Creating Interactive 3D PDFs with Acrobat 3D and the Right Hemisphere PDF Publishing Module

Steps 3-7


  1. Change the default Surface Deviation from .5 to .05. This will create more polygons from the CAD solid geometry by increasing the tessellation. This increase of polygons will make the 3D model look better, but will require an extra step of optimization which will be covered later. Click > OK.

Notice that the current 3D scene has 39,190 triangles/polygons. The function of this tool is to reduce the amount of polygons down as low as possible, but retain the visual fidelity of the model. This process will optimize the 3D file to be as small as possible inside the PDF similar to setting the pixel resolution of a 2D raster image.
