Journal ArticleDOI
The Design of an Inexpensive Very High Resolution Scan Camera System
Shuzhen Wang,Wolfgang Heidrich +1 more
TL;DR: This paper describes a system for transforming an off‐the‐shelf flatbed scanner into a $200 scan backend for large format cameras, and shows that actual optical resolutions close to the theoretical maximum, and that color reproduction is comparable to commercial camera systems.
Journal ArticleDOI
A Biologically-Parameterized Feather Model
Lisa Streit,Wolfgang Heidrich +1 more
TL;DR: This paper defines the structure of individual feathers using a parameterization based on biological structure and substructures of actual feathers to generate a large variety of feathers at multiple levels of detail and provide an initial step to semi‐automatically generating a wide range of feather coats.
Book
Real-Time Shading
Marc Olano,Kurt Akeley,John Hart,Wolfgang Heidrich,Michael McCool,Jason L. Mitchell,Randi Rost +6 more
TL;DR: This course has been redesigned to address today's real-time shading capabilities and to provide more practical information for practitioners.
Journal ArticleDOI
A simple layered RGB BRDF model
Xavier Granier,Wolfgang Heidrich +1 more
TL;DR: This article presents a model for both specular and diffuse reflection, with a simple RGB BRDF model, and experiments with a general approach to create similar and convincing effects.
Journal ArticleDOI
Unsharp Masking, Countershading and Halos: Enhancements or Artifacts?
TL;DR: This paper investigates the perception of countershading in the context of a novel mask‐based contrast enhancement algorithm and analyzes the circumstances under which the resulting profiles turn from image enhancement to artifact for a range of parameters and viewing conditions.
