Detailed Description

A description of the display screen for projection-based VR systems. This is used together with a head position and orientation to setup the appropriate projection matrix for head-tracked rendering.

Important: After setting or changing any of the variables that define the postion of the tile (top*, bot*), calculateRoomToTile() needs to be called to update the room2tile matrix.

Member Function Documentation

void VRG3D::DisplayTile::calculateRoomToTile (  ) 

Calculates the appropriate room2tile matrix based on the location of the tile. room2tile is cached in this class for speed and used by ProjectionVRCamera each frame. If you change the position of the tile, you should call this to recalculate the room2tile matrix.

static const DisplayTile& VRG3D::DisplayTile::defaultDesktopTile (  )  [static]

Default setup for a desktop display.
