If someone needs the dx11 base and terrains C++ sources, here are the conversions from d3dx to DirectXMath I did some time ago, the project and the solution files are in VS2013 format: http://1drv.ms/1BP63MU
Please note that code is provided "as is", and I didn't add particular stuffs except the math library conversions and some aligned allocations due __m128 use in XMMatrix and XMVector (sometimes even useless aligned allocations, but they still work ).
If you have issues opening the archive, please use the last preview of 7zip http://www.7-zip.org/
If you don't have Visual Studio 2013 you can install the express desktop version for free, or you can recreate manually the solution and the project files.
EDIT: I forgot to mention that those projects use DirectXTK as static library in the Texture class (I used DDSTextureLoader). https://directxtk.codeplex.com/
You need to link the library to the project, the default path I used is ..\..\..\DirectXTK\Bin\Desktop_2013\$(Platform)\$(Configuration)
