Terrain vs Nurbs

[only3d]

im creating a new topography (ive made some before)

and i wondered which is better?

i know how 2 make both and with the same ease but is there a reason 2 choose 1 over the other?

let me know

I've never used nurbs for creating terrains, so I can't really speak to that... but I guess the reason I've never gone that route is because I can do everything I need to by using terrain. It's a safe bet.

so may b u can tell me how to refine the terrain mesh?

cuz right now the nurbs look much smoother and more accurate

Here's my basic workflow:

 

- Trace contours from civil plan

- spread coutour splines in z axis to represent thier proper elevations

- add "normalize spline" modifier (lateral distance between vertices should be about the same as the average distance between contours)

- select all splines and use the terrain compound object tool

- add relax modifier (optional)

- add subdivide modifier to create necessary faces where needed for editing.

 

I hope this helps!
