visual studio BKM and ensuring HLSL files are built after changes are made

 so...you have an .hlsl file and you want to make sure your changes trigger a rebuild do not use the pre-build for the solution. instead, click on the .hlsl and use a custom build tool. the final thing you have to do is to tell visual studio to treat the output as content and fill in the content field with your compilation output artifact(s).

Stochastic LOD sample from nvidia

neat sample, needs minor cleanup to compile on my VS2019 solution. may not be anything wrong with the write environment, etc. just my config:

several #include <iostreams>

disabled 'treat errors as warnings'.

several live objects after sample executes/shuts down, not going to resolve at this time.

row major and column major major confusion

Capturing for posterity:

TL;DR: C is row major, XMMATRIX* is row major, HLSL is column major. 

A comment here explains rationale:

And you can tell HLSL to flip to row major.
