Explorations for real time point cloud rendering of natural scenes in virtual reality
This work is a proof of concept, where we explore the possibility of rendering natural scenes in a head mounted display device without meshing. Real time, stereoscopic full HD rendering is obtained for a 14 million points scene, using a low end graphics card for virtual reality (Nvidia GeForce GTX 970) within an Oculus Rift DK2. High quality is achieved by using splatting, while real time rendering is made possible by the means of a good data structure and a complexity reduction of the scene with techniques such as Optimized Sub Sampling, Level of Detail and Frustum Culling. Altogether, those techniques lead to a good virtual reality immersion. Choices and limitations of the proposed techniques are discussed.
