An image processing apparatus includes detection circuitry and processing circuitry. The detection circuitry, in operation, detects a position on a sensor that is pointed to by a pointer. The processing circuitry, in operation, generates three-dimensional data that includes the position detected by the detection circuitry, positions a two-dimensional surface relative to the position detected by the detection circuitry, and applies rendering to, at least, part of the three-dimensional data that is arranged on one side of the two-dimensional surface to be displayed on a display screen.
