split merge mesh

You can split all meshes of a 3D scene into several sub-meshes. Likewise, you can merge multiple meshes into a single mesh programmatically using C#. This article covers the splitting and merging of 3D meshes in different scenarios:

3D Scene Meshes Splitter or Merger – C# API Installation

Aspose.3D for .NET API can be used to split or merge 3D meshes programmatically using C#. You can configure the API by installing it from the Downloads section, or with the below NuGet installation command:

PM> Install-Package Aspose.3D

Split Meshes of a Scene Per Material Programmatically using C#

A 3D file like the FBX format can contain several meshes of a scene. You can split all meshes into several sub meshes per material if the mesh has not been assigned a single material. Please follow the steps below for splitting meshes of a scene per material:

  1. Load input 3D file.
  2. Split all meshes with the SplitMesh method.
  3. Save output file with the splitted meshes.

The following code shows how to split meshes of a scene per material programmatically using C#:

Split a Mesh by a Specific Material Programmatically using C#

You can split a mesh by manually specifying the material. In this way, you can create several objects containing only one material. For demonstration purposes, the below code creates a mesh of a box with 6 planes. Then you will split a primitive mesh by manually specifying the material using the following steps:

  1. Create a mesh of a box with six planes.
  2. Secondly, create a material element and specify indexes for each plane.
  3. Split the Mesh using SplitMeshPolicy enumeration.

The code below explains how to split a mesh by specific material programmatically using C#:

Merge Meshes in a 3D file into a Single Mesh Programmatically in C#

You can merge different meshes into a single valid mesh with the below steps:

  1. Load input 3D scene file.
  2. Merge all meshes.
  3. Finally, encode the merged mesh.

The following code elaborates how to merge meshes into a single mesh programmatically using C#:
