In 2004 "The Polar Express" was the first stereoscopic 3D computer-animated feature film. The 3D version was solely release in Imax theaters. In November 2005, Walt Disney Studio Entertainment released "Chicken Little" in digital 3D format, being Disney's first CGI-animated film in 3D. The film was converted from 2D into 3D in post production. nWave Pictures' Fly Me To The Moon 3D (2008) was actually the first animated film created for 3D and released exclusively in 3D in digital theaters around the world. No other animation films have released solely in 3D since. The first 3D feature by DreamWorks Animation, "Monsters vs Aliens", followed in 2009 and used a new digital rendering process called InTru3D, which was developed by Intel to create more realistic animated 3D images. InTru3D is not used to exhibit 3D films in theaters; they are shown in either RealD 3D or IMAX 3D.
