anyone knows about a complete explanation
of the SSC and DDM?

OK..
i gonna respond to myself: ;)
finally i´m understanding everything in the SSC
but i´m still looking for a better
explanation of the DDM
knowing that it works with polar coordinates
and that d is the distance and r should be
the angle to the vertical line
is like knowing 0=false and 1=true for
understanding boolean algebra

hope someone can clarify the funktion
of the DDM beside the try putting some formulas

DDM is there to modify distance dynamicaly. I don't know how else to put it. :p You have all the variables, everything else is your own creation.

DDM and DM work by specifying a source coordinate to go with every target coordinate. Most people imagine it to be the other way around.

This means that, for each point on the screen at coordinates (x,y) or (d,r), the color from another pixel (x',y') or (d',r') is used. If you use a formula that only shifts the coordinates slightly, a movement results. Because calculating a new pair of coordinates for each and every pixel is not possible real-time, tricks are used.
The DDM only allows you to modify the distance, while the DM only operates on a grid of points (hence grid-size) and uses linear interpolation for the points in between.
