Animation: Growing a Tree in Maya

Before I begin, I would like to touch on the history of 3D animation.

Although there was experimentation with computer graphics prior to the 1980’s, 3D photo-realistic graphics didn’t truly take shape until the first movie to use solid 3D computer generated imagery.  That movie was TRON, in 1982.  (I don’t mean to discredit all of the prior work leading up to TRON, but it would take a short novel to describe all the accomplishments of John Whitney, Lawrence Livermore, Ivan Sutherland and many other individual and institutional contributions.)

The 80’s brought an explosion of hardware and software introductions which only increased experimentation with 3D graphics.

By the 1990’s, the use of 3D animation became a common tool in cinema.  1991 is considered the “breakout year” for heavy use of CGI.  Terminator 2 and Beauty and the Beast both heavily used CGI to produce awe inspiring animation of robots and scenes to intrigue movie goers.

The expansion of more software programs throughout the 90’s finally led to a breakthrough in 2000.  Capture of the reflectance field over the human face and full virtual cinematography.

3D animation continues to expand with ever changing technology.  Most recently, it has found much success in the production of life like graphics in the gaming industry.

You may make adjustments to the appearance of the tree under the Growth tab.  I like to adjust the branches and leaves.
