# Realsoft 3D

Realsoft 3D is a modeling and raytracing application created by Realsoft Graphics Oy. Originally called Real 3D, it was developed for the Amiga computer and later also for Linux, Irix, Mac OS X, and Microsoft Windows.
It was initially written in 1983 on Commodore 64 by two Finnish brothers, Juha and Vesa Meskanen. The development of Real 3D was really started in 1985, as Juha Meskanen started his studies at the Lahti University of Applied Sciences, Finland. Juha's brother Vesa joined the development and abandoned his university career to start the Realsoft company in 1989.

## Versions history
### Real 3D v1

The first commercial Real 3D version was released on Amiga.
It used IFF REAL for its objects.
It featured constructive solid geometry, support for smooth curved quadric surfaces and a ray-tracer for photo realistic rendering.
1.2 was released in 1990, was already distributed in several European countries.
1.3 was released early 1991.
1.4 was released in December 1991. It was the last version derived from the original Real3D design.
Despite small version number increments, v1, v1.2 and v 1.3 were all major releases, with new manuals and packaging.

### Real 3D v2

It was released in 1993.
Version 2 was redesigned with a new source code base. It introduced groundbreaking features - booleans, CSG primitives, b-spline curves, physically based animation simulation, morph-based animation techniques and phenomenal rendered output. It took full advantage of the multi-tasking abilities of the Amiga - allowing the user to continue editing a scene on another window while it rendered.
Microsoft Windows version was released in 1994.

### Real 3D v3

Version 3.5 was released in 1996.
It was the last version based on v2 architecture. Realsoft had started a new major development project around 1994. The project involved a complete software rewrite, new object-oriented source code, platform independent design, modularity, and adoption of several other state-of–art development methods.
Amiga version 3.5, which is also the last version for this system, is now freely available by AmiKit.
