3D visualization of overlapped vectors doesn't work fine.

I'd like to know how to make the 3D visualization better when the layers are overlapped, as in the image below. The vectors are stained and sometimes pixelated. In 3D visualization of world imagery, everything works fine. The vector view is the opposite.

    Hi carmiin,

    Hard for me to tell what's going on. A couple of questions:

    What version of Global Mapper are you using -- it looks a little old. Is it version 18? (We're up to version 20 now).

    Are you running on a laptop or other integrated GPU system? What version of OpenGL are you using?

    Are those vector contours (for example, from SHP format) draped over terrain data? In your 3D View Properties, do you have the "Draw 3D Vector Features Reflected on Terrain Surface" checked? It does kind of look like the vectors have been "rasterized" onto terrain, since you can't see the contours in the rear appearing before those in the front.

    Best regards,

    ~Jeff
