standard: Pix4D standard navigation mode.
  • Trackball: The camera movements are defined relatively to a ball placed at the center of the view.  Recommended to efficiently navigate around a single centered object.
  • First Person: Allows the user to interact with the view by simulating piloting the camera rather than manipulating the model. Recommended for close inspection and complex models requiring more degrees of freedom.

For more information and a full description of all the possible actions to navigate in the 3D View using the mouse or keyboard: 205360675.


Perspective/Orthographic

 
Information: This option is also available in the Volumes view: On the Menu bar, click View > Volumes and then click Volumes.

Defines the projection used to display the layers in the 3D View. By default, the perspective projection is used. It is possible to switch between perspective and orthographic projection by clicking on the Perspective/Orthographic option of the rayCloud Menu bar or the Volumes Menu bar.

It is also possible to change the view type from perspective to orthographic using the keyboard by pressing "5".

  • Perspective projection: Parallel lines don't look parallel and further objects appear smaller. This is what human eyes see.
  • Orthographic projection: Parallel lines stay parallel. Therefore the size of objects does not depend on the distance. This view mode is recommended for technical drawing.

Information: This option is also available in the Volumes view: On the Menu bar, click View > Volumes and then click Volumes.

Allows the user to change the color of the background in the 3D View.

The Select Color pop up appears:

The Select Color pop-up has the following sections:

  • Basic colors: Selects a basic color.
  • Palette: Selects / modifies a color using the palette.
  • Color Properties Values: Modifies a color typing the color properties values (Hue, Sat, Val, Red, Green, Blue).
  • Display of the selected color.
  • Add to custom colors: Adds the selected color to custom colors, available for other projects.

And the action buttons:

  • OK: Confirms the changes.
  • Cancel: Does not save the changes.

 

Display Sky

 
Information: This option is also available in the Volumes view: On the Menu bar, click View > Volumes and then click Volumes.

Allows the user to display a realistic sky gradient in the horizon of the plane where the project is based.

New Processing Area

A Processing Area is an area that restricts the model displayed and/or the outputs generated. Only one Processing Area can be drawn/imported in the project. If a Processing Area already exists, the option New Processing Area is grayed out. 

For more information about the Processing Area: 202558439.

For step by step instructions on how to draw a Processing Area: 202560179.

Once a new Processing Area is created, the right sidebar displays the following information: 202558449.

New Scale Constraint

A Scale Constraint is a an line with known real Cartesian distance between 2 points, allowing to set up a local scale of the model.

It is a mathematical constraint over the geometry of the project.

It is used when:

  • No GCPs are not being used.
  • No good image geolocation is used for the images.

It is used to improve the relative accuracy by adding a local scale to the project, by defining the real distance between 2 known points.

 
Important: 
  • It is recommended to use the several Scale Constraint and distribute them along the project.
  • Once the Scale Constraints objects are added, it is needed to repotimize.
 
Warning: When creating Scale Constraints, if the project does not have image geolocation, it is suggested as well to create Orientation Constraints to set up an local orientation for the model.
 
Example: In the real model, a Cartesian distance between point 1 and point 2 is known to be 5 meters, then, it is possible to create a scale constraint (line) having as vertices the Points A and B and setting up the distance between the points to 5 meters.

Once a new Scale Constraint is created, the right sidebar displays the following information: 202558219.

 

New Orientation Constraint

A Orientation Constraint is a line that represents a known axis, allowing to set up an local orientation of the model.

It is a mathematical constraint over the geometry of the project.

It is used when:

  • No GCPs are not being used.
  • No good image geolocation is used for the images.

It is used to avoid a rotated model or to force a certain orientation to the model, by defining one or more desired axes (X and /or Y and / or Z).

 
Important: 
  • In case of using several Orientation Constraint, if they represent a different axis (X, Y, Z), they must be placed with 90º between each other to avoid a deformed model.
  • It is possible to create more than one Orientation Constraint for one axis (for example, X), then, the average value will be used.
  • Once the Orientation Constraints objects are added, it is needed to repotimize.
 
Warning: When creating Orientation Constraints, if the project does not have image geolocation, it is suggested as well to create Scale Constraints to set up a local scale of the model.
 
Example: In the real model, the user knows that the desired orientation regarding the axis X, Y, and Z, then, it is possible to create 3 Orientation constraint having 90º with each other and selecting which object represents which axis, defining a 3 dimensions coordinate system basis.

For step by step instructions on how to draw a new Scale Constraint: 205360385.

Once a new Scale Constraint is created, the right sidebar displays the following information: 202558219.

 

New Orthoplane

An Orthoplane is a tool to create one or several orthophotos of arbitrary areas of the model without having any impact / modifications in the model.

It is created by defining orthoprojection areas that allows to set up:

  • Area of interest (surface and depth).
  • Location.
  • Orientation and direction of the projection.
 
Important: It is important to define properly the box (orthoprojection area):
  • Area of interest (surface and depth).
  • Location.
  • Orientation and direction of the projection.

Only the geometry inside the box (points of the densified point cloud) will be used to find the projection surface.

Once a new Scale Constraint is created, the right sidebar displays the following information: 202558219.

 

New Video Animation Trajectory

An Animation trajectory is a 3D Fly-trough Animation created as a video.

Once a new Animation Trajectory is created, the right sidebar displays the following information: 202558219.

 

 

New Polyline

A Polyline Object is a continuous line composed of one or more sub-lines. It is created by specifying the vertices of each line. For more information about the concept of Polylines: 202559829.

For step by step instructions about how to draw a new Polyline: 202560309.

Once a new Polyline is created, the right sidebar displays the following information: 202558219.

 

New Surface

A Surface is an object that can be used to define planar areas such as a road, the roof of a building, etc. It can also be used to correct the DSM and generate a better orthomosaic on these surfaces.

For step by step instructions about how to draw a new Surface: 202560269.

Once a new Surface is created, the Sidebar displays following information: 202558219.
