3D Construction Kit (US, Canada and Israel release title: Virtual Reality Studio), also known as 3D Virtual Studio, is a utility for creating 3D worlds in Freescape. Developed by Incentive Software and published by Domark, it was released in 1991 on multiple platforms. The game originally retailed for £24.99 for the 8-bit version, and £49.99 for 16-bit version, in the United Kingdom. A sequel, 3D Construction Kit II, was released in 1992, but only available on Amiga, Atari ST or IBM PC (DOS).
3D Construction Kit was originally released on the ZX Spectrum in early 1991. Later the same year it was adapted for numerous other platforms, including versions for the Amstrad CPC, Atari ST, PC as well as the Commodore 64 and Commodore 128. A version for the Amiga was released on June 1, 1991 and proved relatively popular with computer users. The Acorn Archimedes was released in January 1992. The different versions of the game varied slightly in their user interface, which was progressively improved with each successive release. An unofficial version for the Commodore Plus 4 was released in 1992.
The 3D Construction Kit packages came with a 30-minute video tape, featuring an introduction and a tutorial presented by Ian Andrew, the original designer of the Freescape system.
3D Construction Kit is available in five language editions: English, German, French, Spanish and Italian.
