Converting ZPic to RGB-Pics in FX-tree 2005-03-02 - By peterb
Back
which was very interesting btw.
this leads me to think that the pixel parser could do with some usage
examples,
as this is not a very obvious node to use.
here is the answer from Luc Eric again:
.....
the difficulty lies in the fact that zpics are not image, it's the zbuffer
and the values
go from 0 to as much as minus 100,000, which you want to compress in a
smaller range.
The first step is shaving the range that you don't need with the pixel
parser.
First load the .Zpic in the compositor. Then add a Pixel Parser node.
type in the formula : 1-((1-pixel)*100000)/a1
Now, using the "a1" slider you can narrow down the ZPic around 0 to 30 (the
distance in Softimage Units). Type in a greater value if appropriate.
You can fine-tune the contrast by adding a Luma Adjust node.
A file output node to save the final .pic file
