Free/Open Source Software
What is open source software?
Open source software is software whose source code is available for modification or enhancement by anyone.
"Source code" is the part of software that most computer users don't ever see; it's the code computer programmers can manipulate to change how a piece of software—a "program" or "application"—works. Programmers who have access to a computer program's source code can improve that program by adding features to it or fixing parts that don't always work correctly.
Some of the major CAD software companies offer FREE cut down versions of their flagship solutions theese can be a great alternative for those just needing the basics of CAD often 2D only they can save a company spending thousands on complex software
Some of our favourites and best solutions are described below with links to their host sites
Sculptris is a professional yet free 3D modelling program that is made by one industry 3D expert, Pixologic. You can use it to easily design your own version of a troll, dragon, or even Godzilla itself through their rich sculpting toolset. If you’re bad at playing around the geometry and polygons to create your own surface, worry not, because Sculptris surface contains countless of triangles that are automatically built into your 3D model surface.
Blender is the free and open source 3D creation suite. It supports the entirety of the 3D pipeline—modelling, rigging, animation, simulation, rendering, compositing and motion tracking, even video editing and game creation.
