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 29.1.5) and request this feature through a publisher switch, then each image in an electronic PDF (Section 30.1) will be a link to the HTML version. See Subsection 44.3.10 for the specifics of this entry. This feature is off by default.
