Detailed Description

Allows to customize the Vg3DManipulator.

Remarks

The default manipulator for most maps is the "2D" manipulator.

For example, if you wanted to change the minimum altitude to 100

std::string lCurrentManipulator = lApplication->editManipulatorManager()->getCurrentManipulator();
VgApplication::VgManipulator* lManipulator = lApplication->editManipulatorManager()->editManipulatorObject(lCurrentManipulator);

if (lManipulator != NULL || lCurrentManipulator == "3D")
{
   VgApplication::Vg3DManipulator *l3DManipulator = (VgApplication::Vg3DManipulator *)lManipulator;
   VgEngine::VgPosition lMin, lMax;
   bool lStatus = l3DManipulator->getBoundaries(lMin,lMax);
   lMin.mZOrAltitude = 100;
   bool lStatus = l3DManipulator->setBoundaries(lMin,lMax);
}

Member Function Documentation

virtual bool VgApplication::Vg3DManipulator::getBoundaries ( VgEngine::VgPosition &  pMinimumPosition, VgEngine::VgPosition &  pMaximumPosition  ) const

pure virtual

Retrieves the current boundaries of the camera.

Parameters

pMinimumPosition	Updates with the minimum latitude, longitude, and altitude the camera is allowed to move.
pMaximumPosition	Updates with the maximum latitude, longitude, and altitude the camera is allowed to move

Returns

true.

virtual std::string VgApplication::Vg3DManipulator::getType ( ) const

pure virtual

Returns

The type identifer of the Vg3DManipulator class.

Implements VgApplication::VgManipulator.

virtual bool VgApplication::Vg3DManipulator::setBoundaries ( const VgEngine::VgPosition &  pMinimumPosition, const VgEngine::VgPosition &  pMaximumPosition  )

pure virtual

Set the boundaries where the camera can move.

If the current camera position is outside this new boundary, the camera will be moved inside this new area.

The original values for the manipulators are set on the vg_config.xml or via the default values of the dataset It is usually smaller than that found on the dataset.

Remarks

you can use this URL https://developers.google.com/maps/documentation/utilities/polylineutility to try out different values

Setting the minimum and maximum altitude (mZOrAltitude) to be the same will still allow some interaction with the manipulator due to the "bounce" effect when one reaches the limits.

The actual altitude boundaries are affected by other internal parameters (notably mMinimumDistanceFromGround which usually has value of 2)

Parameters

pMinimumPosition	Minimum latitude, longitude, and altitude the camera is allowed to move.
pMaximumPosition	Maximum latitude, longitude, and altitude the camera is allowed to move. It supposes the all the values are greater than the values in pMinimumPosition

Returns

true.
