Either DirectX or OpenGL can be chosen for 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.  Exploring parameters control the Relative Velocity and Smoothness of movements, the Photo View Distance away from each image to view, and the View Seconds paused to gaze at each image.  The Show Photo option can be set to display each image in full-screen mode.  Movements within Galleries can optionally be accompanied by Sound Effects -- foot steps, turns, doors opening, bumps into walls, etc. (sounds are suppressed while music is playing).  The Look At While Moving selection determines the direction the viewer will face while traveling to the next image.  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.

Gallery Structure parameters determine how Galleries will be constructed, including which styles of Gallery rooms will be built (Rectangular, Corridor, Rotunda and/or Labyrinth) and the Maximum Photos Galleries might contain.  Either a solid color or a pattern can be chosen for each of the Ceiling, Walls and Floor.  Photo Frames can be drawn around each image of a specified width and color.  Doors to the Previous Gallery and the Next Gallery can be represented either by actual pictures of doors by just by black rectangles.  Optionally, Frames/Moldings/Floorboards of a selected color can also appear bordering Walls and Doors, adding a further touch of realism.
