Abstract: In a method of defining an animation of a virtual object, during which values for attributes of the virtual object are updated at each of a series of time points, a user specifies a structure representing the update that includes a plurality of items and one or more connections between respective items. Each item represents a respective operation. Each connection represents that data output by the operation represented by one item is input to the operation represented by the connected item. The user specifies that the structure comprises one or more items in a predetermined category associated with a predetermined process that may be executed at most a predetermined number of times at each time point. An item belongs to the predetermined category if performing the respective operation represented by that item requires execution of the predetermined process. One or more rules are applied.

Abstract: A method of defining an animation of a virtual object within a virtual world, wherein the animation comprises performing, at each of a series of time points, an update that updates values for object attributes of the virtual object, the method comprising: allowing a user to define the update by specifying, on a user interface, a structure representing the update, wherein the structure comprises a plurality of items and one or more connections between respective items, wherein each item represents a respective operation that may be performed when performing the update and wherein a connection between two items represents that data output by the operation represented by one of those two items is input to the operation represented by the other of those two items; allowing the user to specify that the structure comprises one or more items in a predetermined category, the predetermined category being associated with a predetermined process such that an item belongs to the predetermined category if performing the r

Abstract: Computer imaging systems are employed to image, analyze, classify and/or sort seeds and other agricultural items. The systems may be local and/or remote, serial and/or parallel processing, employing various classification schemes including Fisher Linear Discriminant processing and various hardware including a color, digital scanner.
