hello! How I can identify azimuth angle Phi of refelcted angle in 3d . First initial phi angle was given, and further code has changed and now need to caclulate azimuth angle. Here is my code
Thank you in advance

The azimuth angle, denoted by Phi, can be calculated using the given code. The calculation of Phi depends on the plane number (stored in the variable plane).
% Please note that the code assumes the angles are in degrees.
ThetaBar = Theta0;
if plane == 1
PhiBar = 90 + solidIncidentAngle;
elseif plane == 2
PhiBar = 90 + solidIncidentAngle;
elseif plane == 3
PhiBar = 90 + solidIncidentAngle;
elseif plane == 4
PhiBar = -90 + solidIncidentAngle;
elseif plane == 5
PhiBar = 180 + solidIncidentAngle;
else
PhiBar = 180 + solidIncidentAngle;
end
In this code snippet, based on the value of plane, the corresponding ThetaBar and PhiBar values are assigned. ThetaBar represents the polar angle, and PhiBar represents the azimuth angle.
