In this work we design a tool for creators of interactive stories to explore the effect of applying camera patterns to achieve high level communicative goals in a 3D animated scenario. We design a pattern language to specify high level communicative goals that are translated into simple or complex camera techniques and transitions, and then flexibly applied(More)
We propose a principled method to specify XML document transformation so that the outcome of a transformation can be ensured to conform to certain structural constraints as required by the target XML document type. We view XML document types as graphs, and model transformations as relations between the two graphs. Starting from this abstraction, we use and(More)
The first and second hyperpolarizability beta and gamma are obtained for formaldehyde oligomers (H2CO)n (n = 1-7) using computational methods. We have used the finite field (FF) approach and hyperpolarizability density analysis (HDA) to predict the microscopic first and second nonlinear hyperpolarizability of the formaldehyde oligomers. The spatial(More)
