This is awesome Konstantin!

Amazing as always

Incredible !! 😎✌

Great, thanks

Great content, love it - how would you take this further and include the cuts, fills and maximum and minimum slope angles for the roads?

Thank you! A very clear and to the point tutorial. Keep it up!

Great tutorial. It does work, althought I can't fully say I know why it works :D

Really cool stuff! is this technique able to work with a curve instead of a circle?

Amaizing, please could we get a tutorial on projecting houses(building volumes) on a slope?

Hi, Konstantin. Thanks for the great job, very useful!! I´m trying to modulate the min and max width with a ramp (based on the curveu attr from the curve), with no results. Any hints? Thanks!!

Hello, great video! Is there a way to extract the curve that shaped the "road"? I blasted the masked points (to only extract the road) to then try to get a curve... it works, but not that well and I wonder if there is somehow, maybe via wrangle to extract the curve that shapes the road (basically 'end1' node but with the correct P.y).

Hi Lia, you could add an attribute wrangle with v@P.y = f@height; either before or after the attribblur1-node.

Thanks for the tutorial, it's very useful ! I wonder is it possible to conform the other way, for example I have a road that is close to the shape of the landscape, and I want the landscape to conform to the closest points of the road?

Hi Toni, yes sure, you can use functions such as xyzdist(), primuv() and smooth() in volume wrangles, as well.

Solid gold man. 2 Questions for you. 1: would it be possible to add a subtle noise in the smooth function to the road width? So to have a path that looks slightly more organic. Question 2: would it be possible to detect when the road is going through a mountain too steep and place a tunnel or deflect the road?

Thank you! Q1: You could globally add noise to the max value before the smooth function: width_max += noise(v@P * 0.1) * 40; or transfer and add some attribute you have prepared on your curves: float deform_crv = primuv(1, 'deform', prim, uvw); Q2: You could increase the heightfield a few meters to make room for a tunnel when exceeding a certain slope. Tunnels themselves are not possible on a 2D heightfield. Also all this more advanced things such as tunnels, bridges, crossings need lots of thought and preparation steps and possibly would not be done right in a single volume wrangle.

@@KonstantinMagnus oh yes of course. I meant faking just the entrance of a tunnel :)

Hi Konstantin! Do you know is it possible to reverse the process - in case I've created an interesting road spline and wanna fit a heightfield to it?

Hi user..., making a height field flow through points or curves is possible with multivariate interpolation: procegen.konstantinmagnus.de/multivariate-interpolation My Houdini friend @adrianpan9211 contributed a suitable python/numpy script writing directly into the heightfield.
