## Tutorial 08: Life with Boundaries

Today we will learn about the inclusion of boundaries in your DEC setup. This will be an essential lesson in solving Poisson problems $\Delta u = f$.

## Tutorial 07: Digital Assets and Conformal Mappings

In your next homework, you will have to deal with conformal mappings. To do this, there are a few things we still have to learn.

## Tutorial 06: Entropy and Waves

In today’s tutorial, we will mathematically prove that we will all die and be forgotten and then simulate this. We will then play with waves.

Please check out the download folder and check out the .hip file of this tutorial. It will contain a functional DEC build with a heat flow example. I have noticed that many of you used for loops to build the sparse matrix. The file shows that this is not necessary.

## Tutorial 04: Volumes and Python (Without Snakes)

Hi! In this tutorial, we will learn the fundamentals of volumes and also get started with python coding! That is an incredible amount of fun!

Volumes

The most intuitive 3D mesh to fill up space is to dissect space into many little cubes. Such a box of dissected cells can be placed using the volume node.

Each cell can now carry an attribute. Normal meshes fill up surfaces only but 3D mesh fills up volume.

The Software used for the Homeworks is called Houdini from SideFx. Upon signing up and installing you will be able to use the free version (apprentice) which comes with no drawbacks accept render resolution caps and watermarks.

We recommend installing the 16.5 version of Houdini. This is due to issues with the use of the Python package Scipy in the newest versions. Please head over to this daily build site to install the 16.5 version.

Why Houdini? It is the leading VFX tool and has, has a nice GUI and comes with a lot of tools and has nice rendering.

Here are some of our previous projects done with Houdini.
