Abstract

A method for calculating a series of frames of video data, comprising grouping a plurality of architectural data elements into a plurality of threads using a processor. Calculating a frame part of animation data for each of the threads. Determining a calculation time for each of the threads. Modifying the grouping of the plurality of architectural data elements as a function of the calculation time for each of the threads.

Claims

1. A method for calculating a series of frames of video data, comprising:

grouping a plurality of architectural data elements into a plurality of threads using a processor;

calculating a frame part of animation data for each of the threads;

determining a calculation time for each of the threads; and

modifying the grouping of the plurality of architectural data elements as a function of the calculation time for each of the threads to achieve the same calculation time.

2. The method of claim 1 wherein grouping the plurality of architectural data elements into the plurality of threads using the processor comprises grouping the plurality of architectural data elements into the plurality of threads as a function of a display order for each of the architectural data elements.

3. The method of claim 1 wherein grouping the plurality of architectural data elements into the plurality of threads using the processor comprises grouping the plurality of architectural data elements into the plurality of threads as a function of a calculation time for each of the architectural data elements.

4. The method of claim 1 wherein determining the calculation time for each of the threads comprises determining the calculation time for a plurality of threads.

5. The method of claim 1 wherein modifying the grouping of the plurality of architectural data elements as the function of the calculation time for each of the threads comprises assigning one or more architectural data elements from a first thread to a second thread.

6. The method of claim 4 wherein modifying the grouping of the plurality of architectural data elements as the function of the calculation time for each of the threads comprises assigning one or more architectural data elements from a first thread having an associated calculation time that is greater than the associated calculation time of a second thread.

7. The method of claim 1 wherein modifying the grouping of the plurality of architectural data elements as the function of the calculation time for each of the threads comprises assigning one or more new architectural data elements to a first thread.

8. The method of claim 1 further comprising modifying the grouping of the plurality of architectural data elements as a function of a change in position of an animation sequence.

9. The method of claim 1 further comprising modifying the grouping of the plurality of architectural data elements as a function of a change in a point of view of an animation sequence.

10. A system for calculating a series of frames of video data, comprising:

a building model system storing a plurality of architectural data elements; and

a frame calculation system operating on a processor and configured to retrieve the plurality of architectural data elements form the building model system and to calculate a frame of video data, wherein the frame calculation system further comprises an element allocation system configured to assign each of the plurality of architectural data elements to one of a plurality processing threads.

11. The system of claim 10 wherein the frame calculation system further comprises an element order system configured to determine an order of the architectural data elements prior to the assignment of the plurality of architectural data elements to one of the plurality processing threads.

12. The system of claim 11 wherein the element allocation system is configured to assign the plurality of architectural data elements to one of the plurality processing threads as a function of the order of the architectural data elements.

13. The system of claim 10 wherein the frame calculation system further comprises an element order system configured to determine a display order of the architectural data elements prior to the assignment of the plurality of architectural data elements to one of the plurality processing threads, and wherein the element allocation system is configured to assign the plurality of architectural data elements to one of the plurality processing threads as a function of the display order.
