摘要： A rendering device that renders a three-dimensional object displayed in a virtual reality space on a display includes a processor and a memory storing instructions that, when executed by the processor, cause the processor to render the 3D object as a 3D object of 3D displaying in a virtual reality space coordinate system, render the 3D object as a 3D object of 2D displaying in a plane coordinate system, and update displaying of the display based on a result of the 3D object being rendered as the 3D object of 3D displaying in the virtual reality space coordinate system and a result of the object being rendered as the 3D object of 2D displaying in the plane coordinate system. The rendering device enables intuitive drawing with high accuracy in the virtual reality space.

摘要： A position pointer includes a signal generation circuit, which generates at least one signal. The position pointer in operation transmits the at least one signal to a sensor of a position detector. The position pointer includes a first electrode arranged to protrude from one end portion of a pen-shaped housing along an axial center direction and a second electrode including at least three electrode pieces disposed near the first electrode in such a manner as to surround a central axis of the housing. The at least three electrode pieces are electrically isolated from each other. The position pointer has a signal supply control circuit, which, in operation, controls supply of signals to selectively supply the at least one signal to the second electrode that includes the at least three electrode pieces and to the first electrode.

摘要： A position indicator that indicates a position is disclosed. The position indicator includes a casing of an electronic pen, a position indicating part, a tracker, and a grip part configured to be gripped by a user. The position indicating part is disposed at one end of the casing. The position indicating part, in operation, indicates the position. The tracker, in operation, causes an external device to detect the position in a three-dimensional space. The grip part is orthogonal to the casing of the electronic pen.

摘要： A rendering device that renders an object in a virtual reality space includes a processor and a memory storing instructions that, when executed by the processor, cause the processor to perform a first rendering process that renders in the virtual reality space an image of an input surface on which a position is indicated by a stylus, perform a second rendering process that renders in the virtual reality space an image of a display surface that displays the object, the image of the display surface being different from the image of the input surface, perform an acquisition process that acquires the position on the input surface indicated by the stylus, and perform a display process that displays the object in the image of the display surface based on the position on the input surface acquired by performing the acquisition process.

摘要： A position indicator indicates a position on an input surface of a position detecting sensor and indicates a position in a three-dimensional space. The position indicator incudes: a casing, a position indicating part that is disposed at one end of the casing, and a tracker which, in operation, causes an external device to detect the position in the three-dimensional space. The position indicating part, in operation, indicates the position on the input surface of the position detecting sensor. A position of the tracker and a position of the position indicating part are in a specific positional relation.

摘要： A position indicating device includes a housing, a position indicator which, in operation, indicates a position, a first pressure sensor which, in operation, detects a pressure applied to the position indicator, a second sensor which, in operation, detects a second pressure applied to the housing, a first communication circuit which, in operation, transmits the pen pressure detected by the pen pressure sensor, and a second communication circuit which, in operation, transmits the gripping force detected by the gripping force sensor. The position indicating device enables control of a line width and transparency in a preferable manner even when there is no actual touch surface.
