Welcome to the 25th issue of TGIC.
Visual programming languages
enable architects to create algorithms by manipulating graphical elements rather than by entering textual code. When visual programming is applied to design, it results in a modelling approach that we refer to as Visual Dataflow Modelling (VDM). Recently, VDM is becoming increasingly popular within the design community, as it can accelerate the iterative design process, thereby allowing larger numbers of design possibilities to be explored. Modelling in a VDM environment is a bit different compared to explicit modelling. VDM consists of creating dataflow networks using nodes and links. Each node can be thought of as a function performing an action and a link is used to connect the output of one function to the input of another function.
A number of CAD systems now provide VDM interfaces, allowing designers to define form generating procedures without having to resort to scripting or programming. Some of the more popular tools include Grasshopper
for Rhino, Dynamo
for Revit and my all-time favorite SideFX Houdini
In this issue, let’s take a look at a few lesser-known VDM environments that architects can use for accelerated form exploration and data manipulation.
Until next week,
