Stream or Brook

[Peter Eichel]

Any advise on adding a realistic stream or brook to a DTM.

[Benson Shaw]

Depends on how realistic you need it. Here are some ideas:

For a pond, draw a 2d poly slightly larger than the contour defining the water level, convert to 3d poly with any fill color, add Nature Water texture from the VW library.

For a stream, tilt the poly to slope of stream. Perhaps use several polys if there are cascades or drops. Vary the texture scale, rotation and bump for the various polys.

Or make a NURBS poly with the various cascade drops (again, a bit wider than the contour for water level), and Create or Loft Surface. Apply water texture.

Or photograph a section of a real brook and import that as an image texture- rocks and all. Apply it to NURBS or flat poly surface.

Benson:

I used a copy of the original polyline that formed the brooks winding path in the DTM, converted it to a NURBS curve and "extruded along path" an appropriate shape. Worked beautifully.

Thanks for the tips.
