Pixol is a unique pixel-based render technology created by Pixologic for 3D/2.5D tool ZBrush. Each pixol contains information about X and Y position and its RGB color values (like a pixel), and additionally about depth, orientation and material. Only ZBrush related files and documents can store information about pixols. Exporting files from ZBrush causes losing pixols equation and turn document into a pixel image. It is not possible to convert pixols to polygons on the fly.

[edit] Pixols in use
In comparison to pixols, 3D object in polygonal based 3D graphics software is a fully rotatable. Pixol object after snapshoting from a 3D object doesn't contains any information about its back side and becomes a part of the canvas. There is only one depth value stored per pixol. In result of this, one pixol cannot be behind another one (it can be done, but by using layers).
