strange results when running VSG vsgViewer.cpp in Windows 10

[RKiserAL]

Hello All

I just downloaded the latest version of VSG (Version 1.0.5) and saw some strange results when trying out the example: vsgViewer.cpp

When I ran it pointing to lz.vsgt, all was fine and I saw a display of topography.

When I ran it pointing to teapot.vsgt, I got the following error messages:

ERROR: Unable to match userObjects got NumUserObjects instead.
ERROR: Unable to match children got 1 instead.
ERROR: Unable to match matrix got Key instead.
ERROR: Unable to match subgraphRequiresLocalFrustum got "batch" instead.
ERROR: Unable to match } got Object instead.

Just a blue background was displayed.

Both of these .vsgt files were obtained from the data sub-directory of the vsgExamples directory.

Is this some kind of pilot error, i.e., I am specifying a file incompatible with vsgViewer, or something else?

I am a complete newbie with VSG, so I'm suspecting pilot error. I do, however, have quite a bit of experience with OSG.

For what it's worth (if anything):
Windows 10 x64
Visual Studio 2022 Community 17.5.3
Vulkan 1.3.243
NVIDIA GeForce GTX 1080

Any ideas?

Thanks in advance for any help,

Bob Kiser

Hi Bob,

From the look of the error it sounds like the vsgExamples/data that you are using is an early incarnation, prior to the VSG-1.0 release and contains no longer valid .vsgt files.

You could try updating to vsgExamples master or vsgExamples-1.0.x.

Cheers,
Robert.

Yes, that did it. Thank you for your quick response.

How I got an old version I don't know as I thought I got them from the latest GitHub repository. So, my screw-up.

Looking at the history of teapot.vsgt shows the update from last June: vsg-dev/vsgExamples@27fa5eb So my best guess is that you must have had a clone the vsgExamples repo before last summer and still had this hanging around on your VSG_FILE_PATH.
