Detailed Description

Options to configure the constraint to restrict the pitch (tilt) of the camera.

This constraint only works in 3D.

See MapNavigator::getPitchConstraint for more information.

Since: 2021.1

Member Function Documentation

◆ getMaxPitch()

double luciad::MapNavigator::PitchConstraintOptions::getMaxPitch ( ) const

Returns the maximum for the pitch of the 3D camera.

Returns: the maximum pitch value

See also: setMaxPitch

◆ getMinPitch()

double luciad::MapNavigator::PitchConstraintOptions::getMinPitch ( ) const

Returns the minimum for the pitch of the 3D camera.

Returns: the minimum pitch value

See also: setMinPitch

◆ setMaxPitch()

void luciad::MapNavigator::PitchConstraintOptions::setMaxPitch ( double maxPitch )

Sets the maximum for the pitch of the 3D camera.

Pitch is defined as the camera's tilt angle. A value of 0 points the camera towards the horizon (i.e. horizontally); -90 points straight down towards the ground and +90 points straight up.

In other words, this property controls how far the camera can look down.

This camera constraint is only applied on 3D maps.

The default is +89.9, i.e. looking almost straight up.

Parameters

maxPitch the maximum for the pitch of the 3D camera. It is advised not to use a value of 90 or -90. This can lead to the gimbal lock problem, leading to unstable camera movement.

◆ setMinPitch()

void luciad::MapNavigator::PitchConstraintOptions::setMinPitch ( double minPitch )

Sets the minimum for the pitch of the 3D camera.

Pitch is defined as the camera's tilt angle. A value of 0 points the camera towards the horizon (i.e. horizontally); -90 points straight down towards the ground (similar to a 2D top-down view) and +90 points straight up.

In other words, this property controls how far the camera can look up.
