PRESIDENTIAL SEALS

PRESIDENTIAL SEALS

PURPOSE OF THE PROJECT - Creation of relief models of both versions of the presidential seals for holographic imaging. The intention was to create digital models that could be scaled to a variety of sizes and then cut from appropriate materials using a high resolution CNC milling machine.

CLIENT - CROWN HOLO-GRAFX

PROJECT DATE - November, 2002

PROGRAMS USED - FREEFORM V-5 / ARTCAM PRO








		The Freeform model was then imported into Artcam Pro where the final details and text were added.


	Version 1 - begins with the receipt of a “line art” drawing of the desired seal. This drawing is then imported into Freeform and used as a template upon which to begin building the individual parts that make up the final digital model.



			The digital model was then completed to this point using Freeform.




			The digital model was then brought to this stage of completion using Freeform. The various colors are used to identify different sub-assemblies that make up the model.



			The completed Freeform model was then imported into Artcam Pro where final details were added.


Version 2 - “line art” reference drawing



This green model is a medium resolution OBJ mesh version of the Freeform model. The OBJ mesh was then imported into Lightwave where this test rendering was generated. The shadowing under the feathers in the wings is the result of non-planar polygons. This can be eliminated by exporting the OBJ model at a higher resolution.
