檢視 $ranges (RayTracing) 的原始碼



$totalregion is a required input tag the total regions to set the material parameters.  <br>
This includes the normal rectangular region triangular region and other special shape regions. This command is conflicted with the command [[$totalparameterregion]]
It usually goes with commands  [[$ranges (RayTracing)]] and [[$parameters (RayTracing)]],

For example: <br> 

 $totalregion
 N_region 

 $ranges
 <math>x_{L}</math>  <math>x_{R}</math>  <math> y_{bottom} </math>  <math> y_{top}  </math>  
 <math>x_{L}</math>  <math>x_{R}</math>  <math> y_{bottom} </math>  <math> y_{top}  </math>  
  ...
  ...   total N_region
  ...
  <math>x_{L}</math>  <math>x_{R}</math>  <math> y_{bottom} </math>  <math> y_{top}  </math>   

 $parameters
 <math> n_{r}  </math>  <math> \alpha </math> 
 <math> n_{r}  </math>  <math> \alpha </math> 
 ...
 ...
 <math> n_{r}  </math>  <math> \alpha </math> 

 
  <math> x_{L}</math>  : left range of x  (unit <math> \mu m </math>  !)
  <math> x_{R}</math>  : right range of x  (unit <math> \mu m </math> !)
  <math> y_{bottom} </math> :  bottom range of y (unit <math> \mu m </math> !)
  <math> y_{top}  </math>: top range of y (unit <math> \mu m </math> !)
  <math> n_{r}  </math>: refractive index
  <math> \alpha </math>:  absorption coefficient
