Rendering Non-Euclidean Space in Virtual Reality Using Portals

Simulating non-Euclidean geometry in virtual reality is of interest to a wide variety of fields of research. However it is still quite a challenge. Various methods are already known, but they vary greatly in performance and applicability. This paper compares some methods of rendering a non-Euclidean space. We focus on the order-5 square tiling...

Cubemap-based Ambient Occlusion for Character Animation

Simulating lighting is one of the most important parts of rendering 3D scenes. While lighting coming directly from a light source is easy to simulate in real-time, indirect illumination is more difficult. One of the methods used to convincingly approximate indirect illumination is ambient occlusion, where the brightness of objects is reduced...

Ambient Light Caching via Approximate Photon Mapping

Indirect illumination is an essential part of realistic computer-generated imagery. However, accurate calculation of indirect illumination comes at high compute costs. To this end, we replace lengthy indirect illumination paths by employing an ambient light cache based on photon mapping principles. By only performing cache queries after a...

Hardware accelerated ray tracing for diffusion curves

This paper accelerates the rendering of diffusion curves using the ray tracing cores found on modern NVIDIA graphics cards using the method described by Bowers et al. [Bowers, Leahey and Wang 2011]. This method approximates the final result of the Poisson equation and in this paper is accelerated using Optix and dedicated ray tracing hardware....

Multiple viewpoint rendering by exploiting image coherence in epipolar space

In recent years, there has been a widespread increase in the adoption of virtual reality and 3d displays which require many images as input, e.g. head mounted displays or lightfield displays. Real-time rendered imagery for such displays is commonly computed using brute-force rendering pipelines based on forward(+) or deferred rendering pipelines...

Free Viewpoint 3D TV Rendering Platform

Over the past decade, products enabled by 3D technology have been increasingly adopted in the consumer market. The current challenge in the field is to explore the methods of free-viewpoint interpolation for 3D TVs. Free-viewpoint interpolation enhances the user experience significantly by allowing the viewer to select and alter the desired...

3DTV Rendering from Multiple Cameras

In this master's thesis a framework for the rendering of scenes for 3DTV applications is presented. The goal of our work is to investigate ways to generate virtual views of a scene captured using a relatively small number of real cameras. The approach adopted uses per-pixel operations and therefore is suitable for fast parallel implementation. A...
