This report describes efforts to apply sketching interfaces to animation. We deal with the problem of sketching 2-D mo­ tion paths for objects to produce animations for applications like Microsoft PowerPoint , Macromedia Flash or Director. We worked on the core problem of editing a sketched mo­ tion curve, using the approach of blending newly sketched motion paths with older paths to allow for ...

We compared two edge-blending methods for multiprojection displays, elliptic and rectangular blending, by simulating three common situations: (1) an inaccurately estimated calibration parameter, (2) a worn projector lamp, and (3) a shifted viewpoint. We used a twolevel-of-detail display including a high-gain rear-projection screen in the simulation to demonstrate an extreme case. The comparison...

Executive summary Task 3.2 is concerned with the development of computational methods for concept blending and their implementation in a Concept Generator prototype. In this deliverable, we present a review of existing computational approaches to conceptual blending used in the development of creative systems. Besides providing an overview of state-of-the-art methods, this study aims (a) to emp...

In constructive solid geometry (CSG), highly smooth and manageable blending operations are always desirable. In this paper, we propose two novel ways to blend implicitly defined geometric objects using smooth unit step functions. With the proposed techniques, not only is it direct to build an implicit blending operation with controllable blending range, but also the blending operation can be co...

This work is concerned with how we can mix conditions of both interpolation and approximation in order to find a blending surface joining two or more surfaces when approximating a given data point set, and modelled from a certain partial differential equation. We establish a variational characterization for the solution of this problem and we establish some convergence result. Finally, we discr...

The blending problem is studied as a problem of finding cheap robust feasible solutions on the unit simplex fulfilling linear and quadratic inequalities. Properties of a regular grid over the unit simplex are discussed. Several tests based on spherical regions are described and evaluated to check the feasibility of subsets and robustness of products. These tests have been implemented into a Bra...

We introduce ontological blending as a method for combining ontologies. Compared with existing combination techniques that aim at integrating or assimilating categories and relations of thematically related ontologies, blending aims at creatively generating (new) categories and ontological definitions; this is done on the basis of input ontologies whose domains are thematically distinct but who...
