Hello,
im new to lib3ds but need to export geometries into the 3ds-format. I
wasn't able to find any information that
would help me to understand how 3ds works. Like what nodes,meshes,faces
actually are and how they have to be defined.
I did something like:
Lib3dsFile* file =lib3ds_file_new();
Lib3dsMesh* mesh=lib3ds_mesh_new("the_mesh");
lib3ds_mesh_new_point_list(mesh,(Lib3dsDword)vertices.size());
lib3ds_mesh_new_face_list(mesh,(Lib3dsDword)(vertices.size()-3));
for(int i=0;i<vertices.size();i++)
{
mesh->pointL[i].pos[0] = vertices[i].x;
mesh->pointL[i].pos[1] = vertices[i].y;
mesh->pointL[i].pos[2] = vertices[i].z;
}
for (int j=0;j<vertices.size()-3;j++)
{
mesh->faceL[j].points[0]=vertices[j].x;
mesh->faceL[j].points[1]=vertices[j+1].y;
mesh->faceL[j].points[2]=vertices[j+2].z;
}
lib3ds_file_insert_mesh(file,mesh);
std::string* filename = new string("C:/test.3ds");
lib3ds_file_save(file,filename->c_str());
It writes an 3ds-file but sketchup wasn't able to load it (some error
about incorrect vertexindices).
The API-documentation of lib3ds isn't that helpfull either, so where
would i look to find that information?
Thanks, Johannes
