Either DirectX or OpenGL can be chosen as the 3D Engine that renders the perspective views of Galleries.  View Options configure the overall appearance and performance of the 3D environment, with Field of View, Resolution and Quality settings.

Gallery Structure parameters determine how Galleries will be randomly constructed, including which styles of Gallery rooms will be built:  Rectangular, Corridor, Rotunda, Labyrinth and/or Billboards.  Either a solid color or a pattern can be chosen for each of the Ceiling, Walls and Floor.  The Alternate Ceiling/Walls/Floor Backgrounds option can be checked to switch those colors or patterns with each new Gallery.  Photo Frames of a specified width and color can be drawn around each image.  Doors to the Previous Gallery and the Next Gallery can be represented either by actual pictures of doors by just by black rectangles.  Optionally, Door Frames/Moldings/Floorboards of a selected color can also appear bordering Walls and Doors.

Exploring parameters control the Relative Velocity of movements and the Motion Smoothness.  The Show Photos option can be set to display each image in full-screen mode for the specified View Seconds.  (While Animate Colors is active View Seconds will be overriden by the Color Seconds value set in the Slide Show Configuration screen).  Photo View Distance determines the position at which to examine each picture.  The Look At While Moving selection controls the direction the viewer will face while traveling to the next image -- either towards the Next Photo, in the Motion Direction or a Random Choice between those two.  Alternatively, the View From Center box can be checked to Explore while remaining in the center of the Gallery, just rotating towards each photo in turn (this option is not applicable in the Labyrinth or Billboards Galleries).  Check Sound Effects to accompany movements within Galleries with sounds to simulate foot steps, turns, door openings, etc.  (Sound Effects are suppressed while the Audio Player is active.)
