Import Data Structures
You should upgrade to
This section describes basic metadata structures used to represent various scene objects, such as cameras, lights, meshes, etc.
ImportAnimation Structure#
This data structure contains metadata on an imported animation and has the following set of properties:

| max_time | End time of the animation in seconds. |
struct ImportAnimation
{
String name;
float min_time;
float max_time;
};ImportCamera Structure#
This data structure contains metadata on an imported camera and has the following set of properties:
| node | Scene node to which the camera is attached as an attribute. |
| data | Camera metadata. |
struct ImportCamera
{
ImportNode *node = nullptr;
UserData *data = nullptr;
};ImportLight Structure#
This data structure contains metadata on an imported light and has the following set of properties:
| node | Scene node to which the light is attached as an attribute. |
| data | Light metadata. |
struct ImportLight
{
ImportNode *node = nullptr;
UserData *data = nullptr;
};ImportMesh Structure#
This data structure contains metadata on an imported mesh and has the following set of properties:
| name | Mesh name. |
| filepath | Path to the mesh file. |
| animation_filepath | Path to the animation file. |
| has_animations | Flag indicating whether the mesh has aminations or not. |
| nodes | List of nodes to which the mesh is attached as an attribute. |
| geometries | Mesh geometry. A vector of ImportGeometry |
struct ImportMesh
{
String name;
String filepath;
String animation_filepath;
bool has_animations = false;
Vector<ImportNode *> nodes;
Vector<ImportGeometry> geometries;
};ImportMaterial Structure#
This data structure contains metadata on an imported material and has the following set of properties:
| name | Material name. |
| filepath | Path to the material's *.mat file. |
| data | Material metadata. |
struct ImportMaterial
{
String name;
String filepath;
UserData *data = nullptr;
};ImportNode Structure#
This data structure contains metadata on an imported node and has the following set of properties:
| name | Scene node name. |
| filepath | Path to the node file. |
| parent | Parent node. |
| children | List of all node children. |
| mesh | Mesh node attribute. ImportMesh structure pointer if a mesh attribute is assigned to the node; otherwise, nullptr. |
| light | Light node attribute. ImportLight structure pointer if a light attribute is assigned to the node; otherwise, nullptr. |
| camera | Camera node attribute. ImportCamera structure pointer if a camera attribute is assigned to the node; otherwise, nullptr. |
| transform | Node's transformation matrix. |
| data | Node metadata. |

};ImportTexture Structure#
This data structure contains metadata on an imported texture and has the following set of properties:
| filepath | Path to the texture file. |
| original_filepath | Path to the original texture file. |
struct ImportTexture
{
String filepath;
String original_filepath;
};ImportSurface Structure#
This data structure contains metadata on an imported surface and has the following set of properties:
| filepath | Surface name. |
| filepath | Path to the mesh file. |
| min_visible_distance | Minimum visibility distance for the surface. |
| max_visible_distance | Minimum visibility distance for the surface. |
| material | Material assigned to the surface. ImportMaterial structure pointer if a material is assigned to the surface; otherwise, nullptr. |
| target_surface | Morph target surface number if any; otherwise, -1. |
| data | Surface metadata. |
struct ImportSurface
{
String name;
String filepath;
float min_visible_distance = -Consts::INF;
