This "little" tutorial will go through the process of creating fins and fin shapes using curves and surfaces in Maya. I found this method to be the most "accurate"while building out the spiny shapes of fins in my current project, and thought I'd share my process. The tutorial below is broken down into three parts and will cover the basics of working with Curves in Maya. A. Building the Main Shape B. Creating the Spines C. Lofting Fin Shapes I will be diving into detail about certain tools in Maya. In this tutorial, I will go over using Live surfaces, converting edges to curves, lofting surfaces, converting nurbs to polygons, extrusions and moving constraints like snap to curve and snap to vertex. A. Building The Main Shape. Create a base curve . The base curve should match the center line of your mesh. This will define where the fin shape will start. If you have a mesh that is already topologized with a clean center line, extracting a curve f...
