sizeof( swizzle::glsl::naive::vector< float, 3 > ) == 16 on MSVC #2

Closed Sairony closed 9 years ago

MSVC doesn't do EBO beyond the first base, so inheritance needs to be chained which is a bit of nuisance. While it does mean vectors take more space than needed, it also sadly prohibits using it as a base type if one wants to send the data to GPU in vertex buffers since size wont match.

Which MSVC are you using? In the sample there are static_assertions in place (like https://github.com/gwiazdorrr/CxxSwizzle/blob/master/sample/main.cpp#L14), which should detect this with a compile error. They are OK on MSVC 2010 & 2013. Which version are you using?

Can't repro.
