Features:

• 15 AR/VR photorealistic, low-polygon plants
• Individual variations, LODs, wind and light effects, all made using photographs taken in the wild
• 78 unique meshes for use in Central Florida landscapes
• Editable wind material with leaf rustle
• Subsurface scattering maps for light transparency and reflection on leaf surfaces
• 6 ground materials for use in landscape painting and some weeds for ground surface noise
• 1 landscape for large-scale foliage painting (recommending brush size 4000)
• Preset foliage densities for quickly painting foliage on large landscapes
• 1 example natural community/ecosystem created from plant inventory and plant distribution GIS data for Central Florida

About: These digital art 3D plant models were created by an interdisciplinary team of artists and scientists. Dr. Maria C. R. Harrington, Dr. Patrick Bohlen, Chris Jones, Zachary Bledsoe, Jennifer Elliott, Ray Jarrett, Amanda Lindsay, and John Guziejka. The content created for the environment was initiated to support a research investigation of beauty as information and an emotionally salient trigger used in design studies on immersive informal learning. The Virtual UCF Arboretum project is an augmented reality (AR) and virtual reality (VR) collaboration between The Harrington Lab in the Nicholson School of Communication and Media and the UCF Arboretum in the Department of Biology and the Landscape and Natural Resources, in the College of Sciences, at the University of Central Florida. The Epic MegaGrant funded the improvement of the models for use here and by the community.
