Opticalc is a Python library used to generate integrated spectral averages summary values for single glazing and shading layers. It uses https://github.com/LBNL-ETA/pywincalc to perform these calculations. Pywincalc is, in turn, a thin wrapper around the C++ library https://github.com/LBNL-ETA/wincalc. So opticalc wraps pywincalc wraps wincalc. Turtles all the way down.
Opticalc is used primarily by Checkertool V2 as it validates certain products and generate integrated spectral averages summaries.
Opticalc attempts to abstract away the peculiarities of pywincalc,
as well as use standard dataclasses and Enums to describe the type of data needed to calculate
integrated spectral averages summaries. These foundational dataclasses and Enums are stored in a separate library
called py_igsdb_base_data (https://github.com/LBNL-ETA/py_igsdb_base_data) so that they can be accessed directly
by Opticalc and other libraries and applications, like CheckertoolV2.
Here's a simple illustration of the relationship between these application and libraries:
Why not include this logic directly in Pywincalc? Pywincalc is generated programmatically from wincalc and does not have much in the way of custom, Python-based logic and classes that help a user make sense of the types and shapes of data and the nature of various operations. Opticalc serves as a location for this extra Python-based code.
