If I should once again begin plugin development, this page shall be resurrected. Plugins are available for both Modeler and Layout. All plugins are available for both the Intel and SGI platforms. Impressions, Pointfolio, PointHandles, Mspot and Dspot are now available. Mac versions may be possible in the future.
More information is given in the individual plugin pages accessed via the links below.
For all the plugins, I strongly encourage you to test drive the trial versions on your system first to see how they perform, before making a purchase. All plugins are subject to a legal disclaimer standard to the software industry. Basically, when translated to English, it seems to say that nothing is guaranteed, there may be bugs, it may not work, it may do damage, you agree to just take your chances and not complain.
