Definition
2.5 dimensional animation (2.5D) is achieved by taking a 2 dimensional (2D) image or drawing, and animating it in a 3 dimensional (3D) space thus the term 2.5 dimensions. This technique is also called "Postcards in space."
Common tools for such animations are Autodesk's Combustion and Adobe After Effects.
