A method comprising: dividing a 3D space into a voxel grid comprising a plurality of voxels; associating a plurality of distance values with the plurality of voxels, each distance value based on a distance to a boundary of an object; selecting an approximate interpolation mode for stepping a ray through a first one or more voxels of the 3D space responsive to the first one or more voxels having distance values greater than a threshold; and detecting the ray reaching a second one or more voxels having distance values less than the first threshold; and responsively selecting a precise interpolation mode for stepping the ray through the second one or more voxels.

Apparatus and method for approximate trilinear interpolation for scene reconstruction

A power converter includes a power stage having a switch-node of a switched-mode power supply that is coupled to an input voltage node by a power field-effect transistor (FET) to energize an inductive circuit and is coupled to a ground node by a synchronous rectifier in parallel with the inductive circuit. The power converter also includes a controller coupled to the power stage. The controller controls switching of the power FET and synchronous rectifier in a complimentary manner. The controller switches on the power FET during a first switching cycle. Subsequently, the controller switches on the synchronous rectifier and, in response to a current through the inductive circuit being approximately zero, switches off the synchronous rectifier. Subsequently, the controller switches on the synchronous rectifier again to generate a negative current through the inductive circuit prior to entering a second switching cycle.
