Using Curve Attractors and Graph Mapper to Modify Terrain
In this example, we will follow up on the logic of modifying terrain with point attractors and now modify the terrain along one or more linear pieces of curve geometry. We will be using much of the same logic, so if you are struggling with certain aspects it may be useful to attempt the previous…

Using Point Attractors and Graph Mappers to Modify Terrain
In the previous attractor examples, the focus was on creating 2D patterns with a linear distance falloff. Attractors can also be used to adjust geometry in 3D space, and the distance domain can be modified based on various functions to create more interesting and dynamic geometry. In this example, we will be using attractor logic…

Købmagergade, Copenhagen – Karres en Brands – Case Study 3
This example is inspired by a project by the Dutch Landscape Architecture Firm Karres en Brands in Copenhagen, Denmark, the pedestrian street Købmagergade. I saw the project in its initial stages during a visit in 2009 but haven’t yet seen the final results. The concept is fairly simple. The designer wanted to create an effect…

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 move a grid of points vertically to create a river valley. The logic here is pretty simple. The curve is sketched out…

Curve Attractors – Example 2.3
In the last two examples, we looked at both single- and multi-point attractors, but you can also use attractors with curves (think paths). In this example we will use the concept of an attractor to scale geometry based on the distance of the geometry to the centerline of a path. Written tutorial instructions continue after video: Step One –…

Multiple Point Attractor with Random Point Cloud – Example 2.2
A multi-point attractor follows a similar logic as the single point attractor, although distance is measured in a slightly different way. In principle, however, a multi-point attractor is much more useful than a single point one, and this script can for all intents and purposes replace a single point attractor script, if only one point…

Single Point Attractor – Example 2.1
A common method for form management in parametric modeling systems and contemporary design is to use a concept known as an attractor. This example of a single point attractor has very limited practical use, but the concept can be adapted to more complex situations with multiple point attractors and curve attractors, which I’ll show in…
