Volumetric displays allow users to view freely three-dimensional (3D) imagery without special eyewear. However, due to low display resolution, many colors appear distorted compared to their representation on a flat-panel display. In addition, due to the unique nature of the display, some shapes, objects, and orientations can also appear distorted. This study examines the perceptual range of virtual objects in a Perspecta 3D volumetric display to determine which combination of object type, size, and color produces the best 3D image. Participants viewed combinations composed of three object types (vertical square plane, empty cube, filled cube) x three sizes (small, medium, large) x seven colors (aqua, blue, green, purple, red, white, yellow). They named the color of the object and then rated the uniformity of the color, the quality of the shape, amount of visual flicker, and the solidity of the object. All dependent measures except the rating of solidity exhibited various main and interaction effects among object type, size, and color.
