Houdini videos
The version of Houdini we will be using is the apprentice version 11.
Videos
The first videos to watch are the ones included when you install Houdini. In Houdini, go to the menu, click Help > Start Here. This will open up your browser window, and there will be the various links, including some links to videos. The
"Introduction to Houdini UI" is the place to start.
There are some excellent videos to help you learn Houdini. Many of these videos are for version 9, but if your are using version 11, that is OK - the interface is mostly the same in versions 9 and 10.
Peter Quint has also created some excellent videos to learn Houdini. These videos tend to be a bit easier for beginners, since they don't assume any prior knowledge.
On the Houdini Apprentice blog, there are some good videos to get started:
On the Houdini site there are also some other videos introducing the interface, which is useful for beginners.
And there are also some videos on specific tools:
There are also a set of commercial companies producing videos.
The is a Houdini You Tube channel where the Houdini people regularly uoload videos, oftend highlighting the latest features of the software. So these videos are probably less useful for beginners, but great to see the amazing things that can be dione with Houdini.
Of course there is also some other stuff on YouTube. here are a few:
There are also a bunch of commercial training videos that are not free. See the list of companies here:

Elective (AR5953a) Assignment 1
Assignment 1 for the elective (A5953a) is due in Monday 24th January. You will be asked to prepare a 15 minute presentation, using slides and video captures of Houdini. You need to create an A3 landscape booklet documenting your presentation. The assignment is worth 50% of the grade for the elective.
The task for this assignment is to use Houdini to create a parametric model of 10,000 m2 of residential apartment building. The parametric model will be used to automate the developmental step in the IVP design process. The model does not need to be a detailed model, but should include structural frame, lifts, stair cores, and individual apartment units. Elements like individual stair treads and furniture inside apartments do not need to be modeled (or if they are modeled, need to be highly simplified). When modelling elements like walls, they do not need to be modeled with thickness - a single surface will be sufficient.
You need to think about how to parametrise your model. For example, parameters may include the number of floors, the size of apartment, the floor to ceiling height, the depth of the balconies, the size of the windows, .... etc. Do not just try and maximise the number of parameters - instead, try and choose a small number of parameters that produce meaningful results.
In your presentation, do not focus on one final design. Instead, describe how your parametric model works and what types of design variants it can produce. In order to do this, you need to create a developmental diagram showing the relationship between parameters and design variants. This diagram should show a series of modelling steps, and should show how each step is affected by certain parameters.

Welcome
Welcome to the IVP studio. Here is a recap on what was handed out:
The aim of this studio is to develop an iterative design methodology that consists of creating parametric models and evaluating variants generated by these models. You will be required to use advanced digital tools to develop an optimized design proposal that explores the trade-offs between multiple and conflicting evaluation criteria.
The semester will be split into two parts:
· Elective (AR5953a): “Tools and Techniques for IVP”
o Week 1 to week 4: Mon, Wed and Thu afternoons
Total 12 afternoons.
Total 12 afternoons.
o Week 5: Assignment due, to be completed individually.
· Studio: (AR4104): “IVP Studio”
o Week 5 to week 12: Mon, Wed and Thu afternoons
Total 24 afternoons.
Total 24 afternoons.
o Week 13: Final project due, to be completed in groups of three. All the students in the group will get the same grade.
For the elective, you will be introduced to the conceptual framework that is referred to as Iterative Virtual Prototyping. You will learn how to think about design in a new way. Rather than creating one design, you will be creating a digital process that is capable of automatically generating and evaluating large numbers of design variants. The main tool that you will use is called Houdini, developed by Sidefx. This tool is the most advanced procedural modeling tool that exists today, and you will be using it for both design development and design evaluation. You will also be linking to EnergyPlus and Radiance to run simulations of design performance.
For the studio, you will be working in groups of three, and you will sink or swim (or fly) as a group. You will be required to use the Iterative Virtual Prototyping methodology to develop a complex design proposal (site and brief yet to be determined). For the design, you will need to create a digital process that consists of both design development procedures and design evaluation procedures. For development, you need to explore how to parameterize your design ideas so that the right types of variants can be generated, and for evaluation, you need to identify key performance criteria that you would like to use for comparing design variants. At the final crit, you need to present the methodology used to arrive at the final design.
