Abstract
The Premo animation platform [Gong et al. 2014] developed by DreamWorks utilized LibEE v1 [Watt et al. 2012] for high performance graph evaluation. The animator experience required fast evaluation, but did not require fast editing of the graph. LibEE v1, therefore, was never designed to support efficient edits. This talk presents an overview of how we developed LibEE v2 to enable fast editing of character rigs while still maintaining or improving upon the speed of evaluation. Overall, LibEE v2 achieves a 100x speedup of authoring operations compared with LibEE v1.
