Hi Kim, Ümit,
When you run the example application the fftss.dll will need to be in the same directory as the exe or by adding the directory it’s in to your PATH environment variable (if you’re in windows)
Actually FFTSS doesn't have a DLL, it's a static-link library. FFTW has a DLL (though you could compile it to link statically too if you wanted).
When I run the example I get errors as follows.
[... snip lots of shader errors ...]
I think these all related about driver because of my driver 2.5 years old and it's last updated driver support only opengl 2.1 and GLSL 1.20. I think I can't run osgOcean in my company computer. I have to use another newer one. Any suggestions?
Well, some drivers are more permissive than others regarding implicit casts from vec4 to vec3. Some of the errors above seem to be what some drivers would only give warnings about.
I'll try to tighten up the shaders so they give no warnings, that will reduce the number of errors you get, but it won't eliminate all of them, because others are about texture rectangles, which your card/driver doesn't seem to support. The full-screen effects require texture rectangles (NPOT textures) to be able to render at the same resolution as your screen (which is in general not in power-of-two resolutions)...
Tuth is, 2.5 years is a long time in Graphics. I assume you have a good reason for not updating your driver, but there's little we can do to support such old drivers and still retain all functionality. We could do it if funded to do so, but if not we have to choose a subset of cards/drivers we need to support and do what is necessary for those.
If you want to try and fix all errors, of course, we'll be glad to fold your changes into the source :-)
