Space geometry

Three-dimensional solid geometry is part of mathematics teaching programs starting early on with shape recognition, and developed through high school, college and university.

Many Cabri Geometry II Plus users already construct 3D figures, often using a lot of patience and tricks since the software works essentially in the plane (2D).

Cabri 3D brings the missing dimension, at both mathematical engine and display level.

3D space models our world perfectly and manipulating 3D objects such as planes, solids, cylinders, and spheres is both a real and attractive activity. Cabri 3D uses OpenGL® display technology to make the most of 3D graphics cards marketed for the last several years. Images obtained are far from the ‘wire’ model used conventionally, and their animation is fluid.

Due to previous lack of appropriate software and the difficulty in visualising objects in space, 3D geometry is a partially explored field. In this context, Cabri 3D provides teachers and researchers a valuable tool to explore and discover new properties, new theorems yet to be unveiled. For example, see Professor Adrian Oldknow's fascinating Cabri 3D pages and tutorials produced for the Mathematical Association.

A Cabri 3D document consists of a set of pages, and one or more views are positioned on each page displaying the figure through a different projection. In each view, a projection can be free and easy to manipulate consistently, even while constructing.

A view can be copied on the clipboard as a high resolution image, and be used as an illustration in other documents. This process provides results of much better quality than a screen capture. The print reproduces the set of pages and views, and uses the 3D acceleration features/capabilities of modern graphics cards; this enables the creation of high quality documents with a high degree of accuracy.
