NanoVDB Viewer options

[Seamus McCool]

I would like to use the nanovdb/view tool to view various .nvdb files and see relative performance between cuda, glsl, and cpu raytraces.  Unfortunately it appears the nanovdb cmd tool has been removed from recent versions of nanovdb, and nanovdb has continued to progress, thus the last version available in the repo does not compile against the latest nanovdb.  

Has anyone updated it or can point me to an updated version?

I also filed an issue with the version that does compile, on the openvdb github site that the OpenCL and GLSL renderer versions do appear to render correctly.  What appears is a very long bar like object.  Has anyone else seen this issue?

Lastly, does anyone have any suggestion for other NanoVDB viewers that will allow me to acomplish my goal, which is swapping .cu/.cl/.glsl shaders in/out for general performance comparisons?
