Path Finder using a Recursive Process – Example 8.5

A not uncommon task for Landscape designers is to draw paths through the landscape. If you are working on a “flat site” (something which doesn’t exist) or if you are just deciding to… Continue reading

Adding Topography to the Site Model – Example 20.2

So you have a nice 2D document started and now you want to add some topography? Well, it is possible with Elk, and the process seems pretty straightforward at first, but unfortunately it… Continue reading

Fractal Terrain Generator – Example 9.3

While not typically something used by landscape architects, many Computer Generated Landscape artists use procedural world generation software to create landscapes that have no basis in actual, real world landscapes, but can look… Continue reading

Recursive Subdivision of a Topographical Surface – Example 8.3

This example is partly regional analysis, partly trying to make cool images, and partly could have some practical applications. I’ve seen a few scripts floating around called “Recursive Subdivision of a Surface.” One… Continue reading

Changing Topography with a Curve Attractor – Example 4.5

Many of the examples we looked at in the 2D Patterns can be adapted to create geometry in 3 Dimensions. In this exercise, we use the same logic employed in the Curve Attractor Example to… Continue reading

Creating Surfaces with Lofts – Example 4.4

Another common way to create surfaces is to use a tool known as the “Loft” These can be done in either Rhino or with Grasshopper, with the advantage that the Grasshopper surface is… Continue reading

Creating an Editable Surface with Points – Example 4.3

In the Example 4.1 we looked at creating a surface with a Grid of Points in Grasshopper, and in Example 4.2 we looked at creating a Patch surface in Rhino. The problem with using the… Continue reading

Creating a Surface from Contour Lines using Patch Surface – Example 4.2

Often you will start a project with existing topographical information in the form of contour lines in a CAD program. This will allow you to quickly and easily develop a 3D model in… Continue reading

Random Topography and Surface Analysis – Example 4.1

Moving on from 2-Dimensional patterns, these next examples show some tips on how to create and analyze surfaces in Grasshopper and in Rhino. Some can be made with control points (think spot elevations… Continue reading
