Create a Wireframe Shader with Shader Forge

Question

Hello, I 've made a procedural mesh which moves like this video: https://www.youtube.com/watch?v=V2zzUbfcnQU&list=LLLxo8D3kLk4LTu_WjRWWPjw

It only has the default material now. I want to make it look like this picture: alt text I think giving it a custom wireframe-effect shader and material will work (, right?) So I want to create a wireframe shader with Shader Forge. However I don't really know where to start. :-( I think some keyword might be VertexColor, Alpha, and so on? So I am here to ask for any clues or tutorials.

Also, it seems that there is another way to make this moving wireframe terrain-- Write a wireframe shader whose vertices' position will change (I think it's called vertex shader, right?) and apply it to a plane mesh, instead of creating a mesh and moving its vertices via the Mesh class scripts (which is what I am doing now). Which way do you think is better? And please give me some instruction! Thanks for your help!

Unity Answers is not a good site to ask for clues or tutorials - it's generally intended for specific technical questions and there's s lot of material to cover if you've never looked at shaders before.

If you want to understand what a vertex shader is, how colour gets applied etc. I recommend you look at https://en.m.wikibooks.org/wiki/Cg_Programming/Unity

If you simply want to get a wireframe effect in your built game, I recommend you look on the asset store - there's at least two options there I'm aware of and they'll be much quicker to implement than rolling your own.
