Cabri 3D Interactive Geometry
Explore Solid Geometry with Cabri 3D

Cabri 3D is interactive solid geometry software. Using Cabri 3D, in a few clicks, you can construct and manipulate the following solid geometry objects:-

“It promises to revolutionise computer assisted visualisation and reasoning in 3D geometry in much the same way as the earlier ‘dynamic geometry software’ (DGS) has done for plane geometry.”
- Professor Adrian Oldknow

Dynamically transform your construction to reveal relationships between the elements.

Clarify and organise your construction using the numerous graphic attributes available (colours, textures, styles).

Freely move the viewpoint around your construction, and simultaneously display any number of projections (from a choice of over 15 standard projections).

Organise these views on one or more pages, adding comments (rich text).

Print or capture document pages at high resolution.Export your documents as interactively manipulable figures for inclusion in Windows applications and web pages (free Windows plugin).

Cabri 3D is a completely new product and is available separately from the 2D ‘Cabri-Geometry II Plus’. Download Cabri 3D Version 1 leaflet.

Onecast New! -

OneCast identified and exploited this gap. By reverse-engineering the protocol used for Xbox-to-Windows streaming, the developers created a standalone client that allowed Mac users to connect to their Xbox One or Xbox Series X/S consoles. This was not merely a novelty; it was a functional solution for a demographic ignored by the first-party manufacturer. It highlighted a disconnect between hardware manufacturers and consumer desire: while corporations often use exclusive software to drive hardware sales (i.e., buying a PC to use Xbox features), third-party developers like OneCast prioritized user accessibility over ecosystem loyalty.

Despite its ingenuity, OneCast has never been an official Microsoft product, and this status imposes inherent risks. Apple’s App Store guidelines have historically restricted applications that function as remote desktop or gaming clients unless they comply with strict rules. OneCast circumvented some hurdles by initially distributing via direct download for Mac and TestFlight for iOS, later securing a permanent App Store presence. More critically, Microsoft occasionally updates its Xbox authentication protocols or streaming APIs, which can temporarily break third-party clients. OneCast’s developer has been diligent about updates, but each patch reminds users that the application exists at the pleasure of Microsoft’s undocumented goodwill. onecast

A one-cast production is the ultimate test of versatility and narrative focus . It strips away the spectacle of a large ensemble to focus on the raw connection between the performer and the audience. OneCast identified and exploited this gap

Construct and manipulate

While constructing, already built objects can be constantly manipulated, and the projection of the current view updated. Object selection can be made in any view. The implicit mechanism of object creation considerably simplifies the construction of the figures. A point of intersection between a line and a plan in a construction can thus be used without having to create in advance.
Many graphic attributes (colour, size, texture) can be applied to objects to create even more attractive and comprehensible figures.

CabriML and Web figures

The Cabri 3D files format is based on the XML standard (CabriML), so that any user may understand and modify Cabri 3D files. Combined with the internal use of the Unicode standard for the representation of the characters, Cabri 3D can be used to create and read figures in all languages.
The Cabri 3D plug-in allows dynamic geometry figures to be published on the Internet, and also in other word processing documents.

Recommended configuration. Windows XP (but works with 98 or higher except NT) or Mac OS X 10.3, 800MHz, RAM 256 Mb, graphic adapter NVidia GeForce 2 or ATI Radeon 7000.

BETT Award 2007 Maths

Becta BETT Awards 2007 Winner: " Cabri 3D is a 3D visualisation tool that allows secondary school students to explore the properties of 3D space and solid geometry with mathematical rigour. The product is closely aligned to the shape, space and measures aspect of the Maths National Curriculum. Students can quickly create and manipulate shapes in creative ways that would be impossible to replicate with solid objects. "
