I re-added the functionality of getting a road network mesh in commit https://github.com/grepthat/libOpenDRIVE/commit/74a5d0760ff933830750d931325eaeb7a6b9e371 This was accidentally removed when deprecating the viewer. You can now get an .obj like this via code:

odr::OpenDriveMap odr_map("test.xodr");
odr::RoadNetworkMesh road_network_mesh = odr_map.get_road_network_mesh(0.1 /*eps*/);
std::ofstream out_file("out.obj");
out_file << road_network_mesh.get_mesh().get_obj() << std::endl;
out_file.close();

Thank you for your help @grepthat But, I couldn't get some more information such as middle line, junction, etc.. in obj picture(3D Viewer).

Could i get more information from the code?

[pageldev]

Do you mean the junction areas are missing in the generated .obj file?

Best provide an example .xodr

Thank you for your reply @grepthat

I mean that I can get road outline in the generated .obj file, but I can't get the others such as center line.

"Best provide an example .xodr", In this sentence, you mean my opendrive file is something wrong??
