to become a reusable general-purpose tool. For example,
a script for measuring shading effects might have been
originally developed to meet the needs of a particular project,
but because each necessary step has been enacted as a
logical procedure that responds to a given site or design, it
can be easily redeployed in a subsequent project.
IN THE BAZAAR
While computational methods can trace their lineage back to
the dawn of computer-aided design, the recent emergence
of platforms such as Grasshopper and Dynamo has made
these tools much more approachable. The communities
surrounding these platforms often mirror those of opensource software where development follows the Bazaar
model - public and distributed across individuals and
companies - rather than the Cathedral model - closed and
centrally controlled by companies or institutions.
This shift should be of special interest to landscape
architects. The comparatively smaller size of our discipline
limits the commercial incentives to create software
specialised to our needs, leaving us often working with
generic or under-developed tools that do not cater
to distinctly landscape architectural approaches.
Computational design offers a means for us to work around
this shortfall by developing and distributing our own tools.
For example, while software such as Grasshopper provides
many inbuilt and community-authored techniques for
geometric development, these capacities are often implicitly
or explicitly architectonic, ignoring or marginalising the
unique complexities of landscapes. To suit our purposes,
computational design needs to not only provide general
methods for describing and testing formal systems but also
general methods for modelling natural systems as they are
relevant to the design of landscapes.

A RIVER AND SHORELINE. SIMULATIONS OF SURFACE WATER FLOWS IDENTIFY
KEY PATHS WHILE A MODEL PREDICTS SALINITY ACROSS THE RIVER'S MOUTH

SLOPE, SUBSTRATE AND SATURATION LEVELS AT EACH SPATIAL POINT.

These methods...have great
potential to better test our
intuition...
Taking ownership over our tools becomes increasingly
important as design modelling becomes ever-more
complex. If drone-based methods become the norm for
many survey tasks, for example, or if virtual and augmented
reality visualisations become common, these technologies
will need to be adapted to our specific needs. Looking just
at a present example: many software implementations
of Building Information Modeling fall short as tools for
developing landscape architectural features, undermining
the methodology's (and our discipline's) promise of
coordinating collaboration.
TOOLS THAT TEST OUR INTUITION
Within my own work, I'm developing tools that augment
parametric modelling platforms with the capability to help
understand and test how natural systems operate. As in
other disciplines, methods for analysis and simulation have
great potential to better test our intuition or to achieve higher
levels of resolution earlier in the design process without
risking rework.
"GROUNDHOG" FOR GRASSHOPPER
For example, part of the Grasshopper plugin I'm developing
("Groundhog") offers capabilities for modelling surface
water flows. Like most common parametric methods, these
capabilities operate as an extensible kit of parts intended to be
combined. Initially, a single component might run a simulation
of flow paths along a given topography to identify areas where
drainage needs are highest. Taking this as a starting point,
further components can identify catchment areas (based on
