摘要： Embodiments of this disclosure relate to the technical field of image display, and disclose a 360-degree panorama display method and an electronic device. In some embodiments of this disclosure, a 360-degree panorama display method includes the following steps: acquiring a current viewpoint; establishing a sphere model within a current viewing angle range according to the current viewpoint; rendering the sphere model within the current viewing angle range, so as to generate a three-dimensional image within the current viewing angle range; and displaying the three-dimensional image within the current viewing angle range. By the 360-degree panorama display method and display module, and the mobile terminal provided in the embodiments of this disclosure, the program calculation amount can be reduced and the rendering effect can be improved in a 360-degree panorama display process of the mobile terminal.

摘要： The embodiments of the present disclosure relate to the technical field of virtual reality, and disclose a free viewing method for a three-dimensional video and an electronic device. In some embodiments of the present disclosure, respective rotation matrices of a current viewpoint in three dimensional directions are calculated; a current viewing orientation is calculated according to the rotation matrices in the three dimensional directions and an original viewing orientation; an orientation matrix of a viewer is calculated according to the current viewing orientation; a three-dimensional video is played by using an inverse matrix of the calculated orientation matrix as a position of a three-dimensional video in the coordinate system of the viewer. Adopting the embodiments of the present disclosure enables the display of a three-dimensional video to automatically adapt to a current viewpoint position of a user along with free change of the position of the user.

摘要： A method and a device for constructing a virtual reality model are provided. The method for constructing a virtual reality scene includes the following steps. Generate a space coordinate system of the virtual reality scene. Generate multiple virtual object models of each of multiple virtual objects in the virtual reality scene in the space coordinate system. Integrate the multiple virtual object models to obtain an integrated object model. Map a texture map to the integrated object model to obtain the virtual reality scene model, the virtual reality scene model is programmed to be read and rendered by a display terminal for displaying the virtual reality scene.
