Section 28.5 Asymptote Links
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 27.1.3) and request this feature through a publisher switch, then each image in an electronic PDF (Section 28.1) will be a link to the HTML version. See Subsection 40.3.5 for the specifics of this entry. This feature is off by default.
