Real-Time Global Illumination Using Precomputed Illuminance Composition with Chrominance Compression
Journal of Computer Graphics Techniques Vol. 5, No. 4, 2016 http://jcgt.org Real-Time Global Illumination Using Precomputed Illuminance Composition with Chrominance Compression Johannes Jendersie1 David Kuri2 Thorsten Grosch1 1TU Clausthal 2Volkswagen AG Figure 1. The Crytek Sponza1 (5.7ms, 245k triangles, 10k caches, 4 band SHs) with a visu- alization of the caches (left) and a Volkswagen test data set using an environment map from Persson2 (10.5ms, 1.35M triangles, 10k caches, 6 band SHs) with multiple bounce indirect illumination and slightly glossy surfaces (right). Abstract In this paper we present a new real-time approach for indirect global illumination under dy- namic lighting conditions. We use surfels to gather a sampling of the local illumination and propagate the light through the scene using a hierarchy and a set of precomputed light trans- port paths. The light is then aggregated into caches for lighting static and dynamic geometry. By using a spherical harmonics representation, caches preserve incident light directions to allow both diffuse and slightly glossy BRDFs for indirect lighting. We provide experimental results for up to eight bands of spherical harmonics to stress the limits of specular reflections. In addition, we apply a chrominance downsampling to reduce the memory overhead of the caches. The sparse sampling of illumination in surfels also enables indirect lighting from many light sources and an efficient progressive multi-bounce implementation. Furthermore, any existing pipeline can be used for surfel lighting, facilitating the use of all kinds of light sources, including sky lights, without a large implementation effort. In addition to the general initial 1Meinl, F. -

Minor Thesis Point Cloud Based Interactive Global Illumination
TECHNISCHE UNIVERSITÄT DRESDEN FACULTY OF COMPUTER SCIENCE INSTITUTE OF SOFTWARE AND MULTIMEDIA TECHNOLOGY CHAIR OF COMPUTER GRAPHICS AND VISUALIZATION PROF.DR.STEFAN GUMHOLD Minor Thesis Point Cloud Based Interactive Global Illumination Mirko Salm (Mat.-No.: 3753374) Tutor: Nico Schertler, M.Sc. Dipl.-Medieninf. Joachim Staib Dresden, 09.03.2015 Aufgabenstellung Globale Beleuchtungseffekte wie indirekte Beleuchtung und Verschattung sind ein signifikanter Faktor für die Realitätsnähe von gerenderten Bildern. Außerdem tragen sie zum besseren Verständnis der Szene bei, indem bspw. die Relationen von Objekten zueinander durch Schatten deutlich werden. Obwohl eine physikalisch korrekte Berechnung der indirekten Beleuchtung möglich ist, sind solche Verfahren sehr rechenintensiv und damit nicht für interaktive Darstellungen geeignet. Ansätze, die Teile der Lichtaus- breitung vorberechnen, können zur Beschleunigung beitragen, jedoch sind diese oft auf statische oder teil-statische Szenen beschränkt. Stattdessen sollen in dieser Arbeit Verfahren untersucht werden, die optisch ansprechende Ergebnisse erzielen. Dabei soll der Fokus auf Effekte der indirekten Beleuch- tung gelegt werden. Nachdem ein fundierter Überblick über solche Verfahren gegeben wurde, soll ein Programm für die Visualisierung von Punktwolken mittels Voxel Cone Tracing implementiert werden. Dabei ist darauf zu achten, dass die Implementierung mit dynamischen Szenen umgehen kann und eine genügend kurze Berechnungszeit aufweist, sodass eine interaktive Visualisierung möglich ist. Die Im- plementierung soll in dem Umfang, den die gewählten Algorithmen erlauben, auf der Grafikkarte laufen. Abschließend ist diese bezüglich Performanz und Qualität zu evaluieren. Teilaufgaben: • Literaturrecherche zu globalen Beleuchtungsmodellen und deren effiziente Implementierung (Light Propagation Volumes, Voxel Cone Tracing, Virtual Point Lights, Instant Radiosity). • Überblick über wesentliche Verfahren zur indirekten Beleuchtung. • Erstellen oder Sammeln von geeigneten Test-Szenen unterschiedlicher Komplexität. -

The thesis is equivalent to 10 weeks of full time studies. The authors declare that they are the sole authors of this thesis and that they have not used any sources other than those listed in the bibliography and identified as references. They further declare that they have not submitted this thesis at any other institution to obtain a degree.

Real-time shadows in 3D applications have for decades been implemented with a solution called Shadow Mapping or some variant of it. This is a solution that is easy to implement and has good computational performance, nevertheless it does suffer from some problems and limitations. But there are newer alternatives and one of them is based on a technique called Voxel Cone-Tracing. This can be combined with a technique called Cascading to create Cascaded Voxel Cone-Tracing Shadows (CVCTS). Objectives. To measure the computational performance of CVCTS to get better insight into it and provide data and findings to help developers make an informed decision if this technique is worth exploring.
