# 3D Perlin noise using marching cubes algorithm 

![](https://raw.githubusercontent.com/mikhomak/Images/master/MarchinCubes/3D%20Perlin%20Noise.png)

## About:

This component allows you to generate 3D Perlin Noise mesh with collisions in runtime in unreal engine.    

![](https://github.com/mikhomak/Images/blob/master/MarchinCubes/gifPreview.gif)

## Requirements:

In order for this component to work you will need:

1. Unreal Engine 4 2.5 (2.6 is yet not supported by *RuntimeMeshComponent* so you need to use 2.6 or update *RuntimeMeshComponent* to 2.6)

2. [Runtime mesh component](https://github.com/TriAxis-Games/RuntimeMeshComponent) - In order to create a mesh ([Marketplace](https://www.unrealengine.com/marketplace/en-US/product/runtime-mesh-component))

3. [PerlinNoiseComponent](https://github.com/nialna/PerlinNoiseComponent) - In order to get noise values (This component comes bundled in this repo)

## Installation:

1.  Install the ***RuntimeMeshComponent***  

2.  Add ***libnoise*** library to your UE4 project. You can find how [in this repo](https://github.com/nialna/libnoise-UE4-ready) by [nialna](https://github.com/nialna). P.S. - in the git history of this repo you can find installed version of libnose. 

4.  Copy *PerlinNoiseComponent.h* and *PerlinNoiseComponent.cpp* to your `Source` folder. This component was made by [nialna](https://github.com/nialna), thanks a lot to her!

3.  Copy *MCubeComponent.h* and *MCubeComponent.cpp* to your `Source` folder. (You can also copy *MCubeActor.h* and *MCubeActor.cpp* which is an Actor example)

4.  Add `UMcubeComponent, URuntimeMeshComponentStatic` and `UPerlinNoiseComponent` to your actor. Set `Noise` and `RuntimeMesh` variables for `UMcubeComponent`.

5.  Call `GenerateMarchingCubeMesh()` of `UMcubeComponent` to generate the mesh!

## FAQ:

**1) Does the mesh have collisions?**   

YES, but you can disable them in *MCubeComponent.cpp* `    RuntimeMesh->CreateSectionFromComponents(0,

                                             0,

                                             0,

                                             Vertices,

                                             Triangles,

                                             Normals,

                                             UV,

                                             VertexColors,

                                             Tangents,

                                             ERuntimeMeshUpdateFrequency::Infrequent,

                                             true);` by setting the last argument to `false`.

**2) Can you use it as a Terrain?**   

Yeap, but I recomend you for this purpouse to use [Voxel plugin](https://www.unrealengine.com/marketplace/en-US/product/voxel-plugin-free) which is cool as shit
