Developed with Unity 5.6, might work on older versions as well. No guarantee tho. Requires DX11 hardware. Not honestly sure about mobile phones, but my guess is it won't work. Feel free to correct me.
The generating of density field is done on CPU, but for demonstration purposes it should be enough. You will probably want to modify the MarchingCubes.DensityTexture from Texture3D to RenderTexture in a real application.
ProceduralGeometry shader used for drawing the MC is barebone and contains only diffuse lightning; replace it with a custom one, modified to your liking. :)
Any pull requests and issues are welcome.
Implementing this would not be possible without:
- The algorithm and lookup tables by Paul Bourke http://paulbourke.net/geometry/polygonise/
- The gradient normals calculation http://www.angelfire.com/linux/myp/MCAdvanced/MCImproved.html
- Vilém Otte https://github.com/Zgragselus, and his debugging/troubleshooting skills
