Curves In Houdini

In this tutorial we examine curves in Houdini. Curves are an essential part of 3D modeling. Houdini has the unique ability to work between NURBS curves and polylines seamlessly. For instance, with NURBS we are able to embed attributes along the parametric curve like UV. We can then easily convert the curves to polylines, maintaining any attributes. We can then use VOPS or VEX based methods for controlling new attributes. In addition these can drive any number of things. This makes it possible to manipulate any attribute we want. This can control things like object instancing, scale along the curve, or any number of other effects. It is also possible to maintain a consistent point count between the two types. Maintaining a point count is imperative to creating good tools that can create objects at a variety of resolutions. Houdini also has the typical curve tools. Lastly, we examine how to set up common operators. For example, common operators are nodes like revolves and other curve based effects, like sweep and carve.

After this one should have a solid understanding of:

  • The Curves tools in Houdini
  • UV attribute on Curves
  • Making shapes with Revolves
  • Extruding along a path correctly
  • Carving with Curves that have UV attributes

Once you have a solid understanding of curves in Houdini you will be able to create numerous effects and tools.
