Programming real time graphics has been made more efficient by introducing high level shading languages such as Cg and GLSL. Writing shader programs can be redundant since the same functions appear in many shaders. This article suggests a method to combine single functions and create compound shaders in runtime. Redundancy is avoided by dividing programs… (More)
In this paper, we describe an improved method for visualization of thermographic data in the paper and pulp process industry. We present an application that allows process operators to freely choose how absolute temperatures and time varying changes of thermographic scans should be mapped to colors and/or 3D shapes. Of the possible combinations, we selected… (More)
With tomographic in situ visualization we present a novel approach to interactive data visualization and exploration. This visualization concept is useful for presentation of spatially co-located information that is normally not visible to the human's eye. The tomographic in situ display allows for interactive cutting through data in space by using a… (More)
Figure 1: Reconstructed surfaces from two scans of the same door and exaggerated, color coded difference. Abstract We present a method for rapid GPU-assisted surface reconstruction from range scanner data producing meshes suitable for visualiza-tion and analysis of very slow-moving objects from multiple scans of the same area.
Maximum normal Proposed method Figure 1: Comparison between diffuse light calculated with maximum normal and proposed method for two directions of anisotropy. Abstract Cloth, hair, brushed metal, and other surfaces with small, regular surface features exhibit anisotropic reflectance properties for which common isotropic shading methods are not suited.… (More)
