What is it about
Keywords: Non-Euclidean geometry, geometry of curves, Visualization
GFViewer is a geometric tool for creating and manipulating objects in a non-Euclidean geometry, called GF geometry, which is comprised of lines which satisfy the first four but not necessarily the fifth Euclidean postulates. This tool allows for the visualization of geometric objects as well as the result of algorithms implemented therein. This system is currently under development at the Institute of Computing at UNICAMP (State University of Campinas).
Key Benefits
 |
real-time drawing of GF objects (with rubberband motion); |
|
display of the same objects under alternate families of curves; |
|
a small (but growing) set of geometric algorithms. |
