    Patent number: 11250641
    Abstract: Mating virtual objects in virtual reality environment, involves generating a bounding box having a plurality of faces corresponding to a plurality of exterior surfaces of a subject virtual object. A spatial mesh corresponding to surfaces of the real world environment is generated. A magnetic mate is generated to initially align a bounding box first face to a first spatial mesh surface. A shadow mate is provided between a bounding box second face and a second spatial mesh surface, by projecting a virtual ray from the subject virtual object bounding box second face toward the second spatial mesh surface, determining a mate point corresponding to an intersection of the virtual ray and the second spatial mesh surface, and displaying a mating button in the virtual reality environment at the mate point.

  • Simulation of robotic painting for electrostatic wraparound applications
    Patent number: 11232244
    Abstract: Embodiments simulate electrostatic painting on a real-world object. An embodiment begins by receiving an indication of paint deposition rate and an indication of maximum paint accumulation for a given real-world robotically controlled electrostatic paint gun. Next, paint deposition of the given real-world robotically controlled electrostatic paint gun in a virtual environment is represented which includes, for a subject time period, computing total paint accumulation (electrostatic and direct) on a given surface element of a model representing the real-world object. In turn, a parameter file is generated that includes parameters accounting for the determined total paint accumulation for the given surface element, where the generated parameter file enables precision operation of the given real-world robotically controlled electrostatic paint gun to paint the real-world object.
