About: These digital art 3D plant models were created by an interdisciplinary team of artists and scientists. Dr. Maria C. R. Harrington, Dr. John W. Wenzel, Bonnie Isaac, Chris Jones, and Zachary Bledsoe. The content created for the Appalachian forest resulted from several iterations. The original models were constructed for a Ph.D. dissertation, The Virtual Trillium Trail, then revised in a collaboration between The Harrington Lab at the University of Central Florida and Powdermill Nature Reserve at the Carnegie Museum of Natural History. The Epic MegaGrant funded the improvement of the models for use here and by the community. Inquiries to Dr. Harrington for collaborations are welcome.
