Application of foveal rendering technology to optimize the performance of complex scenes of virtual historical reconstruction

Authors examine a problem of increasing a frame rate during highload scenes rendering for virtual historical reconstruction of Bely Gorod. The reconstruction is designed to be rendered using a virtual reality headset. To improve performance, authors implemented a foveated endering technique. It allows to display in high resolution only the area of the scene that the user is currently looking at. A new gaze tracking system was developed and tested, and frame rates were compared for the Bely Gorod scene.
