Images incorporating microstructures

Roger Hersch, Patrick Emmel

A method of generating an image incorporating a microstructure includes the steps of obtaining an original image, generating a microstructure, and rendering a region or the whole said original image with said microstructure. The operation of generating the ...

Precision Isosurface Rendering of 3-D Image Data

Michaël Unser, Philippe Thévenaz

We address the task of rendering by ray tracing the isosurface of a high-quality continuous model of volumetric discrete and regular data. Based on first principles, we identify the quadratic B-spline as the best model for our purpose. The nonnegativity of ...

Splines and wavelets for image warping and projection

Stefan Horbelt

This thesis investigates advanced signal processing concepts and their application to geometric processing and transformations of images and volumes. In the first part, we discuss the class of transformations that project volume data onto a plane using par ...

High-Quality Isosurface Rendering with Exact Gradient

Michaël Unser, Philippe Thévenaz

We address the task of rendering by ray tracing the isosurface of a high-quality continuous spline model of volumetric discrete and regular data. By expressing the spline model as a sum of nonnegative B-splines, we are able to confine the potential locatio ...

Real-time display of virtual humans: levels of details and impostors

Daniel Thalmann, Ronan Boulic, Amaury Aubel

Rendering and animating in real-time a multitude of articulated characters presents a real challenge, and few hardware systems are up to the task. Up to now, little research has been conducted to tackle the issue of real-time rendering of numerous virtual ...

Lowering the cost of virtual human rendering with structured animated impostors

Daniel Thalmann, Ronan Boulic, Amaury Aubel

We present an image-based rendering technique to represent virtual humans in real-time. Though we deal only with virtual humans, the concept can be applied to any articulated character. Our technique is termed animated impostors because it extends the noti ...

Animated impostors for real-time display of numerous virtual humans

Daniel Thalmann, Ronan Boulic, Amaury Aubel

Rendering and animating a multitude of articulated characters in real-time presents a real challenge, and few hardware systems are up to the task. Up to now, little research has been conducted to tackle the issue of real-time rendering of numerous virtual ...

Rendering real-world objects using view interpolation

Roger Hersch

Presents a new approach to rendering arbitrary views of real-world 3D objects of complex shapes. We propose to represent an object by a sparse set of corresponding 2D views, and to construct any other view as a combination of these reference views. We show ...

Rendering hair using pixel blending and shadow buffers

Daniel Thalmann

A technique is described for adding natural-looking hair to standard rendering algorithms. Using an explicit hair model, in which each individual hair is represented by a three-dimensional curve, the technique uses pixel blending combined with Z-buffer and ...

Efficient rendering of outline characters

Roger Hersch

Resolution-independent windowing systems and raster image processors require efficient and precise rendering of outline characters. Rendering of typographic outline characters involves outline grid fitting, outline scan conversion, and filling. For the pur ...
