Re: [Openexr-devel] Vector-of-float to vector-of-half conversion?

[James Bowman]

Yes, I have some SSE code that converts four floats in parallel.

I can dig it out if anyone is interested...

Have any of you tried to convert vectors of 32-bit floating-point
numbers to vectors of 16-bit floating-point numbers in a way that
is faster than calling OpenEXR's half-from-float constructor for
each vector element?  Maybe using MMX, SSE or AVX instructions?
