Geometry Worksheets

TopDrawer makes it easy to produce beautifully typeset Euclidean geometry diagrams.

SciGraphica is a scientific data visualization and analysis application, supplying many of the basic plotting features for 2D and 3D charts. It features opening several worksheets and plots to work with at the same time and PS output.

It is implemented in JavaScript, using the jQuery and Prototype framewroks, and uses image formats like SVG and VML. Key features "JSXGraph": - Euclidean Geometry: Points, lines, circles, intersections, perpendicular lines, angles - Curve plotting: Graphs, parametric curves, polar curves, data...

This program calculates view factors and radiative heat transfers between two or many surfaces. Surfaces must be polygons or circles. For each surface, you must enter the parameters relative to their geometry, the emissivity, either the temperature or the radiative balance. For each surface, the...
