Oncall made creative use of the latest technology available in bringing Jurassic Park's dinosaurs to the web. By combining Oncall's Teragon Game Engine software and Shockwave 3D, we were able to create a complete physical simulation including polygonal models, dynamic lighting, and environmental effects – all tuned to animatesmoothly on a wide variety of system configurations. Bone Shop teaches the biomechanical principles of skeletal design by engaging kids to construct and animate their own dinosaur skeletons.
