The downside to this approach is that you have to add additional code to each place where knowledge about the camera is used and add these parameters. A common trick in the industry is to represent this as a single camera with additional parameters to control pseudo second eye. Therefore, we should create pairs of cameras to represent a set of eyes. This makes sense because humans have two eyes. This section focuses on how the concepts that are based on human binocular vision are replicated in a S3D world.Īt the base of our representation is a two camera model.
However we will provide formulas for some more advanced setups that allow higher level control over the stereo camera rig such that artists can more easily construct pleasing S3D imagery. This section will not cover these human perceptual rules and assumes the reader has the necessary background before continuing. There are human perceptual rules you must obey to create pleasing images.
It is not enough to simply have two perspective views and call the problem solved. The stereoscopic camera model is based on ability of the human perceptual image to take two unique perspective views and use that information to construct a 3D representation of the real world. Additionally Ray Zone provides a history of S3D cinema. For those readers that do not have a background about S3D or its business case, please refer to Stereoscopic Filmmaking White Paper that provides a comprehensive introduction to S3D and the main business drivers. For those who do not have a programming background, code samples will be offset in separate boxes or included in the appendix so that they can be referenced later or skipped entirely.įinally, we will skip the high level overview of stereoscopic 3D (S3D). This document will be very technical in focus and provides code samples, scripts, and high level mathematics for various components of the S3D pipeline.
We will focus specifically on Autodesk® Maya® software representationsĪnd how technical artists and programmers can take advantage of the core architecture to bring stereoscopic to their next production. This post provides an in-depth discussion and review of stereoscopic cameras.
