An image described by an <asymptote> element will produce standalone HTML files as part of the convversion to HTML output. For 3D images, these are interactive (rotate, scale). If you set a base URL for your project (Subsection 30.1.4) and request this feature through a publisher switch, then each image in an electronic PDF (Section 31.1) will be a link to the HTML version. See Subsection 45.3.8 for the specifics of this entry. This feature is off by default.
