The Multiplane Camera

During a recent trip to the Disney Museum in San Francisco, I became immediately fascinated by the multiplane camera that was on display there. The gigantic machine represents so much of what I find inspiring in graphics and technology. It is fun to get lost in thought, imagining what the modern equivalent of the multiplane camera might be and how to foster the intersection of art and technology from which the multiplane camera emerged.

The multiplane camera was invented in 1933 by famous Disney animator/director Ub Iwerks. It worked by enabling animators to position their layers of acetate animation cels at varying distances and offsets in a vertical column. They could then shoot a camera downward to compose the cels into a single frame. While animators had been using acetate celluloid frames composited over painted mattes for decades prior, the technical effects that the multiplane animation camera introduced were an unprecedented leap forward in the field of animation.

What is most interesting about the development of the multiplane camera is that the tools of the animator did not really change much. Acrylic paints were still brushed onto acetate cels, then layered on top of other cels and background mattes, and then captured by a camera. However, armed with the newfound depth and focus components that the multiplane camera enabled, animators could think about their animations in radical new ways. Exciting new animation techniques emerged, like depth of field, parallax, and zooming, as Disney sought to explore the third dimension within their two dimensional animations.

It is fascinating to think about a technology as simple as the multiplane camera unlocking so much potential. It enabled a generation of animators to play in a three-dimensional world decades before Pixar could come along and make it a reality through digital technology. Even then, Pixar animators needed to draw upon the vast base of knowledge captured by early Disney animators in order to capitalize on the nascent and unexplored field of computer animation. The multiplane camera proved to be a catalyst that laid the groundwork for future achievements its inventors could never have anticipated. It was a window into the future of animation.

How wonderful it must have been, whether one knew it or not at the time, to be working on the multiplane camera, the physical manifestation of an inflection point in animation history.

Page Weight Matters

Three years ago, while I was a web developer at YouTube, one of the senior engineers began a rant about the page weight of the video watch page being far too large. The page had ballooned to as high as 1.2MB and dozens of requests. This... Continue →
