A LARGE PUBLIC SCULPTURE PROJECT CREATED DIGITALLY


As an illustration of how a project can proceed I have included photos of a recent project of my own entitled “Herons Landing” which was produced in my studio and foundry. After presenting some traditional pencil drawings and discussing preliminary ideas with my client, I created the sculpture in the Rhino program. The time to produce the virtual sculpture was approximately two weeks. This included some of the learning curve in regard to the program, as I was relatively new to it. When the 3-D drawings were completed, the file was then sent to a nearby firm in Vancouver, B.C. Canada. The company specializes in cutting foam for movie sets using large CNC machines.


The project I made was a 25 ft bronze sculpture; the portion I created on the computer was approximately 12 ft high and 9 ft wide.


After cutting, the Styrofoam positive was coated with a spray-on vinyl. This coating made the surface stronger as I was using expanded polystyrene and also allowed me to finish the somewhat rough surface, using standard polyester auto body filler. Care must be taken not to use fillers or paints which might act as solvents to the Styrofoam. Not only Styrofoam can be shaped. Quite a few materials can be cut with the CNC machine including high density foam, plaster and even marble and granite. Once the surface was finished
