<span class=normal>Photomodelling/cameratracking and matchmoving<BR><br><p class=clear>&nbsp;</p>Photomodels are basic rough polygon models that are built by using a series of photographs taken at different angles on the set. They are built for props that are seen in the shot. The purpose for building these models is to verify the quality of the camera tracks. Also, these models are built to the actual scale of the props on set for which a separate set of measurements is taken. This helps us to verify any issues in terms of scale and size. After the photomodels were built, the trackers imported the models into their files and started off with the camera tracking and matchmoving work. Apart from the photomodels, the trackers also used the crocodile model as a quality check for the camera tracks and also to check scaling issues. <BR><BR><br><p class=clear>&nbsp;</p>BgPrep<BR> <br><p class=clear>&nbsp;</p>The BgPrep and Tracking stages go on in parallel. The BgPrep stage literally means prepping up the Bg for other departments down the line to use it. Wires and rigs removal, marker removal etc. are some of the tasks done at this stage. <BR><BR><br><p class=clear>&nbsp;</p>Rigging<BR><br><p class=clear>&nbsp;</p>Since we already had a basic rig in place which was done at the pre-visualization stage, the riggers just finessed it further by making it more flexible and adding in more controls. For eg. - controls for the eye bulge, controls for the mouth bulge etc. </span>
