VIDI provides a Presenter 3D Plug-in Development Kit that lets programmers and animators with programming skills develop special motion effects that can automatically be added to Presenter 3D. They can select from three programming environments, CodeWarrior, Think C, and Think Pascal. The kit includes instructions and various plug-in examples in all three languages. See the Toolkit press release for more information . The kit is available for free now from the Animators area on VIDI's User Repository at http://www.webnation.com/vidirep/.
