I am sorry, I am really unexpericed with Blender although I tried to put some time into it. So essentially I want to create something like this:
From a Digtial elevation Model (DEM) that is a simple image going from black to white. Like this:
I tried a lot of options and I am a little lost. I am coming from the gis world, so this is really different to me. I followed this excellant tutorial to create a shaded relief.
But I would really like to show the edges and vertices. So my current steps are more or less:
- add a plane
- Subdivide it by ~100 cuts (instead of using the adaptive subdivision as in the tutorial)
- Select the Cycles Render engine
- Add a new material
- Set Displacement to: "Displacement Only"
- (Maybe add a vector displacement)
- Turn on Freestyle under render properties
- Select color etc. for edges...
But now I really do not know if this is the right approach and how to proceed. I'd be thankful for any tip or pointer to a ressource. I saw this video here:
I think the key is the rendering of the wireframes. However, I yet did not find a way to do this for a simple black and white image like the above one. In case anyone has a good starting point I'd be super grateful!:)
The thing is the subdivision surface (sorry this is certainly not the correct wording) is not 3d. Its just flat...
I can select all edges and say "Mark Freestyle Edge", but it will just be an "Overlay":/
