Real-Time Rendering of Rough Refraction
Found in: IEEE Transactions on Visualization and Computer Graphics
By Charles de Rousiers,Adrien Bousseau,Kartic Subr,Nicolas Holzschuch,Ravi Ramamoorthi
Issue Date:October 2012
pp. 1591-1602
We present an algorithm to render objects made of transparent materials with rough surfaces in real-time, under all-frequency distant illumination. Rough surfaces cause wide scattering as light enters and exits objects, which significantly complicates the ...
 
The drawing assistant: automated drawing guidance and feedback from photographs
Found in: Proceedings of the 26th annual ACM symposium on User interface software and technology (UIST '13)
By Adrien Bousseau, Emmanuel Iarussi, Theophanis Tsandilas
Issue Date:October 2013
pp. 183-192
We present an interactive drawing tool that provides automated guidance over model photographs to help people practice traditional drawing-by-observation techniques. The drawing literature describes a number of techniques to %support this task and help peo...
     
Diffusion curves: a vector representation for smooth-shaded images
Found in: Communications of the ACM
By Adrien Bousseau, Alexandrina Orzan, David Salesin, Holger Winnemöller, Joëlle Thollot, Pascal Barla
Issue Date:July 2013
pp. 101-108
We describe a new vector-based primitive for creating smooth-shaded images, called the diffusion curve. A diffusion curve partitions the space through which it is drawn, defining different colors on either side. These colors may vary smoothly along the cur...
     
Depicting stylized materials with vector shade trees
Found in: ACM Transactions on Graphics (TOG)
By Adrien Bousseau, George Drettakis, Jorge Lopez-Moreno, Maneesh Agrawala, Stefan Popov
Issue Date:July 2013
pp. 1-10
Vector graphics represent images with compact, editable and scalable primitives. Skillful vector artists employ these primitives to produce vivid depictions of material appearance and lighting. However, such stylized imagery often requires building complex...
     
Gloss perception in painterly and cartoon rendering
Found in: ACM Transactions on Graphics (TOG)
By Adrien Bousseau, Frédo Durand, James P. O'shea, Maneesh Agrawala, Ravi Ramamoorthi
Issue Date:April 2013
pp. 1-13
Depictions with traditional media such as painting and drawing represent scene content in a stylized manner. It is unclear, however, how well stylized images depict scene properties like shape, material, and lighting. In this article, we describe the first...
     
Coherent intrinsic images from photo collections
Found in: ACM Transactions on Graphics (TOG)
By Adrien Bousseau, Frédo Durand, George Drettakis, Pierre-Yves Laffont, Sylvain Paris
Issue Date:November 2012
pp. 1-11
An intrinsic image is a decomposition of a photo into an illumination layer and a reflectance layer, which enables powerful editing such as the alteration of an object's material independently of its illumination. However, decomposing a single photo is hig...
     
Rich intrinsic image decomposition of outdoor scenes from multiple views
Found in: ACM SIGGRAPH 2012 Talks (SIGGRAPH '12)
By Adrien Bousseau, George Drettakis, Pierre-Yves Laffont
Issue Date:August 2012
pp. 1-1
Intrinsic images aim at separating an image into reflectance and illumination layers to facilitate analysis or manipulation. Most successful methods rely on user indications [Bousseau et al. 2009], precise geometry, or need multiple images from the same vi...

CrossShade: shading concept sketches using cross-section curves
Found in: ACM Transactions on Graphics (TOG)
By Adrien Bousseau, Alla Sheffer, Cloud Shao, Karan Singh
Issue Date:July 2012
pp. 1-11
We facilitate the creation of 3D-looking shaded production drawings from concept sketches. The key to our approach is a class of commonly used construction curves known as cross-sections, that function as an aid to both sketch creation and viewer understan...
     
User-assisted intrinsic images
Found in: ACM SIGGRAPH Asia 2009 papers (SIGGRAPH Asia '09)
By Adrien Bousseau, Fredo Durand, Sylvain Paris
Issue Date:December 2009
pp. 1-6
For many computational photography applications, the lighting and materials in the scene are critical pieces of information. We seek to obtain intrinsic images, which decompose a photo into the product of an illumination component that represents lighting ...
     
Non-linear aperture for stylized depth of field
Found in: SIGGRAPH 2009: Talks (SIGGRAPH '09)
By Adrien Bousseau
Issue Date:August 2009
pp. 1-1
We introduce in this paper non-linear apertures that produce stylized depth of field from lightfield data. A non linear aperture is similar in spirit to the conventional aperture of a camera, except that it replaces the blur of shallow depth of field by a ...
     
Diffusion curves: a vector representation for smooth-shaded images
Found in: ACM Transactions on Graphics (TOG)
By Adrien Bousseau, Alexandrina Orzan, David Salesin, Holger Winnemoller, Joelle Thollot, Pascal Barla
Issue Date:August 2008
pp. 1-49
We describe a new vector-based primitive for creating smooth-shaded images, called the diffusion curve. A diffusion curve partitions the space through which it is drawn, defining different colors on either side. These colors may vary smoothly along the cur...
