Moving Terrain with shader?

Unity Engine
1

hey everyone.

i am pretty new to shaders so i hope this does not sound too weird :wink:

i created this effect with mesh manipulation: http://www.randoom.net/movingterrain.mov

basically it is a grid plane and i manipulate the height of vertices. since this is a bit too heavy on performance, i thought that this could be something that a shader could do pretty well.
when i looked into shader tutorials, i found stuff about lightning and all those rendering things but never really about manipulation of basic vertex transform parameters.

can anyone point me in the right direction for that task? or tell me that my idea is really bad? :stuck_out_tongue:

thanks for your help!

Have a look ath the Unity surface shader examples.

Search for “Normal Extrusion with Vertex Modifier”.
This is an example showing you how to manipulate vertecies with vertex shaders.
