Experience: In addition to querying materials on the Internet, you can also try the functions of each attribute, read more official documents (I always think it is better to read the original documents than to translate them)The second one is intentionally:

No, it's too troublesome. Use text to record it for future query.
The coordinate system M1 is rotated by E, while m2 is rotated by M1, and so on M3.
Then, the coordinate m in E is rotated by the coordinate system. The final coordinate is m1m2m3... M4 * m, and m is the vector.
M1, M2, M3, and M4 are rotating matrices.
Ex = om
M1x = om1
M1 is the coordinate of E after rotation
M1m2 just converted the vector represented by m2 to the coordinates in M2.
M1m2 is the rotation of the coordinat

Some time ago, the touch screen and the Optical Mouse responsible for the project were all input devices. After reading the materials and combining the project code, I made a summary, which basically came from my personal understanding and the Internet.
After linux2.6, Linux abstracts the input device and abstracts the input subsystem, which is the middle layer driven by all I/O devices, provides a unified interface for the upper layer, which separates event reporting and processing, and uses a
hotspot in a public place.
Flip/3D flip
The all-new window management function in Windows Vista allows you to use [Alt] [Tab] to flip between opened Windows. If you use 3D flip, you can use the Windows key plus the TAB key to flip on the stack of a 3D running window, using the scroll wheel or trackball on the mouse, it can also achieve the flip effect.
