One of my performance focus areas for this year is vectorization. I am excited to start creating more content and spreading the message about this technology, as it has been a little bit underappreciated in the past. So to kick things off, I am going to launch a blog series and a 1-hour overview webinar.
First, information about the webinar.

Datatype color conversions are a common requirement in 3-D application pipelines. In a simple lighting scheme, these conversions happen at least once per color channel, red, green, blue (R, G, B) per vertex, and in a more realistic lighting scheme, such values are often calculated multiple times for different light components. Color conversion from single-precision floating point values to integer values is typically done by using simple casts, for example intvalR = (int)fpvalR; where intval is an integer and fpval a singleprecision floating point number.
