Abstract: A collaborative virtual reality (VR) online meeting platform that includes a three-dimensional (3D) point cloud data defining a virtual space, identifiers of a plurality of meeting participants, and meeting data that includes positions in the virtual space of a plurality of avatars that correspond to meeting participants. The system includes a processor that includes instructions to initiate an online meeting of the plurality of meeting participants. The initiating includes providing an address of the 3D point cloud to each of the meeting participants and transmitting a copy of the 3D point cloud data and meeting data to each of the meeting participants. A current location of each of the avatars in the virtual space is communicated to all of the meeting participants.

Abstract: A virtual reality (VR) system that includes a three-dimensional (3D) point cloud having a plurality of points, a VR viewer having a current position, a graphics processing unit (GPU), and a central processing unit (CPU). The CPU determines a field-of-view (FOV) based at least in part on the current position of the VR viewer, selects, using occlusion culling, a subset of the points based at least in part on the FOV, and provides them to the GPU. The GPU receives the subset of the plurality of points from the CPU and renders an image for display on the VR viewer based at least in part on the received subset of the plurality of points. The selecting a subset of the plurality of points is at a first frame per second (FPS) rate and the rendering is at a second FPS rate that is faster than the first FPS rate.
