Purkinje Images: Conveying Different Content for Different Luminance Adaptations in a Single Image
(Copyright © 2015 The Eurographics Association and John Wiley & Sons Ltd., 2015)
Providing multiple meanings in a single piece of art has always been intriguing to both artists and observers. We present Purkinje images, which have different interpretations depending on the luminance adaptation of the ...
Making Imperfect Shadow Maps View‐Adaptive: High‐Quality Global Illumination in Large Dynamic Scenes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
We propose an algorithm to compute interactive indirect illumination in dynamic scenes containing millions of triangles. It makes use of virtual point lights (VPL) to compute bounced illumination and a point‐based scene ...
Homunculus Warping: Conveying Importance Using Self-intersection-free Non-homogeneous Mesh Deformation
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Size matters. Human perception most naturally relates relative extent, area or volume to importance, nearness and weight. Reversely, conveying importance of something by depicting it at a different size is a classic artistic ...
Texture Stationarization: Turning Photos into Tileable Textures
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Texture synthesis has grown into a mature field in computer graphics, allowing the synthesis of naturalistic textures and images from photographic exemplars. Surprisingly little work, however, has been dedicated to ...
Practical Capture and Reproduction of Phosphorescent Appearance
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
This paper proposes a pipeline to accurately acquire, efficiently reproduce and intuitively manipulate phosphorescent appearance. In contrast to common appearance models, a model of phosphorescence needs to account for ...
Decomposing Single Images for Layered Photo Retouching
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Photographers routinely compose multiple manipulated photos of the same scene into a single image, producing a fidelity difficult to achieve using any individual photo. Alternately, 3D artists set up rendering systems to ...
Minimal Warping: Planning Incremental Novel-view Synthesis
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Observing that many visual effects (depth-of-field, motion blur, soft shadows, spectral effects) and several sampling modalities (time, stereo or light fields) can be expressed as a sum of many pinhole camera images, we ...
Deep Shading: Convolutional Neural Networks for Screen Space Shading
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
In computer vision, convolutional neural networks (CNNs) achieve unprecedented performance for inverse problems where RGB pixel appearance is mapped to attributes such as positions, normals or reflectance. In computer ...
Single-image Tomography: 3D Volumes from 2D Cranial X-Rays
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
As many different 3D volumes could produce the same 2D x-ray image, inverting this process is challenging. We show that recent deep learning-based convolutional neural networks can solve this task. As the main challenge ...
The State of the Art in Interactive Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
The interaction of light and matter in the world surrounding us is of striking complexity and beauty. Since the very beginning of computer graphics, adequate modelling of these processes and efficient computation is an ...
