Okay, sooooo my fiancée and I have watched both of the 3D versions
of “The Lion King” and “Beauty and the Beast” and here are my thoughts.
First, I would like to make sure that I am not taking for
granted a previous knowledge of terminology thus I took a look at the term dimensionalization. A term defined by NASA as a process of, “offine
conversion of 2D films to 3D stereoscopic films…”.1 The current 2D/3D conversion process of dimensionalization
is very labor-intensive and relies on an artist(s) to rotoscope (to trace or “Transfer
(an image from live action film) into another film sequence…”.2 Many
films flooding the market that are being touted as 3D are actually 2D films
that have been dimensionalized. The
problem that this can present is that 2D films were not filmed with 3D
storytelling techniques in mind and as a result create stereo window violations.
Such was the case with the dimensionalization of “The Lion
King”. The artists who converted the
film were not aware or ignored the stereo window violations that were inherent
to this 2D film conversation i.e. they pushed vertical objects that violated the
stereo window into the negative parallax and as a result created eye
strain. They also employed a technique
of projection of the 2D image onto geometry or 3D modeling which created
unusual and warped effects on the 2D perspective of the original artwork, which
in my opinion was a major gaff and was very distracting as a viewer.
However, Disney learned from their mistakes in “The Lion
King” and made improvements in their dimensionalization of “Beauty and the
Beast”. The depth script for “Beauty and
the Beast” never went into the negative parallax and instead the depth of the
rotoscoped images were either at the plane of the screen or along the positive parallax
and as a result, the film did not have the stereo window violations of “The
Lion King”. They also abandoned the
projection onto geometry technique in favor of traditional rotoscoping.
The only major stereoscopic flaw that I saw with the
dimensionalization of “Beauty and the Beast” was in the opening push into the
castle through the forest. This shot had
too many planes strung out along the z-axis at varying depths and as a result
it created eye strain via excessive parallax.
However, all and all the dimensionalization of “Beauty and the Beast”
was in my opinion a major step forward for Disney over “The Lion King”.
Well, those are my thoughts for the week, I hope you find
them insightful and look forward to your feedback.
Cheers-
