I was trying to separate the total radiation into direct radiation and diffuse radiation.
I did a single hour radiation simulation. And the some parts of sunlight were blocked by the louvers.
I have 400 test points. Thus, some of points will result 0 radiation, and others will result the same value of radiation. Because I checked “removeDiffuse_” on selected sky matrix component, by computing the angle between normal vectors of test points and the sun vector, the test points will have same value of factored direct radiation at the hour.
But, my assumption was wrong. As you see my sceenshot and the attached GH file, it shows different values of radiation on my test points. It looks like that the diffused radiation is included on my result.
Am I wrong? How can I calculate the direct radiation only on LadyBug?
Thanks for your answers.
