SSE Shader Graphs A P P E N D I X A ■ ■ ■ SSE Shader Graphs The Strumpy Shader Editor (SSE) is a flow graph-style editor for making shaders in Unity. It is currently free and can be found in the Unity Asset Store. You can connect directly to the Asset Store from the Window menu inside your Unity project. You can also find different versions of the SSE in the Showcase section of the Unity forum in case you are not using the current Unity build. The SSE BetterLightmap Shader Graph The BetterLightmap shader allows you to blend in just the right amount of emissive with the lightmap and lets you have glossiness and specular for a more realistic lightmapped solution. Figure A-1 shows how the Diffuse component combines diffuse color, a lightmap, and a regular texture. Note the use of the MeshUV node to specify the UV2 mapping channel. This shader can be used on the temple and other main structural objects by selecting their material version appended with a 1. In other words, the Temple Outer material uses a Legacy Lightmap shader while Temple Outer 1 uses the BetterLightmap shader. Both materials use the same lightmap and texture map 939 APPENDIX A ■ SSE SHADER GRAPHS Figure A-1. The SSE BetterLightmap shader graph The SSE ReflectiveAlpha Shader Graph The ReflectiveAlpha shader (Figure A-2) allows you to combine a normal map, alpha channel, and a cube map for reflection. Note the use of the Advanced Shadow Pass to incorporate the opacity information into shadows. This shader is used in the Ledge Fringe object’s material inside the temple. 940 APPENDIX A ■ SSE SHADER GRAPHS Figure A-2. The SSE ReflectiveAlpha shader graph The SSE ReflectiveCutout Shader Graph The ReflectiveCutout shader (Figure A-3) also allows you to combine a normal map, alpha channel, and a cube map for reflection. By subtracting the value of the range node, 0 to 1, from the texture’s alpha channel value, 0 to 1 (black to white), the resulting value will be anywhere from -1 to 1. In the Clip component, any value below 0 is shown as fully transparent. Anything above is fully opaque. In this shader, the outline of the alpha part will be crisper and will appear to sparkle since it doesn’t anti-alias like the alpha blended version. It has the advantage of being rendered in the Geometry pass and is written to the Z buffer. It also needs the Advanced Shadow Pass to incorporate the opacity information into shadows. This shader can be used as an alternative in the Ledge Fringe object’s material inside the temple. Try adjusting the Clamp range to change the clipping amount. 941 APPENDIX A ■ SSE SHADER GRAPHS Figure A-3.

Abstract In photorealistic rendering, the simulation of global illumination is of great percep- tual importance for the generation of convincing imagery. The concepts of light transport for the purpose of rendering are well understood, but expensive to calcu- late. For real-time solutions, simplification is necessary, often at the cost of visual quality. We present a new real-time algorithm for the calculation of global illumination in diffuse scenes. A precomputation step allows for high visual quality with an infinite number of light bounces. Dynamic objects can receive indirect light and don't show temporal artifacts. The proposed technique supports full dynamic lighting and works with all commonly used light source models. In addition, area and environment lighting are facilitated. Furthermore, we present details on how our technique can be implemented on con- temporary hardware. Various approaches are explained and compared to give guide- lines for practical implementation. iv Acknowledgements I would like to express my thanks to my supervisors Jun.-Prof. Dr. Thorsten Grosch and Prof. Dr. Holger Theisel for reviewing this thesis. In addition, M. Sc. Johannes Jendersie has been a great help all throughout the involved research and was very enthusiastic about my work. I would further like to thank Philipp Krause and the great people at Piranha Bytes where I developed a large part of the presented technique.

  • GLOBAL ILLUMINATION in GAMES What Is Global Illumination?
    Nikolay Stefanov, PhD Ubisoft Massive GLOBAL ILLUMINATION IN GAMES What is global illumination? Interaction between light and surfaces Adds effects such as soft contact shadows and colour bleeding Can be brute-forced using path tracing, but is very slow Cornell98 Global illumination is simply the process by which light interacts with physical surfaces. Surfaces absorb, reflect or transmit light. This here is a picture of the famous Cornell box scene, which is a standard environment for testing out global illumination algorithms. The only light source in this image is at the top of the image. Global illumination adds soft shadows and colour between between the cubes and the walls. There is also natural darkening along the edges of the walls, floor and ceiling. One such algorithm is path tracing. A naive, brute force path trace essentially shoot millions and millions of rays or paths, recording every surface hit along the way. The algorithm stops tracing the path when the ray hits a light. As you can imagine, this takes ages to produce a noise-free image. Nonetheless, people have started using some variants of this algorithm for movie production (e.g. “Cloudy With a Chance of Meatballs”) What is global illumination? Scary looking equation! But can be done in 99 lines of C++ All of this makes for some scary looking maths, as illustrated here by the rendering equation from Kajiya. However that doesn’t mean that the *code* is necessarily complicated. GI in 99 lines of C++ Beason2010 Here is an image of Kevin Beason’s smallpt, which is 99 lines of C++ code.

  • Create High-Quality Light Fixtures in Unity
    Expert Guide Create High-Quality Light Fixtures in Unity Pierre Yves Donzallaz Unity Technologies 12 February 2019 (2​nd ​ revision) Introduction A light ​cookie ​is a mask used to block parts of a light source in order to control the shape of the emitted light. They can also be called “gobos”, “cucoloris” or “flags”, depending on the industry and their use case. This expert guide presents several advanced techniques to create high-quality light fixtures in Unity, using 2D and cubemap light cookies, and taking advantage of the advanced shaders available in Unity’s High Definition Render Pipeline. You can use these workflows in projects such as games, architectural visualizations, films, and simulations. Today’s real-time rendering engines cannot render all the intricate shadow details produced by a light fixture: they are unable to produce ray-traced soft shadows efficiently for lower-end platforms, let alone sharp refractive ​caustics​. User-generated cookies can allow for better artistic control of the shadows and the addition of creative details in the lighting. Furthermore, real-time Point Light shadows are still a performance dilemma for modern hardware, so creating environments with a large number of shadow-casting Point lights remains a challenge. This is why baked light cookies are crucial to generate high-quality lighting for real-time applications. Pierre Yves Donzallaz Unity Technologies 2 Pierre Yves Donzallaz Unity Technologies 3 Pierre Yves Donzallaz Unity Technologies 4 Pierre Yves Donzallaz Unity Technologies 5 Common lighting issues In real-time applications, light sources often rely on glowing, detail-less “blobs” to simulate their emissive parts.

  • Abstract Lightmap Generation And
    ABSTRACT LIGHTMAP GENERATION AND PARAMETERIZATION FOR REAL-TIME 3D INFRA-RED SCENES by Meisam Amjad Having high resolution Infra-Red (IR) imagery in cluttered environment of battlespace is crucial for capturing intelligence in search and target acquisition tasks such as whether or not a vehicle (or any heat source) has been moved or used and in which direction. While 3D graphic simulation of large scenes helps with retrieving information and training analysts, using traditional 3D rendering techniques are not enough, and an additional parameter needs to be solved due to different concept of visibility in IR scenes. In 3D rendering of IR scenes, the problem of what can currently be seen by a participant of the simulation does not just depend on emitted thermal energy from objects, and the visibility also depends on previous scenes as thermal energy is slowly retained and diffused over time. Therefore, time as an additional factor must be included since the aggregation of heat energy in the scene relates to its past. Our solution uses lightmaps for storing energy that reaches surfaces over time. We modify the lightmaps to solve the problem of lightmap parameterization between 3D surfaces and 2D mapping and add an extra ability to let us periodically update only necessary areas based on dynamic aspects of the scene.

Many realistic lighting effects such as indirect illumination, ambient occlusion, soft shadows, and caustics are either too complex to render in real-time with today’s hardware or cause significant hits to frame rates.
