Visualization for Windows Media Player

Visualization of Windows media player is really really amazing, and I often spent hours just looking at the video and listen to the music. Especially, I like "strawberryaid" and "illuminator" very much. It chould be even more cool if you choose "Randomization".

You can download more visualization from Microsoft’s website, http://www.microsoft.com/windows/windowsmedia/player/visualizations.aspx. With Windows Media Player 11 SDK that MS provides, you can even create your own visulaiztions, wonderful. http://msdn2.microsoft.com/en-gb/library/aa386694.aspx

Pinhole Camera Model

opencvref_cv.htm

The functions in this section use so-called pinhole camera model. That is, a scene view is formed by projecting 3D points into the image plane using perspective transformation.

s*m' = A*[R|t]*M', or

 [u]   [fx 0 cx] [r11 r12 r13 t1] [X]
s[v] = [0 fy cy]*[r21 r22 r23 t2]*[Y]
 [1]   [0  0  1] [r31 r32 r33 t2] [Z]
                                 [1]
