Surface-Curve Graphical Intersection Tools and Primitives for Data Visualization, Tabular Data, and Advanced Spreadsheets

摘要

Graphical tools and primitives are provided for interactively intersecting at least one graphical surface and curve in a spreadsheet or visualization to produce intersection data. Applications include simple business analysis as well as advanced engineering and science, and provide numerical solution for simultaneous spatially-manipulated interactive equations. Visualizations of two-dimensional surfaces are rendered from provided data according to position, orientation, and viewpoint, some or all of which can be controlled by a user interface so as to create or control the intersection of surfaces. The provided data can be from an electronic spreadsheet, and the overall visualization can be displayed together with the display an electronic spreadsheet or other tabular data representation. Visually rendered surfaces can comprise symbols, colors, textures, or glyphs representing data, and virtual illumination. Intersection data corresponding to the mathematical intersection of the surfaces is computed and provided to further computation. Intersection computation can comprise interpolation and resampling.
