System and method for animating collision-free sequences of motions for objects placed across a surface

Номер: US20130033501A1
Автор: Michael Girard, Susan AMKRAUT
Принадлежит: Autodesk Inc

Embodiments of the invention set forth a technique for animating objects placed across a surface of a graphics object. A CAD application receives a set of motions and initially applies a different motion in the set of motions to each object placed across the surface of the graphics object. The CAD application calculates bounding areas of each object according to the current motion applied thereto, which are subsequently used by the CAD application to identify collisions that are occurring or will occur between the objects. Identified collisions are cured by identifying valid motions in the set of motions that can be applied to a colliding object and then calculating bounding areas for the valid motions to select a valid motion that, when applied to the object, does not cause the object to collide with any other objects.

Parallax image authoring and viewing in digital media

Номер: US20130127826A1
Автор: Daniel Alan Wabyick, Robert Benson Walton
Принадлежит: Adobe Systems Inc

An authoring tool assigns a first depth value to a first image layer and a second depth value to a second image layer. The first depth value is a first simulated distance from a user. The second depth value is a second simulated distance from the user. The authoring tool composes an image based on the first image layer and the second image layer such that the image is displayed within a page in a scrollable area on a viewing device. The first depth value is utilized to generate a first offset value from a first static position of the first image layer and the second depth value is utilized to generate a second offset value from a second static position of the second image layer based upon a scroll position of the page with respect to a target location in the scrollable area to create a parallax effect.

Discrete objects for building virtual environments

Принадлежит: Microsoft Corp

Described is a virtual environment built by drawing stacks of three-dimensional objects (e.g., discrete blocks) as manipulated by a user. A user manipulates one or more objects, resulting in stack heights being changed, e.g., by adding, removing or moving objects to/from stacks. The stack heights are maintained as sample points, e.g., each point indexed by its associated horizontal location. A graphics processor expands height-related information into visible objects or stacks of objects by computing the vertices for each stack to draw that stack's top surface, front surface and/or side surface based upon the height-related information for that stack. Height information for neighboring stacks may be associated with the sample point, whereby a stack is only drawn to where it is occluded by a neighboring stack, that is, by computing the lower vertices for a surface according to the height of a neighboring stack where appropriate.

A sensor(s), such as a video camera, can track and monitor a geographic location, such as a road, pipeline, or other location or installation. A video analytics engine can receive video streams from the sensor, and identify a location of the imaged view in a geo-registered map space, such as a latitude-longitude defined map space. A user can operate a graphical user interface to draw, enter, select, and/or otherwise input on a map a set of rules for detection of events in the monitored scene, such as tripwires and areas of interest. When tripwires, areas of interest, and/or other features are approached or crossed, the engine can perform responsive actions, such as generating an alert and sending it to a user. 1. A computer implemented method to generate video analysis rules , comprising:displaying, on a map based user interface, a map of a geographic area, at least a portion of the geographic area covered by a video sensor;accepting, via the map based user interface, a rule-representing feature that is placed in a specific location on the map by a user;generating a video analysis rule based on the rule representing feature and the specific location on the map, wherein the video analysis rule is expressed in a geo-registered map spacereceiving video from the video sensor; andapplying the video analysis rule to the video from the video sensor to detect an event.2. The method of claim 1 , further comprising notifying a generating a notification on detection of the event.3. The method of claim 1 , wherein the rule-representing feature is a tripwire.4. The method of claim 1 , wherein the rule-representing feature is an area of interest.5. The method of claim 1 , wherein the geo-registered map space is defined in coordinates that are latitude and longitude coordinates.6. The method of claim 1 , wherein the video provided by the sensor ...
