Hello,I want to consult a question.I want to output the intersection point,but I
could not find the function to output the intersection point.I only find the
function of PP_Depth.Who can tell me, if I want to output the intersection
point,I could choose which function instead of PP_Depth().Thank you for
help.Expecting!

#version unofficial MegaPOV 1.2;
#include "pprocess.inc"
#declare DepthMin=0;
#declare DepthMax=10
global_settings {
  assumed_gamma 1.0
  post_process{
    PP_Depth(DepthMin,DepthMax)
    save_file concat("pp_",output_filename(0))
  }
}

Assuming you are using megapov, it's in the doc:

PP_Init_IPoint_Outputs()

f_output_ipoint_x(x,y)
f_output_ipoint_y(x,y)
f_output_ipoint_z(x,y)

#version unofficial MegaPOV 1.2;
#include "pprocess.inc"

PP_Init_IPoint_Outputs()
global_settings {
  assumed_gamma 1.0
  post_process{
    function { f_output_ipoint_x(x,y) }
    function { f_output_ipoint_y(x,y) }
    function { f_output_ipoint_z(x,y) }
    save_file concat("pp_",output_filename(0))
  }
}
I wrote as above,but something was wrong.Maybe how could I modify it?

Please elaborate a bit more on "something was wrong", as my cristal ball
is still in repair and I got no date for its return.

What is your output format ?
Why didn't you provide a fourth function for alpha ?
How is it "wrong" ?

Did your output filename have drive or directory part in it ? (#debug it ?)
