Question by Marteen21 · Apr 19, 2015 at 03:31 PM · shaderoutlineedge detection

Outline every edge not only its "silhouette"

I have a 3D terrain with orthographic camera view and i am trying to get outline to every edge where the terrain changes. I tried modifing the built in toon outline shader and even the edge detection script, but i have no experience in these rendering methods.


alt text

The black line shows the outline, and the red shows where i want to get the outline as well.

"Where the terrain changes" it not too descriptive. Does the texture change, or just the angle of the normals? A shader could be written for the latter case, not sure on the former, but in any case for a beginner it'd be far easier to just incoporate the lines into the texture itself at the required places.
