Detailed Description

This is a Viewpoint node that produces a view compensated and corrected for perspective effects for a stationary monitor.

The displayed view will look really strange except when viewed from the specified position. The screen location is specified in the same coordindinate system as the view position.

Member Data Documentation

std::auto_ptr< H3D::SFRotation > HVR::SMViewpoint::headOrientation

Specifies the orientation of the head, for stereo eye separation.

This is not the same as the orientation field which will rotate the view on the screen.

std::auto_ptr< H3D::SFVec3f > HVR::SMViewpoint::screenLowerLeft

The position of the lower left corner of the screen.

std::auto_ptr< H3D::SFVec3f > HVR::SMViewpoint::screenUp

The up direction for the screen, as a unit vector.

std::auto_ptr< H3D::SFVec3f > HVR::SMViewpoint::screenUpperRight

The position of the upper right corner of the screen.

std::auto_ptr< SFSinglePointTrackerFilter > HVR::SMViewpoint::tracker

The SinglePointTrackerFilter tracker that defines the position and orientation in world coordinates for this viewpoint.

The tracker's singleTrackerPosition and singleTrackerOrientation fields will be connected to the viewpoint's position and headOrientation fields.

std::auto_ptr< H3D::SFBool > HVR::SMViewpoint::useHeadOrientation

Set this to false if you want to deactivate head tilting.

This can be useful if the tracker provides faulty orientation data.
