Functions

gltforge_load_mesh^⚠

Parse a glTF file and build a UnityMesh for the given node.

gltforge_mesh_index_format^⚠

Returns 16 if all submesh index buffers are u16, 32 if they are u32. The format is the same for every submesh and is determined by total vertex count.

gltforge_mesh_name^⚠

Return a pointer to the mesh name as UTF-8 bytes (not null-terminated). out_len receives the byte length. Use Marshal.PtrToStringUTF8(ptr, len) in C#. The pointer is valid as long as the handle is alive.

gltforge_mesh_positions^⚠

Return a pointer to the position data (tightly packed [x, y, z] floats, left-handed). out_len receives the total number of float values (vertex_count × 3). The pointer is valid as long as the handle is alive.

gltforge_mesh_release^⚠

Decrement the reference count of a UnityMesh handle. Frees the underlying data when the count reaches zero.

gltforge_mesh_retain^⚠

Increment the reference count of a UnityMesh handle.

gltforge_mesh_submesh_count^⚠

Return the number of submeshes (one per glTF primitive).

gltforge_mesh_submesh_indices_u16^⚠

Return a pointer to the index data for submesh_idx as u16. out_len receives the number of index values. Returns null if the format is u32 or the submesh index is out of range.

gltforge_mesh_submesh_indices_u32^⚠

Return a pointer to the index data for submesh_idx as u32. out_len receives the number of index values. Returns null if the format is u16 or the submesh index is out of range.

gltforge_mesh_vertex_count^⚠

Return the total number of vertices across all submeshes.
