This project was born from the desire to explore and learn about the marching cubes algoritm, as presented by William E. Lorensen and Harvey E. Cline in their paper: Marching Cubes: A High Resolution 3D Surface Construction Algorithm. Computer Graphics, 21 (4): 163-169, July 1987. Implementation results are presented in real-time using the UnityEngine (https://unity.com/) rendering pipeline and C# scripting API.
The root of the repository may be loaded as a standalone Unity project directory, complete with a SampleScene scene file within which users may wish to customize the parameters of different implicit shapes ( or constant density surfaces as denoted by the algorithm developers ) in order to alter the visual outcome statically or during application lifetime.
In addition, the code itself exposes relevant MonoBehaviour component implementations to be controlled at runtime and contains some basic optimization techniques targeted at increasing general rendering speed.
