H9’s new user interaction offers a more interactive modeling experience for Houdini users. The following lesson shows you how to box-up model a spoon using a number of polymodeling tools. Starting with a reshaped box, you will polyextrude and point edit the shape then subdivide to see more detail. You will then learn how to render your model as a subdivision surface using Mantra’s micropolygon rendering.

As you work through this example you should play particular attention to when you are working at the scene level compared to the geometry level. Generally you position objects at the scene level and shape them at the geometry level. Even the box you first lay down is sized at the geometry level in order to keep your scale values at 1, 1, 1.

You will also learn how you can work with the construction history of the model. Simply by clicking on nodes in the model’s history you invoke a wireframe cage showing that node’s shape and a handle for making changes that ripple through the network. This workflow provides a nice interactive experience as you make changes and refine the shape of the spoon.
