using bifacailvf with c++

[Ishratsk]

hi,
I am new to this radiance so...
I have some questions regarding with bifacialvf_radiance .
Q. can I use radiance with c++ and how?
Q.can I get source code of gencumulativesky.exe for information about its all functions?
please revert me on these issues as soon as possible.

thank you!!

Hi Ishratsk, You actually are looking at two different programs. Bifacialvf is a view-factor model that does not interact with radiance. This was originally written in C#, and is in the process of being re-written in C for connection to our System Advisor Model program. We do not have a plan to work in C++ at the moment. Bifacial_radiance is a set of Python wrappers to make it easier to work with Radiance. The radiance software is designed to run on its own, from the command line, so anything that you do with bifacial_radiance can be done manually from the command line. The gencumulativesky source code is attached, which provides some details on how it all works.

HI Chris, I have seen that gencumulativesky.cpp file but still I don't understand how python code is using this and radiance. can you please help me more on it. thanks and regards

Ishratsk, The Python software helps to automate the RADIANCE workflow, which can take some effort and weeks of tutorials to really begin to understand. If you would like to truly understand what the Python software is doing (rather than just running it and using the subroutines) you need to understand the underlying RADIANCE software. I am copying an email below that contains several email links to RADIANCE tutorials. In order to fully understand, you should start from zero and only work with RADIANCE (not Python) to run some example scenes and tutorials. There are several good user manuals and online web tutorials to help you out. Please let me know which operating system you are using: PC, Linux or Mac? Much of my Python software is written for PC, so this is what I am familiar with. If your basic question is regarding how gencumulativesky is working, here is the answer: In a typical RADIANCE workflow, you use the command ‘gendaylit’ to create a single hour Perez sky irradiance source, and save it in ‘skies\sky###.rad’. Instead of this single sky file, gencumulativsky will create a full annual combined solar source, and save it in ‘skies\cumulativesky.rad’ along with a second file ‘cumulative.cal’ in the root directory. Then when you use `oconv` to combine your geometry and ground material into your octree, you include the cumulativesky.rad as your irradiance source. Chris Deline National Renewable Energy Laboratory (303) 384-6359 Here is the git repository for the Radiance binaries – select your operating system: Linux, Mac or PC. Radiance was designed for Linux, but I’m using the PC distribution and most of the functionality is present. Some of the tutorials will have to be modified slightly if you’re not running Linux. https://github.com/NREL/Radiance/releases Tutorials and pointers can be found here (Scene 0 tutorial and Alex Jacobs tutorial are particularly helpful) http://www.radiance-online.org/learning/tutorials Software manual files for Radiance are here: http://radsite.lbl.gov/radiance/whatis_comp.html Other useful bookmarks: http://www.jaloxa.eu/resources/radiance/colour_picker.shtml http://radiance-online.org/pipermail/radiance-general/2009-October/006240.html http://www.radiance-online.org/pipermail/radiance-general/2003-October/001056.html If you would like to work off my Python scripts, you’ll need Anaconda V2.7 (NOT 3.5) https://www.continuum.io/downloads Let me know once you are up and running on the basic Radiance tutorials and I can forward my scene files and Anaconda scripts. Good luck! Just take a week going through tutorials and figuring out how things work, and looking through online resources. It’ll start to make some sense eventually.
