Introduction to Surfaces
Meshes / Surfaces / Boundary Representations
A mesh is a collection of triangles and quadrilaterals. It is defined internally as a list of vertices (points) and faces (each face connects either three or four vertices).
A surface consists of a single smooth area but may have custom edges. If a surface is just a deformed rectangle and it has no custom edges, it is called an 'untrimmed' surface. Surfaces with custom edges or holes punched into it is called a 'trimmed' surface.
A Boundary Representation (brep) is one or more surfaces joined together. If a brep only contains a single face, then it is the same thing as a surface. For surfaces to be joined together into a brep, they need to share some of their edges.
Geometry refers to all types of geometry supported by core Grasshopper, this includes meshes, surfaces, and breps, but it also includes boxes, curves, lines, circles, points, etc.

Post a slide with your reading reflections to the shared google slide deck by 6 PM Wed April 13th.
Gannon presents a system for CAD via direct manipulation on the object of interest (the human body in this case). Reflecting on your last two weeks of working with standard CNC hardware (the 3D printer), and CAD software (Rhino/Grasshopper) reflect on the opportunities of Gannon’s approach with regards to design and fabrication expressiveness.
