Abstract: To meet the stringent requirements on simulating motion of an object, a body state of the object needs to be processed in real time while minimizing an error of deviating from the trajectory and time as specified, using limited computing resources. The present disclosure simulates physical aspects of an object in motion by generating a rigid body model that includes external force data and data representing the object. The simulator determines a body state of the object with specific velocity, altitude, and heading at a specific time-tick in real-time. The simulator determines forces applied to the object to move the object and update the rigid model in the real-time process iterations. The disclosed technology uses non-linear inversion dynamics controllers to compute the body forces for following a prescribed trajectory and a rigid body model solver with advanced integration techniques providing low-latency, accuracy, and integrity of linear and rotational body states.

Abstract: In an embodiment, a plurality of graphical elements of a graphical model may be displayed on a display device. An indication of a graphical operation involving a first graphical element of the plurality of graphical elements may be received. The graphical operation when performed may establish a relationship between the first graphical element and one or more other graphical elements of the plurality of graphical elements that are compatible with the graphical operation. Two or more graphical elements of the plurality of graphical elements that are compatible with the graphical operation and one or more characteristics associated with the first graphical element may be identified. A visual indication may be provided on the display device. The visual indication may indicate that the identified plurality of graphical elements is compatible with the graphical operation.
