This is a program that uses assimp to convert different 3d model formats to file format that amalgine can read (.a3d).
To see a list of supported file formats, see https://github.com/assimp/assimp#supported-file-formats (this is for the latest version of assimp).

# Amalgine 3D model file format (.a3d)
.a3d is a binary file format. All types are stored in little endian format. Any type with a * is optional.

|Type   |Description                                                                          |
|-------|-------------------------------------------------------------------------------------|
|uint   |The magic number, the value will always be 0x036144AF.                               |
|uint   |Version of the file format. This is backwards compatible but not forwards compatible.|
|mesh[] |The mesh data.                                                                       |

|uint       |The number of vertices, normals and optionally texture coordinates.                             |
|vec3f[]    |A list of vertices.                                                                             |

|uint       |1 if the model has texture coordinates, otherwise 0.                                            |
|vec2f[]*   |A list of texture coordinates. The number of texture coordinates matches the number of vertices.|
|uint       |The number of faces.                                                                            |

|uint       |1 if the model has materials, otherwise 0.                                                      |
|material[3]|The material data. This is a list of [diffuse, specular, ambient] materials.                    |
