Re: [sumo-user] 3D Visualization of SUMO

[Keith Loiselle <keith.loiselle@xxxxxxxxx>]

Michael,

Thank you for your help.  I have tried OSG with v1.5.0 on both Windows 7 (version 6.1.7601) and Windows 10 (version 10.0.18363.720).  The Windows 7 computer only has Intel integrated graphics, but the Windows 10 computer has an Nvidia Quadro M1200.  I updated video drivers for both computers.

I from the OSG-3.6.3/bin folder ran the command "osgview car-normal.citrus.obj" after copying the obj and mtl files into that folder and it did display the 3D model of a car.

I tried copying the DLL files from SUMOLibraries\OSG-3.6.3\bin\osgPlugins-3.6.3 to the sumo/bin folder and the 3D models do display, but also the vehicle color shows up as a spheroid:

I could configure the color of the vehicles with the View Settings window, but I could not make the spheroid go away.  Is there a way to disable the  color spheroid?

Also, if changing the camera angle with the vehicle tracking requires modifying the source then I'll look into building the code.

Thanks,

Keith

Hi,
please post your exact Windows version and check whether there are newer
OpenGL drivers available for your graphics card. It would help as well
if you could clone https://github.com/DLR-TS/SUMOLibraries (Attention
this puts 2GB on your disk) and try to run the osg examples in OSG-3.6.3/bin

Best regards,
Michael
