comment Purple screen when using vertex shaders
This was a big topic years ago on the XNA forums. See these search results: xboxforums.create.msdn.com/search/… Also, it was fixed often by this answer: xboxforums.create.msdn.com/forums/p/95682/571781.aspx#571781

comment How to avoid Gimbal Lock on Rubik's Cube
@AndrewWilson A real life rubix cube is only able to rotate around 1 axis at a time until the full 90 degrees of rotation is accomplished. Based on your gif, you appear to be rotating a group of 9 small cubes around 2 axis at the same time. Typically, one group of 9 small cubes would rotate around one axis then after that a different group of 9 small cubes would rotate about a different axis. Only 3 small cubes could be involved in both rotations, you show all 9 cubes involved in your simultaneous 2 axis rotation.

comment How to avoid Gimbal Lock on Rubik's Cube
@AndrewWilson What makes you think your original problem is gimbal lock? Gimbal lock is often a label people put on all sorts of 3d rotation issues that aren't really gimbal lock. A matrix concatenated with an 'axis/angle' matrix will give the same result as a quaternion concatenated with quaternion made from the same axis and angle. Why do you think you have gimbal lock?

comment XNA 4.0 - Bounding Boxes
There is a fundamental problem with your algorithm. The box's min/max vertices are not simply the min/max vertPositions like you are working towards. To create the actual Box.min, the X component may be from one vertPosition while the Y component may be from a different vertPosition and the Z component from yet another.

Glad you got it. Your Xml file can be used for lots of game initial game settings and configurations.

comment C# XNA - Can't Deserialize Element
Your error pops up when your code runs your xmlManager class. The point is, you don't need that class. Delete it. That class can only act upon XML. You don't want to ship XML with your game so there is no point in writing code to parse XML. Let the content manager do it automatically to the xnb.
