I sort of expected you would want a repro case for that, but it really is as simple as it sounds. …
I hope to have something to show by the end of August. If you have any questions or comments, feel…
Here I plotted 9 correct weight values for Gibbs vector to interpolate from 0° to 180° exactly l…
mmozeiko, thank you! I mentioned you in .
The real deal breaker for me is interpolation: while Gibbs vectors interpolate just like quaterni…
Oh, only IDE created projects have set warning level by default. If you are compiling in command-l…
you can enable most compiler warnings with /W4 or /Wall The default compile settings are pretty le…

I should double check my warnings then because I did not receive a warning on compile. When I get …
BytesToWrite is DWORD (which WriteFile expects). DWORD is 32-bit number. 32-bit number can store m…

Very nice! (on insobot quotes, not IRC split/join nonsense)
Over the last month or so, I've been working on two projects related to insobot, though the bot it…
Yes you can, I don't mind. WTFPL license :)
mmozeiko, what's the license of your perf test code? Can I add it to under public domain?
Yeah, seeing same results on MSVC2017, with "/fp:fast /Ox /Ot": with "/Dinline=__forceinline /fp:…
Hey! So I've been using 4Coder for a while, and I recently found a bug (happened to me twice now).…

For Skylake the performance of MULPS and DIVPS is the same as for MULSS and DIVSS.
I think it'll be fair to compare 1 div to 2 muls (given 3 divs of Gibbs vector vs 7 muls of quater…
I'm glad you are at least having fun with it! These are all pretty interesting issues you've broug…
Hi Sorry about the crash! It does sound like it might be an out of memory situation. The data st…

At some point it needs to be rotated 180° compared to the starting position. At that point your …
