The label.box.heading is not correct as visulizing in Open3D GUI. about waymo-open-dataset HOT 2 CLOSED

I do not know what Open3D GUI expects. The heading we provide is the angle required to rotate +x (vehicle frame) to the surface normal of the front face of the labeled box.

Also make sure you interpret length/width properly. https://github.com/waymo-research/waymo-open-dataset/blob/master/waymo_open_dataset/label.proto#L28-L35

I mistook the order of length and width.

    // Box coordinates in vehicle frame.
    optional double center_x = 1;
    optional double center_y = 2;
    optional double center_z = 3;

    // Dimensions of the box. length: dim x. width: dim y. height: dim z.
    optional double length = 5;   
    optional double width = 4;
    optional double height = 6;

Thanks a lot!
