Title: Heightfields
Post by: JosLeys on November 09, 2010, 01:15:18 PM
My algorithm in UF is coming along rather well, although I'm still working on it.
There are 57 images like the one below at http://www.josleys.com/show_gallery.php?galid=337 (http://www.josleys.com/show_gallery.php?galid=337).

These are so beautiful! even if the shadows are not perfect yet.

I asked him, but he said he still wants to debug it ;)

Yes, well, I'm still working on it.
Trying to add in some fake ambient occlusion like in this image :

Hi Jos,
Seems like the formula is workiong well. When are you going to publish it?

You just need to paste the http link, the forum does the rest.

To bib,

- Thanks, I modified the post, now showing just the http: link
- I'm still trying to improve the coloring scheme, as it is not user friendly in its present state, and I don't want to set up a helpdesk once it is published. No idea yet on timing...

After an email form Jos I have started a totally new approach to
heightfields which doesn't use meshes. It is still very experimental and
very buggy but here is an example with a 3500x zoom into the mandelbrot set.
It takes about 5 minutes without antialiasing, and about 1.5 hours with
(which was used for the attached image.)
