Unity Raymarching Examples

Example 1:
I tried to Implement this shader based on AlanZucconi Article about Raymarching
https://www.alanzucconi.com/2016/07/01/raymarching/

# ToDo:

1.Help me to Texture mapping Tours in Example 2 something like this https://www.shadertoy.com/view/Xd3XDS

2.Implementing Clouds something like this https://www.shadertoy.com/view/XslGRr

3.making CgInclude for Raymarching and SDF shapes function

4.transform,rotate,scale Abstract object in unity space
