Re: [osg-users] VPB texture disappear
Hi Paul, If NPOT is the issue, then apparently VPB requires NPOT support at DB build time, not just at run time. I found that creating the same DB on my Windows laptop with Quadro 1500M works great. Well, that would make sense since OpenGL operations are used (within an OpenGL context) when resizing and compressing the textures. But what video card do you have that doesn't support NPOT? I would think that's a rarity nowadays...

Re: [osg-users] VPB texture disappear
Interesting... Neither osgdem nor vpbmaster show a --pot command line option in their help output, but neither of them complain if --pot is present on their command lines. The cache file output from osgdem doesn't appear to be different with or without --pot, which makes me think this must be a vpbmaster option. Just to be safe, I put --pot on both the osgdem and vpbmaster command lines, and I still get the same results. So this isn't the cause of the issue. Any other suggestions? Robert, I'm not specifying the --compressed option when I build the DB, so I don't think I need support for compressed NPOT textures. (I'm assuming compression is off by default, as there doesn't appear to be a --no-compression option.) JS -- This is a MacPro with GeForce 8800. It supports GL_ARB_non_power_of_two. Nonetheless, there is something about the MacPro/GF8800 that is causing the issue at build time: When I view the DB built on the Mac on either my Windows or Mac system, the issue is present. When I build the same DB using the same source data on Windows, the issue is not present. (Ideally I'd like to use my Mac; building VPB DBs is one of the main reasons I bought this system. It builds the DB some 20x faster than my old clunker Windows system.)

The cache file output from osgdem doesn't appear to be different with or without --pot, which makes me think this must be a vpbmaster option. The non power of two support is pretty new. I've just checked the build options and it's set to round to a power of two by default - which is how it originally worked. This is for controlling whether the output imagery is clamped to a power of two, Using -npot enables the use of non power of two output imagery. Just to be safe, I put --pot on both the osgdem and vpbmaster command lines, and I still get the same results. So this isn't the cause of the issue. Any other suggestions?

I vaguely remember issues about read back of texture objects being faulty under OSX so perhaps this is the the problem. (Ideally I'd like to use my Mac; building VPB DBs is one of the main reasons I bought this system. It builds the DB some 20x faster than my old clunker Windows system.) Not using Windows for thread and file system intensive work is sensible for sure. But... NVidia drivers under OSX are a bit flaky, it seems that NVidia OSX drivers have about the same quality as ATI drivers under Windows + Linux. Try dual booting the machine to linux, at least then you'll know you can select a decent filesystem and graphics drivers.
