Method and Arrangement for Determining Current Projection Data for a Projection of a Spatially Variable Area

The method as claimed in claim 1, further comprising the step of storing data selected from the group consisting of said first current projection data and said second current projection data.

The method as claimed in claim 1, further comprising the steps of:

• transmitting, by said first computing unit, a first synchronization information item to said second computing unit;
• and
• transmitting, by said first computing unit, a second synchronization information item to said third computing unit, said steps of transmitting said first and said second synchronization items being utilized for synchronizing processes for said step of determining said first and said second current projection data.

The method as claimed in claim 1, further comprising the steps of:

• transmitting, by said first computing unit, a third synchronization information item to said second computing unit;
• and
• transmitting, by said first computing unit, a fourth synchronization information item to said third computing unit, said steps of transmitting said third and said fourth synchronization items being utilized for synchronizing said first and said second projection.

The method as claimed in claim 3, wherein said first or said second synchronization information item is a broadcast message of a broadcast mechanism.

The method as claimed in claim 1, wherein said spatially variable area is described by a scene graph.

The method as claimed in claim 7, further comprising the step of:

• determining said change in said spatially variable area from a change in said scene graph of said spatially variable area in said starting state with respect to said scene graph of said spatially variable area in said end state.

The method as claimed in claim 1, wherein said spatially variable area in said starting state or said spatially variable area in said end state is contained in a 3D image.

The method as claimed in claim 9, further comprising the steps of:

• projecting 3D images of a 3D image sequence;
• and
• determining said scene graph for each 3D image of said 3D image sequence.

The method as claimed in claim 10, further comprising the steps of:

• generating 3D images using a system selected from the group consisting of a virtual reality system and a visual simulation system.

The arrangement as claimed in claim 12, wherein said first projection and said second projection are configured to be synchronized.

The method as claimed in claim 4, wherein said third or said fourth synchronization information item is a broadcast message of a broadcast mechanism.
