摘要： A wellbore tool for locating a target wellbore containing a conductive member from a second wellbore and directing the trajectory of the second wellbore relative to the target wellbore includes an electric current driver having an insulated gap; a three-axis magnetometer positioned within a non-magnetic housing that is disposed within a non-magnetic tubular, the three-axis magnetometer positioned below the electric current driver; a drill bit positioned below the three-axis magnetometer; a hollow tubular connected between the electric current driver and the three-axis magnetometer; and a measurement-while-drilling tool. The current driver generates an electric current across the gap to the portion of the tool below the insulated gap. In a method a current is generated across the insulated gap to the portion of the tool below the insulated gap to the conductive material in the target wellbore returning to a portion of the bottom hole assembly above the insulated gap thereby producing a target magnetic field. Measuring the target magnetic field at the bottom hole assembly and the earth's magnetic field; and determining the position of the second wellbore relative to the target wellbore. Then steering the bottom hole assembly to drill the second wellbore along a trajectory relative to the target wellbore.

摘要： Procedure for rendering images in real time of three-dimensional models of items of jewellery Procedure for rendering images in real time of three-dimensional models of items of jewellery comprising at least one transparent or translucent stone having facets, which procedure comprises the steps consisting in determining a reference point in the stone, calculating the components of the normals to the facets of the stone in a discrete set of directions around the reference point and storing these components in a map of the normals, and simulating light reflections within the stone by calculating an approximation of the point of intersection between a ray and the stone using a simplified geometric shape of the stone and using, to calculate the direction of the reflected ray, a normal extracted from the map of the normals, corresponding to the point of the surface of the stone located in the direction of the point relative to the reference point.
