My son, Leighton, took my 2D Xara drawing of Excalibur and converted it to 3D using Blender (excellent free 3D software).
To do this he imported the graphic, created a flat 3D model to match it, and then extruded it appropriately. After touching it up, he mapped my graphic to the proper faces of the 3D mesh, added lighting effects, bump mapping, etc, and then rendered it.
Here it is! Pretty cool, huh? And I didn’t even ask him! We’ve also decided that he can use it in his Wolf’s Bard video game of my daughter’s book. Consider it a cameo appearance!
