alright! did the @inbounds and @simd and benchmarked again (for different light source position, thats why numbers dont match exactly with the ones above)
cython original code: 27.5 s julia original code: 28.3 s julia with @inbounds: 21.3 s julia with @inbounds & @simd: 19.0 s Looks like a nice speed up to me! :) I ll look into the column-major issue later.
