Today, we’ll take a look at using matrices for linear transformations, which are one of the most common uses of matrices in games. But, before we dive into linearen-USTelligent Evolution Platform Developer Build (Build: 5.6.50428.7875)http://blogs.msdn.com/b/rezanour/archive/2011/10/02/math-primer-series-matrices-ii-linear-transformations.aspx#10378233Fri, 14 Dec 2012 21:00:52 GMT91d46819-8472-40ad-a661-2c78acb4018c:10378233Reza Nourai - MSFT<p>Thanks for pointing that out, I&#39;ll check the numbers when I get a chance and update the post.</p> <p>Glad you&#39;re enjoying the series!

The length of the resulting vector doesn&#39;t match the length of the starting vector. 3^2 + 4^2 + 5^2 != 5.7795^2 + -0.707^2 + 2.3285^2.</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10378030" width="1" height="1">http://blogs.msdn.com/b/rezanour/archive/2011/10/02/math-primer-series-matrices-ii-linear-transformations.aspx#10236056Fri, 11 Nov 2011 05:28:57 GMT91d46819-8472-40ad-a661-2c78acb4018c:10236056Reza Nourai - MSFT<p>Things have been pretty busy here, but I definitely plan on posting more! I&#39;m glad you&#39;re enjoying the series so far. I hope to have the math primer finished soon, and continue with the physics articles. I may also start adding some graphics and GPU articles in the near future.</p> <p>Let me know if there are particular topics you are interested in, and I&#39;ll try to cover them if I can.</p> <div style="clear:both;"></div><img src="http://blogs.msdn.com/aggbug.aspx?PostID=10236056" width="1" height="1">http://blogs.msdn.com/b/rezanour/archive/2011/10/02/math-primer-series-matrices-ii-linear-transformations.aspx#10236047Fri, 11 Nov 2011 04:08:11 GMT91d46819-8472-40ad-a661-2c78acb4018c:10236047Dee<p>Hey Reza, hope you still plan to post here.
