This shoud trigger and error with the MS compiler (error C2719), but it actully does not. Anyone care to explain why? Disabled somehow?</P> Mon, 19 Nov 2012 19:13:17 GMT Emil_K_ 2012-11-19T19:13:17Z https://community.intel.com/t5/Intel-Embree-Ray-Tracing-Kernels/How-is-embree-passing-aligned-function-arguments-and-still-does/m-p/953036#M232 <P>I noticed in the file heuristic_binning.h, there's a type&nbsp;PrimInfo, whose c'tor accepts BBox3f by value, this will invoke a copy c'tor, but BBox3f has alignment inherited via Vec3f&lt;float&gt;.

As a workaround one has to pass all values by reference that need alignment. I fixed that bug in the git repository of Embree, check it out here embree.github.com</P> Fri, 18 Jan 2013 09:07:12 GMT https://community.intel.com/t5/Intel-Embree-Ray-Tracing-Kernels/How-is-embree-passing-aligned-function-arguments-and-still-does/m-p/953037#M233 SvenW_Intel 2013-01-18T09:07:12Z
