Terrain road notch and mound

[komyali]

I have isohipse in auto cad, and middle line of street in autocad, send that to max and every isohipse move up 1 m, then converted to terrain, now I have middle line of street also moved up so it is on top of isolines. My question is how to create notch and mound with width of street? one solution is http://rendering.ru/ru_en/splineland.html but at this time it is too expencive for me... so I am thinking about loft or sweep profile of street and midle street line to be my guide of loft/sweep profile(with notch and mound) and later use pull and push for mound to get normall shape? Does anybody have faster vay?

P.S. http://www.4d-technologies.com/geotools/index.htm

did anybody tried this?

If I understand correctly then try:

 

Take your center line and extrude it up high enough to poke through your road/terrain everywhere and then add a shell to the appropriate width. If you then right click with that object selected and go into the object properties and un-tick renderable.

 

With Vray you can now use the distance texture to apply 2 separate textures based on the distance and overlap between objects. You just use the line object to tell the terrain object where you want the second texture to be applied.

 

In the final render you will only have the terrain object rendering, but it will have 2 textures.

These aren't the exact technique I'm describing but they all use the distance texture in a creative way.

very very interesting!

@Corey I like it, but my terrain is big and I dont like displace, so my all rendering are without displace map, but I will try it. P.S Distance map would not give realistic look of notch and mound because it wold be same distance from object(road) and notch depend on slope variation so if slope vary your notch need to varay too( it will be bigger or smaller) and that is not happening here? also I forgot to say my notch an mound need to be 45 degree on every section of road.

@Jose, I like it, I will try it, but my problem is not road but notch and mound, and on slope terrain with morph road become tilt on one side and in road engenering you dont want that, road cant be tilt. That is the reason why notch and mound exist but thanx anyway I can use this tutorial for other stuff

nop, I can do that without ant-stitcher till now best one is splineland but I want to do withouth plugin, I think I will make it with sweep
