How can I implement the marching cubes algorithm in Unity? Or is there a better solution for smoothing?
Any code/examples/documents are helpful, preferably JS.
as you know marching cubes is an algorithm for generating polygonal meshes. you should first implement the algorithm which i think you might not be able to find here in the community easily and then add those polygons to a vertext array and turn it into a mesh.
basically you should create a mesh of type Mesh class in unity and then add the generated vertecies to it. then create a trianglestrip from them and render them easily.
there are tutorials for procedural mesh generation in unity’s example projects and other websites that might be helpful.
finding a code in c++ for marchingcubes is not that hard and turning the code into C# or js is easy.
