Download or read book Forward and Inverse Rendering with Gradient based Optimization written by Fujun Luan and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photorealistic rendering is a fundamental component of computer graphics. To render photorealistic 2D images that faithfully represent our 3D world, efforts have been devoted into developing compact scientific models and efficient algorithms that are capable of simulating lighting and physics to capture appearance using the geometry, reflectance and illumination. Inverse Rendering, on the other hand, focuses on recovering unknown scene attributes from photograph measurements by optimization, typically through analysis-by-synthesis technique, or more recently, differentiable rendering. In this thesis, we propose solutions to a few such challenging forward and inverse graphics problems, as described below. The first work is a forward rendering (SIGGRAPH 2020) approach to speeding up Markov chain Monte Carlo (MCMC) rendering with derivatives from recent rendering engines that support end-to-end differentiation. In this work, we build upon Langevin dynamics and propose a suite of Langevin Monte Carlo algorithms with gradient-based adaptation for efficient photorealistic rendering of scenes with complex light transport effects, such as caustics, interreflections, and occlusions. In inverse rendering, we develop multiple solutions for recovering material and shape. In our second work (ICCP 2020) we focus on learning-based inverse subsurface scattering. Given images of transcluent objects, of unknown shape and lighting, we aim to use learning to infer the optical parameters controlling subsurface scattering of light inside the objects. With physics-based priors in the learning framework, we obtain strong improvements in both parameter estimation accuracy and appearance reproduction compared to traditional networks. Our third work is a unified shape and appearance reconstruction framework (EGSR 2021) using differentiable rendering for 3D object scanning. We tackle this problem by introducing a new analysis-by-synthesis technique capable of producing high-quality reconstructions through robust coarse-to-fine optimization and physics-based differentiable rendering. We demonstrate the effectiveness of our method on real-world objects captured with handheld cameras that outperforms previous state-of-the-art approaches. In Appendix A, we tackle the challenge of automatically generating procedural representation of fiber-based yarn models for cloth rendering (SIGGRAPH 2016, EGSR 2017). Appendix B has slightly deviated from rendering and focuses on image style transfer techniques (CVPR 2017, EGSR 2018). With recent advances in physics-based differentiable rendering, we have taken first steps to speeding up MCMC forward rendering with first-order gradients, improving learning-based inverse subsurface scattering, and introducing an end-to-end differentiable rendering pipeline for high-quality handheld object scanning. As for next steps, a promising future direction for computer graphics would be learning-based neural rendering methods that aim for AR/VR-based applications. Exploring differentiable rendering for improving traditional 3D reconstruction would be another promising topic, thanks to the theoretical and practical breakthroughs in the corresponding field.

Book excerpt: To be human is to express--not only facts about the world, but also experiences, emotions, and ideas. We paint, explain, compose, persuade, dance, teach, sculpt, and sing, not merely to communicate bits of information from person to person, but rather to fan the windmills of one another's minds. Well then, how do we do it? This thesis suggests that when engaging in artistic expression, we reflect on our shared perceptual and cognitive faculties--"common sense," so to speak--and then construct stimuli to evoke experiences in our audience's brains. Drawing on ideas from computer graphics, cognitive science, and literary theory, I offer ways to think about images (Chandra et al., 2022) and stories (Chandra et al., 2023a,b) as objects to be designed with respect to a model of the audience. In particular, if we think of the audience's mind as solving inverse problems--perception as inverse rendering, action understanding as inverse planning--then we can think of expression as solving a kind of inverse inverse problem. I then show how to implement such "inverse inverse" methods computationally. Starting with classic Bayesian models of vision and social cognition, I present algorithms for optimizing over inference to create "adversarial examples" that evoke various desired inferences in those models. For example, we optimize images that are visual illusions (Chapter 1), and animations that tell surprising stories (Chapter 2). Because the Bayesian models capture human intuitions well (better than, say, typical neural network models), the optimized stimuli "transfer" to evoke similar experiences in humans. I demonstrate this with a variety of human subject studies.

Download or read book Photorealistic Rendering in Computer Graphics written by Pere Brunet and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photorealistic rendering strives to generate images from computer modeled scenes with an image quality as close to real life as possible. A major issue in rendering is simulation of local and global light reflection in a scene. Both ray tracing and radiosity algorithms capture only some of the possible light reflection phenomena. Recently developed two-pass algorithms combine the ray tracing and radiosity approaches and are able to capture the whole range of light reflection. This book is a collection of papers discussing the latest developments, including a new range of improvements, in stochastic sampling strategies, radiosity form factor calculation, and parallel processing for ray tracing and radiosity. A number of papers on rendering applications in interior design, lighting design, and remote sensing conclude the volume. The contributions are revised versions of papers originally presented at the Second Eurographics Workshop on Rendering, held in Barcelona, Spain, in May 1991. The book fully reflects the state of the art in rendering and presentsa wide variety of novel techniques. It will interest researchers and students in computer graphics, as well as designers who want to apply rendering techniques for realistic simulation in lighting design, interior design, and architecture.

Download or read book GPU based Techniques for Global Illumination Effects written by László Szirmay-Kalos and published by Morgan & Claypool Publishers. This book was released on 2008 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents techniques to render photo-realistic images by programming the Graphics Processing Unit (GPU). We discuss effects such as mirror reflections, refractions, caustics, diffuse or glossy indirect illumination, radiosity, single or multiple scattering in participating media, tone reproduction, glow, and depth of field. The book targets game developers, graphics programmers, and also students with some basic understanding of computer graphics algorithms, rendering APIs like Direct3D or OpenGL, and shader programming. In order to make the book self-contained, the most important concepts of local illumination and global illumination rendering, graphics hardware, and Direct3D/HLSL programming are reviewed in the first chapters. After these introductory chapters we warm up with simple methods including shadow and environment mapping, then we move on toward advanced concepts aiming at global illumination rendering. Since it would have been impossible to give a rigorous review of all approaches proposed in this field, we go into the details of just a few methods solving each particular global illumination effect. However, a short discussion of the state of the art and links to the bibliography are also provided to refer the interested reader to techniques that are not detailed in this book. The implementation of the selected methods is also presented in HLSL, and we discuss their observed performance, merits, and disadvantages. In the last chapter, we also review how these techniques can be integrated in an advanced game engine and present case studies of their exploitation in games. Having gone through this book, the reader will have an overview of the state of the art, will be able to apply and improve these techniques, and most importantly, will be capable of developing brand new GPU algorithms.

Available in PDF, EPUB and Kindle. Book excerpt: The book contains the proceedings of the 8th Eurographics Rendering Workshop, which took place from 16th to 18th June, 1997, in Saint Etienne, France. After a series of seven successful events the workshop is now well established as the major international forum in the field of rendering and illumination techniques. It brought together the experts of this field. Their recent research results are compiled in this proceedings together with many color images that demonstrate new ideas and techniques. This year we received a total of 63 submissions of which 28 were selected for the workshop after a period of careful reviewing and evaluation by the 27 mem bers of the international program committee. The quality of the submissions was again very high and, unfortunately, many interesting papers had to be rejected. In addition to regular papers the program also contains two invited lectures by Shenchang Eric Chen (Live Picture) and Per Christensen (Mental Images). The papers in this proceedings contain new research results in the areas of Finite-Element and Monte-Carlo illumination algorithms, image-based render ing, outdoor and natural illumination, error metrics, perception, texture and color handling, data acquisition for rendering, and efficient use of hardware. While some contributions report results from more efficient or elegant algo rithms, others pursue new and experimental approaches to find better solutions to the open problems in rendering.

Download or read book Rendering Techniques 98 written by George Drettakis and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Some of the best current research on realistic rendering is included in this volume. It emphasizes the current "hot topics” in this field: image based rendering, and efficient local and global-illumination calculations. In the first of these areas, there are several contributions on real-world model acquisition and display, on using image-based techniques for illumination and on efficient ways to parameterize and compress images or light fields, as well as on clever uses of texture and compositing hardware to achieve image warping and 3D surface textures. In global and local illumination, there are contributions on extending the techniques beyond diffuse reflections, to include specular and more general angle dependent reflection functions, on efficiently representing and approximating these reflection functions, on representing light sources and on approximating visibility and shadows. Finally, there are two contributions on how to use knowledge about human perception to concentrate the work of accurate rendering only where it will be noticed, and a survey of computer graphics techniques used in the production of a feature length computer-animated film with full 3D characters.

Download or read book High Fidelity Haptic Rendering written by Miguel A. Otaduy and published by Morgan & Claypool Publishers. This book was released on 2006-12-01 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The human haptic system, among all senses, provides unique and bidirectional communication between humans and their physical environment. Yet, to date, most human-computer interactive systems have focused primarily on the graphical rendering of visual information and, to a lesser extent, on the display of auditory information. Extending the frontier of visual computing, haptic interfaces, or force feedback devices, have the potential to increase the quality of human-computer interaction by accommodating the sense of touch. They provide an attractive augmentation to visual display and enhance the level of understanding of complex data sets. They have been effectively used for a number of applications including molecular docking, manipulation of nano-materials, surgical training, virtual prototyping, and digital sculpting. Compared with visual and auditory display, haptic rendering has extremely demanding computational requirements. In order to maintain a stable system while displaying smooth and realistic forces and torques, high haptic update rates in the range of 500-1000 Hz or more are typically used. Haptics present many new challenges to researchers and developers in computer graphics and interactive techniques. Some of the critical issues include the development of novel data structures to encode shape and material properties, as well as new techniques for geometry processing, data analysis, physical modeling, and haptic visualization. This synthesis examines some of the latest developments on haptic rendering, while looking forward to exciting future research in this area. It presents novel haptic rendering algorithms that take advantage of the human haptic sensory modality. Specifically it discusses different rendering techniques for various geometric representations (e.g. point-based, polygonal, multiresolution, distance fields, etc), as well as textured surfaces. It also shows how psychophysics of touch can provide the foundational design guidelines for developing perceptually driven force models and concludes with possible applications and issues to consider in future algorithmic design, validating rendering techniques, and evaluating haptic interfaces.
