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 | |-------|-------------------------------------------------------------------------------------| |u32 |The magic number, the value will always be 0x036144AF. | |u32 |Version of the file format. This is backwards compatible but not forwards compatible.| |mesh[] |The mesh data. |

mesh:

|Type |Description | |-----------|------------------------------------------------------------------------------------------------| |u32 |The number of vertices, normals and optionally texture coordinates. | |vec3f[] |A list of vertices. | |vec3f[] |A list of normals. | |u32 |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.| |u32 |The number of faces. | |face[] |The face indices. | |u32 |1 if the model has materials, otherwise 0. | |material[3]|The material data. This is a list of [diffuse, specular, ambient] materials. |

vec2f:

|Type |Description | |-----|----------------| |float|The x coordiate.| |float|The y coordiate.|

vec3f:

|Type |Description | |-----|----------------| |float|The x coordiate.| |float|The y coordiate.| |float|The z coordiate.|

face:

|Type|Description | |----|-----------------| |u32 |The first index. | |u32 |The second index.| |u32 |The third index. |

material:

|Type |Description | |------|---------------------------------------------------------------------------| |u32 |The number of textures. | |char[]|The filepaths to the textures (relative). This is a null-terminated string.|
