I want to use the billboard function to draw some wind symbols and arrow symbols, as follows:

However, when the perspective changes, the direction of the billboard also changes, resulting in the wrong drawing direction.  
I try to set the material function of plane, but the size of plane is absolute, and the size of symbols cannot be guaranteed to be consistent when scaling occurs. Is there any way to realize it?
