Geometria ofrece una interfaz gráfica para crear y resolver problemas de geometría en 3D. Se puede emplear y distribuir libremente bajo licencia GPL.
Con Geometria, se pueden trazar y medir segmentos y ángulos, medir áreas y volúmenes, transformar, recortar y unir figuras. Las figuras pueden girar y rotar con la facilidad con que lo haríamos con nuestras propias manos.
Have you ever come across an oddly stretched image on the sidewalk, only to find that it looks remarkably realistic if you stand in exactly the right spot? These sidewalk illusions employ a technique called anamorphosis - a special case of perspective art where artists represent 3D views on 2D surfaces. So how is it done? Fumiko Futamura traces the history and mathematics of perspective.
When you're working on a problem with lots of numbers, as in economics, cryptography or 3D graphics, it helps to organize those numbers into a grid, or matrix. Bill Shillito shows us how to work with matrices, with tips for adding, subtracting and multiplying (but not dividing!).
