Abstract: A method reducing a motion sickness effect associated with a rendering of a video on a virtual reality device includes: extracting, from a portion of the video, at least one motion parameter that relates to a motion of a camera used for capturing the video, determining, based on the extracted at least one motion parameter, at least one motion sickness reduction scheme to be applied to the video, and dynamically rendering the video to the virtual reality device by applying the determined motion sickness scheme to the portion of the video.

Abstract: A method for selective magnification in a 3D rendering system includes: displaying, by an electronic device, a first view including at least one real world object and at least one virtual object; displaying, by the electronic device, a second view comprising a region of interest (ROI) in the first view, while displaying the first view; receiving, by the electronic device, a user interaction on the second view; and generating, by the electronic device, interaction on the first view corresponding to the user interaction received on the second view.

Abstract: A method and apparatus for rendering point cloud-based volumetric data are provided. The method includes receiving, at a computing device, a plurality of two-dimensional (2D) frames associated with a three-dimensional (3D) point cloud, and projection metadata comprising details of projection of the 3D point cloud into a 2D image plane; reconstructing, by the computing device, a plurality of 3D points associated with the 3D point cloud, based on the received 2D frames and the projection metadata; and generating texture images based on the plurality of 3D points; and rendering at least one quad image based on the texture images.

Abstract: An apparatus and method are provided for compressing a three-dimensional (3D) object image represented by point cloud data. The method includes positioning the 3D object image into a plurality of equi-sized cubes for compression; determining 3D local coordinates in each of the plurality of equi-sized cubes and a cube index for each point of the 3D object image positioned in the plurality of equi-sized cubes; generating two-dimensional (2D) image data based on the 3D local coordinates and the cube indexes; and storing the 2D image data in a memory. The 2D image data includes at least one of 2D geometry data, 2D meta data, or 2D color data.
