Method and system for real-time rendering displaying high resolution virtual reality (VR) video
A method and a system for rendering VR video are disclosed. In the method, a base video model and an enhancement video model are built respectively, with UV coordinates being initialized. base video segments and enhancement video segments are obtained according to a user's viewport. A base video texture is generated according to pixel information of the base video segments and the UV coordinates of the base video model. An enhancement video texture is generated according to pixel information of the enhancement video segments and the UV coordinates of the enhancement video model. Pixel information is reconstructed by adding the base video texture and the enhancement video texture with each other according to alignment coordinates. An image is drawn according to the reconstructed pixel information. The method reduces data transmission and improves rendering efficiency without affecting the user's viewing experience.
