HARD SURFACE MODELLING IN MAYA
Understanding the correct way to create your 3D structures is vital to the later parts of the production process, such as UV mapping, texturing and animation. In these series of tutorials you will learn about hard surface modelling
By the end of the series of tutorials you should be able to:
Understand the difference between hard surface models and organic models
Understand the importance of Quad modelling
Be able to create a hard surface model in Maya
Be able to research IFUs, marketing material etc and create a hard surface model of a surgical tool
Be able to take reference photos of a tool and create a hard surface model of a surgical tool
Be able to rig a hard surface model so that it’s animation ready
What is hard surface modelling?
“When it comes to 3D modeling, your models will fall under one of these two categories: organic and hard surface. No matter what you’re creating in your 3D application, it’s either going to be a hard surface or organic mesh. This sounds pretty straightforward, right? Just two different categories. However, these two classes of models bring with it countless different explanations and distinctions...”
WHERE DO WE USE HARD SURFACE MODELLING WITHIN OUR INDUSTRY?
Skills for hard surface modelling is a must have for our industry as it can apply to a variety of uses and product offerings:
Medical devices (see Vascutek stent projects)
Surgical tools (either as product showcases or as elements to use within a 3D animation)
Scientific products (like microscopes such as the ONI Nanoimager project)
Quads vs Triangles
We should always aim to create our polygonal models with quads rather than triangles. There are many reasons for this. Read the following articles:
I want you to find two more articles or youtube videos to add to the above reading list.

Maya Hard Surface Modelling Part 1
Yone Santana is a great teacher and his Youtube channel has a lot of fantastic Maya tutorials. For each tutorial, Yone has provided the working files to help you work along with him. I’ve included the files below.

You should probably have a break now
That was a pretty long tutorial!
Low Poly Modeling
It’s always useful to try and build your model with as little polycount as possible and still obtain an organic look and feel. High polycounts increase render times and can bog down, or even crash, your computer. Below are two tutorials that show how you can successfully model a low poly model without it “looking” low-poly.
>> Also take note on how they use image planes to help create the model. This methodology is extremely useful for modelling figures as well as instruments.
How do you model dem shapes?
Low poly modeling can be challenging. Thankfully there are some useful cheat sheets to help you create difficult shapes and still retain a good model when you apply a smooth mesh preview to the model.
The company has collated a bunch of these cheat sheets on our pinterest board. Have this open as a reference whenever you are creating models.
Modeling a Hemostat
You’ll have handy a hemostat to model. Your goal is to create a 3D model of this hemostat.
By the end of this assignment you will have:
Successfully set up a project file
Implemented a good workflow and saved out file versions of your Maya scene files
Taken appropriate photos of the model to help you create an accurate 3D representation
Successfully created a lot poly model of the hemostat that can be opened and closed
Oh my glob, you’ve finished!
Phteven is very happy for you!
