One embodiment of the present invention provides a technique for generating a three-dimensional model from a two-dimensional sketch. The technique includes receiving input indicating a set of points defining a first sketch element and a second set of points defining a second sketch element included in a sketch. The technique further includes identifying one or more design relationships between the first sketch element and the second sketch element. The technique further includes generating a computer model of the sketch that represents a structure linking the first sketch element and the second sketch element according to the one or more design relationships. The technique further includes outputting the first sketch element, the second sketch element, and the structure for display.

Three-dimensional generative design based on two-dimensional sketching

A sketch-based interface within an animation engine provides an end-user with tools for creating emitter textures and oscillator textures. The end-user may create an emitter texture by sketching one or more patch elements and then sketching an emitter. The animation engine animates the sketch by generating a stream of patch elements that emanate from the emitter. The end-user may create an oscillator texture by sketching a patch that includes one or more patch elements, and then sketching a brush skeleton and an oscillation skeleton. The animation engine replicates the patch along the brush skeleton, and then interpolates the replicated patches between the brush skeleton and the oscillation skeleton, thereby causing those replicated patches to periodically oscillate between the two skeletons.

Animating sketches via kinetic textures

In one embodiment, a dynamic effects subsystem automatically generates a dynamic effects animation. A graphical user interface enables an animator to sketch applied energies that influence graphical objects. Each applied energy includes flow particles that are associated with velocity fields. Over time, a dynamic effects engine moves the flow particles and the associated velocity fields along a overall direction associated with the applied energy. To generate each frame included in the dynamic effects animation, the dynamic effect engine computes samples of the graphical objects, computes the influences of the velocity fields on the samples, and updates the positions of the samples based on the influences of the velocity fields. Notably, the applied energies and the flow particles enable the animator to effectively and interactively control the automated animation operations of the dynamic effects engine. Consequently, the resulting dynamic effects animation meets artistic, performance, and physical accuracy goals.

Techniques for generating dynamic effects animations

A computer-implemented method for editing an interactive dynamic illustration includes receiving a first input associated with a functional relationship between a first visual entity in the dynamic illustration and a second visual entity in the dynamic illustration, receiving a second input that associates a visual parameter of the first visual entity with the functional relationship, and receiving a third input that associates a visual parameter of the second visual entity with the functional relationship. The method further includes causing a graphical representation of the functional relationship to be displayed that visually links the first visual entity and the second visual entity. At least one advantage of the disclosed method is that a user can graphically define and/or modify interactive behavior of the visual elements of an interactive dynamic illustration without textually editing the software that generates the illustration.
