“…To handle data from four cameras with a mobile system,we decided to use two laptops each connected to two cameras.The laptops are synchronized via standard ethernet witha scalable network protocol 3 which serves two purposes:The distribution of parameters (e.g. exposure time) to allcameras, and capture synchronization in time.…”

In this paper we present a novel approach for interactive rendering of virtual views from real image sequences.Combining the concepts of light fields, depth‐compensated image warping and view dependent texture mapping,this plenoptic modeling approach can handle large and complex scenes. A portable, handheld multi‐camera systemhas been developed that allows to record multiple image streams by simply walking around the scene. Theseimage streams are automatically calibrated and depth maps for all views are generated as input to the renderingstage. For rendering a view dependent warping surface is constructed on the fly and depth‐compensated imageinterpolation is applied with view‐dependent texture mapping. Rendering quality is scalable to allow fast previewand to achieve high‐end quality with the same approach. The system can handle large and geometrically complexscenes with hundreds of real images at interactive rates.

“…For framewise synchronization of the graphics clients we need a common decision that all clients have rendered their views and simultaneously display their views after decision concurrently. To guarantee this framewise synchronization of the displays we use the protocol as described in [4].…”

“…This protocol is optimal with respect to the number of messages sent and therefore produces few collisions on the network. In [4] it was measured that the generated time shift between different displays is not noticeable to the user.…”
