Title: Inside a U Tube Post by: haltenny on January 13, 2017, 05:21:33 PM Inside a U Tube (http://nocache-nocookies.digitalgott.com/gallery/19/3810_13_01_17_5_21_33.jpeg) http://www.fractalforums.com/index.php?action=gallery;sa=view;id=19943 This is just something I discovered by accident. I was tweaking a formula set that had RandCubesIFS in it. I was adjusting the scale setting and ventured into the negative scale, and suddenly I was inside the RandCubesIFS shapes, instead of looking at them from the outside. At first I was inside a sphere, then a cone, and this one is inside one of the U shaped tubes. It's probably not difficult to achieve, but I did fail when I tried to duplicate it from scratch. SphereHeightMap (with no map)~ RandCubesIFS and AmazingSurf on this one. Also one of the rare times I used reflections. Almost looks like mother of pearl effect... |
