Embodiments of the present disclosure disclose a three-dimensional path display method, device, computer-readable storage medium, electronic apparatus and computer program product. Therein the method comprises: determining, from a target three-dimensional space, a first sampling-point set comprising points; based on the first sampling-point set, generating a curve indicating the three-dimensional path to be generated; based on the curve, generating the three-dimensional path comprising a path region set, wherein the three-dimensional path passes through the points of the first sampling-point set; determining a mapping relationship between vertices of respective path regions in the path region set and pixels in a preset two-dimensional picture; according to the mapping relationship, inserting corresponding pixels into path regions in the path region set; and displaying the three-dimensional path after the pixels are inserted.

A graphics processing pipeline comprises vertex shading circuitry that operates to vertex shade position attributes of vertices of a set of vertices to be processed by the graphics processing pipeline, to generate, inter alia, a separate vertex shaded position attribute value for each view of the plural different views. Tiling circuitry then determines for the vertices that have been subjected to the first vertex shading operation, whether the vertices should be processed further. Vertex shading circuitry then performs a second vertex shading operation on the vertices that it has been determined should be processed further, to vertex shade the remaining vertex attributes for each vertex that it has been determined should be processed further, to generate, inter alia, a single vertex shaded attribute value for the set of plural views.

A providing apparatus configured to provide three-dimensional geometric data to be used to generate a virtual viewpoint image receives a data request from a communication apparatus, decides which of a plurality of pieces of three-dimensional geometric data including first three-dimensional geometric data and second three-dimensional geometric data with a different quality than the first three-dimensional geometric data is to be provided to the communication apparatus from which the received data request was transmitted, and provides the three-dimensional geometric data decided on from among the plurality of pieces of three-dimensional geometric data, to the communication apparatus as a response to the received data request.

A method of processing an image by a device obtaining one or more images including captured images of objects in a target space, generating metadata including information about mapping between the one or more images and a three-dimensional (3D) mesh model used to generate a virtual reality (VR) image of the target space, and transmitting the one or more images and the metadata to a terminal.

A 3D holographic virtual object display controlling method and apparatus based on human-eye tracking are provided. The display controlling method comprises the following steps of: activating tracking of human eyes of a user; tracking motions of eyeballs of the user; controlling a 3D holographic virtual object presented in a display interface to rotate in response to the motions of the eyeballs of the user; and ending up the tracking of the human eyes of the user. Thereby, the present disclosure can control rotation of a 3D holographic virtual object presented in a display interface by tracking eyeballs and in response to the motions of the eyeballs, which makes the operations convenient and easy.

The disclosure includes a system and method for calibrating a binocular optical see-through augmented reality display. A calibration application renders one or more images of a virtual object on the one or more displays of the human interface device, and receives a user input to adjust a position of the one or more images on the one or more displays. In response to the input, the calibration application identifies a first and second boundary of a target range surrounding a real-world object at a first and second depth, respectively. The calibration application determines a first and second disparity corresponding to the first and second boundary and may record the disparities in relation to the depth of the real-world object.
