Displacment mapping

Post by John Pon » Sat, 15 Sep 1990 00:03:57

     I am looking for some information on displacemnt map      ent mapping.
     Displacemt ent mapping is simm ilar to tesxt   xture mapping or m bump mapping
         except that a   in displacemt ent mapping the nrom   ormal is actul ally "displaced"
     to cause a deformation in a model (this is how              l, .  This h is how grouove    oves in a*are
      o  models ed  .  Displacement mapping appears to be fairly new and I have not
     been able to find any   y papers on it.  I would appreciate any information
     or references that I could use to find out more about it (particularly
     how to implement it).

1. problem with displacment maps

I'm having an odd problem with displacment maps in V3.0.5 I've tried this
on the Mac version and PC version with the same results:

1.I create type in an Alpha Channel of An RBG image
2. I copy this channel to clipboard and create a new image and copy the
alphs image into it (and save)
3. I then swtich back to original RGB turning off alpha chanel and run
displacement using the new image with the alpha channel image as a map.

The image is displaced OK BUT..there is a bunch of somewhat legible type
that says something like "photoshop 3.0 files.." and a bunch of other stuff
I can't read. I have repeated this with different images on different
platforms with the same results! I don't recall having this problem with

Anyone know anything about this?
