Abstract: We present our method of real-time rendering of grid-structured data The method uses bicubic spline interpolation running on common current graphics hardware to map the values to a texture It allows us to render isolines of the visualized data and dynamically change the visualization parameters We have implemented the method and incorporated it into a system of real-time simulation and visualization of combustion processes in pulverized coal boilers We have compared the visual quality of produced images with the previously used visualization methods

A class of local interpolating splines
Edwin Catmull,Raphael Rom +1 more
TL;DR: In this article, the authors discuss a general class of splines having some useful characteristics for design purposes, including differentiability, degree of polynomials to be blended, the localness of the spline, which determines whether it interpolates or approximates, and the type of blending function.

The Interface Of Cognitive And Psychophysical Research In Cartography
TL;DR: In this paper, the authors argue that there is a need in cartographic research for all three kinds of experiments: the primarily-psychophysical, the primarily cognitive, and the integrated psychophysical/cognitive.

Efficient methods for Isoline extraction from a TIN
TL;DR: A data structure is presented to store a triangulated irregular network digital elevation model, from which isolines can be extracted very efficiently, and in all three cases, the required data structure has only linear size.

Fast generation and display of iso-surface wireframes
TL;DR: The method is efficient enough to form the basis for an interactive software system for visualizing iso-surfaces and supports efficient generation and display of the iso-surface wireframe corresponding to any selected threshold value.
