What You’ll Learn

Houdini’s unique approach to geometry underpins everything you’ll end up doing with it – VFX, direct modelling, procedural modelling, UVs, scene layout – it all starts here. This course is where we begin laying the best foundations for everything ahead.

By the end of this course, you’ll have a deep understanding of:

  • Houdini’s geometry components – points, vertices, primitives, edges and breakpoints
  • How geometry is constructed in Houdini by connecting points
  • The importance and power of vertices in controlling connectivity
  • The concepts, theories and practical uses of Houdini’s primitive types – polygons, nurbs, beziers, meshes, polysoups and quadratic primitives
  • How to easily convert from one primitive type to another – plus when and why you’d want to


This is the first of three courses in the Geometry Essentials Collection, step two on the Houdini Made Easy learning path.

Course Syllabus


Let’s talk details

Section 01

Creating Primitive Objects

There are different ways you can add primitive objects – at the object or geometry level. We’ll explain what that means, and show you how. Then we’ll get a hold of Houdini’s viewport handles, to tackle positioning and sizing and how to use these in combination with a few need-to-know keyboard shortcuts.

Lessons

1. Creating primitive geometry - create at object level vs create in context
2. Using viewport handles to create and size primitive objects

 
2 Tutorials   5 Minutes

Section 02

Geometry Components

As soon as you look at Houdini’s geometry components, you realise it’s different to other applications. Points as well as vertices? What exactly are primitives and why are there so many different types? A geometry point is the same thing as a particle? Don’t worry, we’ll walk you through it.

Lessons

1. Geometry Components Part 01 - Points, Edges, and Primitives
2. Geometry Components Part 02 - Vertices
3. Component Numbers

 
3 Tutorials   23 Minutes

Section 03

Connecting Points

Building geometry in Houdini is all about connecting points – and vertices are the boss. But you’re the CEO (in this metaphorical company analogy), so you need to know how to get those vertices to work for you. Understanding vertices opens up a whole new world of creative flexibility, only possible in Houdini.

Lessons

1. Connecting Points - Curves
2. Disconnecting and Reconnecting Points
3. Vertices Control Connectivity
4. Connecting Points - Particles to Surfaces

 
5 Tutorials   30 Minutes

Section 04

Primitive Types - Polygons

Just like in other applications, but different. You see, polygons in Houdini are curves at the same time as they are surfaces. What? You heard us. Working with open and closed polygons (and converting between them) is really powerful and incredibly versatile. We’ll show you how.

Lessons

1. Closed Curves are also Polygon Surfaces
2. Every Polygon Face is also a Closed Curve
3. Open and Closed Polygons - Unrolling Primitives
4. Open and Closed Primitives Part 02 - Rendering Curves
5. Polygons - Polymodelling tools on polygon curves
6. Polygon options on Primitive objects

 
6 Tutorials   40 Minutes

Section 05

Primitive Types - Nurbs and Beziers

What’s parameterisation? Aside from a difficult word to say quickly. In this section we’re getting down and dirty with parametric curves and surfaces. Many people think it’s all about polygons these days, but understanding this stuff comes in real handy – especially once you get into procedural modelling.

Lessons

1. Nurbs Curves -  Components
2. Nurbs Curves - Order
3. Nurbs Curves - Point Weight
4. Breakpoints and Converting Polygon Curves to Nurbs Curves
5. Parametric space
6. Parameterisation Part 01 - Uniform vs Chord Length
7. Parameterisation Part 02 - Chord Length and Centripetal
8. Bezier Curves Part 01 - Control Vertices
9. Bezier Curves Part 02 - Breakpoints
10. Nurbs and Bezier Surfaces - Cross Section Curves
11. Nurbs & Bezier Surfaces - Parametric Space
12. Nurbs & Bezier Surfaces - Patches. The Limitations of Nurbs and Bezier Surfaces

 
13 Tutorials   1 Hour 10 Minutes

Section 06

Comparing & Converting Nurbs & Polygons

What do you get if you convert a polygon mesh to a nurbs surface? No it’s not a set up for a bad joke, it’s an important question and one we’re going to answer. While we’re at it, let’s talk about Houdini’s unique ability to subdivide and interpolate polygon curves and how it suddenly makes them as flexible as nurbs curves.

Lessons

1. Comparing Nurbs and Bezier Curves to Polygon Curves
2. Using Polygon Curves Like Nurbs Curves - Subdivision & Interpolating Curves
3. Converting Polygon Faces to Nurbs Surfaces
4. Bilinear Mesh

 
4 Tutorials   27 Minutes

Section 07

Primitive Types – Polysoups & Quadratic Primitives

These guys save lives. Well, not quite – but they do save memory and disk space in wildly different ways. One day to deadline, but your scene is so heavy you can barely move? Building a friendship with these fellas could set you free.

"I am not even exaggerating but you sir are the best teacher I have encountered, ever! You have a way of simplifying the complexities of Houdini in a way that no one is doing and for that kudos. Clearly you understand Houdini inside out plus you have a beautiful voice and accent! The course is enjoyable as much as it is educating."

Attributes

Attributes are the blood that flows through Houdini’s veins, carrying data through a geometry network and passing data from one piece of geometry to another. They’re incredibly powerful – they drive particle simulations, carry material information, and allow for all kinds of custom functionality. Attributes allow us to actually see, read and manipulate the raw data that defines our models and effects…
