The Helios simulation system is a versatile modeling framework that handles tasks such as managing geometry and associated data structures through a C++ API. Plug-ins build off of the Helios core engine, and access the geometry and data via the Helios context. The sytem comes with a visualization plug-in that can produce stunning renderings of model geometry and data with relatively little effort.
I plan on adding a trellised apple tree model to the system. One that is built off a canopy like the image below.
I plan on working off the walnut tree model and build single apple tree function and eventually a canopy builder.
