360 VR #2 - Linearization and 3D Tracking with SynthEyes
In this tutorial, Russ Andersson explores the initial linear mode tracking of a 360VR scene using SynthEyes. He starts by marking the shot as 360VR and explaining the importance of setting the camera's direction and field of view for accurate tracking. Using a script, the shot is converted to a linear view, similar to what you would see in a VR headset. The tutorial covers setting up auto trackers, solving for 3D coordinates, and establishing an initial ground plane using specific trackers. Russ also addresses common issues, such as high tracker errors due to stitching processes and camera synchronization, and demonstrates how to remove less effective trackers to improve the solve. He previews the next stages of the tutorial, focusing on maintaining a stable camera orientation and ensuring the horizon remains level, which is crucial for user orientation in a 360VR environment. The session concludes with a demonstration of global stabilization, highlighting the fixed position of the Sun as an indicator of proper camera orientation.
