Abstract
To prevent correlated data from being inadvertently altered by subsequent modifications or additions, changes to correlated data are automatically detected. Corrections may be automatically applied to data to preserve data correlation. Change detection data is determined from an initial correlation between source data and dependent data. The change detection data is stored in association with the dependent data. A subsequent evaluation of the data defines a current correlation between the source data and the dependent data. The current correlation is evaluated with the change detection data to determine if the current correlation differs from the initial correlation. If the current correlation between source data and dependent data does not match the initial correlation, the current correlation is reevaluated using topological; geometric, or other analysis techniques. The reevaluated correlation can be provided as part of the authored state of a computer graphics component.
