Starting with version 1.7, PDF introduces the capability for collections of 3D objects, such as those used by CAD formats, to be embedded in PDF files. Such collections are called 3D models, and PDF refers to them as 3D Artwork. In PDF documents, 3D Artwork is represented by 3D annotations stored in Universal 3D (U3D) format.
The ImageGear.Formats.PDF namespace allows the following 3D features:
- 3D content can be rendered within a page.
- Multiple instances of 3D data can appear within a page or document.
- Specific views of 3D artwork can be available, including a default view that is displayed initially and other views that can be selected.
- Users can rotate and move 3D data, enabling them to examine complex objects from any angle or orientation.
