I guess my last question is (not to you directly, just Boost developers in general) - I wonder if either of our swizzle implementations would be considered useful to ublas or MTL ( http://osl.iu.edu/research/mtl/ )?
I use swizzling all the time (and more than just xyz) but it's in actual shaders using Cg, not C++ code. I'm not sure if that's because I have never had them exposed to me in C++, or if I have just not needed them.
I think swizzling tends to be used mostly in graphics programming, and neither ublas nor MTL describe that as their problem domain. Perhaps it's too specific to be included with those libraries. I notice that that Vault - Graphics folder is empty...maybe some OpenGL work needs to be done.
I use swizzling all the time in shaders as well, but not in C++. I used to - back when I started writing the library - but that was before capable programmable GPUs were mainstream and we actually used C++ for vertex transformations and such. As far as I know, "we" are the only ones who use swizzling, but that may well just be my ignorance talking... -- Daniel Wesslén
