Following Norbert Kern's 'Mountain forest', I wanted to show here an
example of the easy use of the Displacement function in Poseray, and
which is not enough known, I guess.
First make an object and an uv-mapped texture. Then import in Poseray.
A first image shows the used settings in Poseray:
- a displacement map can be made with Gimp, based on the image map used.
it should/could be blurred/dilated with Gimp, then with IC;
- amount of displacement -0.01 (black) and 0.02 (white); only the x and
z components in the case of this wall;
- adaptive subdivision (threshold 0.05 to 0.1 according to cases);
- after this, 'Displace geometry' generates the displacement of the object.
The second image shows the result rendered in POV-Ray.
