Techniques related to non-rigid transformations for articulated bodies are discussed. Such techniques may include repeatedly selecting target positions for matching a kinematic model of an articulated body, generating virtual end-effectors for the kinematic model and corresponding to the target positions, generating an inverse kinematics problem including a Jacobian matrix, and determining a change in kinematic model parameters based on the inverse kinematics problem until a convergence is attained.

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.

A method for displaying virtual content to a user, the method includes determining an accommodation of the user's eyes. The method also includes delivering, through a first waveguide of a stack of waveguides, light rays having a first wavefront curvature based at least in part on the determined accommodation, wherein the first wavefront curvature corresponds to a focal distance of the determined accommodation. The method further includes delivering, through a second waveguide of the stack of waveguides, light rays having a second wavefront curvature, the second wavefront curvature associated with a predetermined margin of the focal distance of the determined accommodation.

A method of digitally making moving picture animation films formed by manipulation of a computer touch screen, the method including the steps of displaying on the screen an image of an array of particulates, such as sand, manipulating the particulates to form a first image, storing a copy of the first image onto computer memory, thereafter altering the first image on the display screen to form a second image and again storing a copy of it to memory, the sequence continuing until a required number of images have been made and stored, and thereafter replaying the stored images in sequence to form a moving picture animation film.

An augmented reality display system comprises a passable world model data comprises a set of map points corresponding to one or more objects of the real world. The augmented reality system also comprises a processor to communicate with one or more individual augmented reality display systems to pass a portion of the passable world model data to the one or more individual augmented reality display systems, wherein the piece of the passable world model data is passed based at least in part on respective locations corresponding to the one or more individual augmented reality display systems.
