Raytracing with GraXML

1. Write VRML files with GraXMLConverter.sh:

   
   Config.setQuality(9); // or higher
   c.convert("MyFile.xml", "MyFile.wrl");
   

2. Convert written VRML file into POVRay file using VRML2POV converter: vrml2pov MyFile.wrl MyFile.pov
Customise created POVRay file so that it ends with something like this (remove unions on the end too):

camera {
       location <-0.5,-0.7,-1.3>
       look_at <0,0,0>
       direction <0,0,1>
       sky <0,1,0>
       up <0,1,0>
       right <1,0,0>
       angle 45
       }

light_source { <10,10,-10> rgb 4*<1,1,1> }
light_source { <10,-10,10> rgb 2*<1,1,1> }
light_source { <-10,10,10> rgb 1*<1,1,1> }
light_source { <10,10,10> rgb 0.2*<1,1,1> }
light_source { <-10,-10,-10> rgb 0.2*<1,1,1> }
light_source { <10,-10,-10> rgb 0.2*<1,1,1> }
light_source { <-10,10,-10> rgb 0.2*<1,1,1> }
light_source { <-10,-10,10> rgb 0.2*<1,1,1> }

3. Use POVRay to create a photo-realistic picture: povray MyFile.pv. You can customise your povray.ini file so that it looks like this:

   
   Width = 900
   Height = 900
   Bounding_Threshold = 2
   Display=On
   Verbose=On
   Library_Path=/usr/local/share/povray-3.5
   Library_Path=/usr/local/share/povray-3.5/include
   Output_to_File=true
   Output_File_Type=N8
   Quality=9
   Antialias=1
