It's the osgintersection example so... Could they be the intersections
points

Go have a look at the code, and the headers.

So what do you get from the output of "osgintersection"? For example if I run 
"osgintersection cow.osg" I get:
Intersection
Computing LineOfSight
Completed in 0.096953
  point 0.776125 0.815986 0
  point 0.776125 -1.683 0
  point 0.839681 0.791811 0
  point 0.839681 -1.65035 0
  point 0.903236 0.767635 0
  point 0.903236 -1.63128 0
  point 0.966792 0.74346 0

So what are the points?

[osg-users] Help: Is there an osg example with ray tracing?

2012-01-13 Thread wang shuiying 

Hello,

I simulate a laser sensor with shader using osg, and want to compare it 
with simulated laser sensor using ray tracing technique. So is there a 
ray tracing example of osg in such application?


Thank you in advance!

Shuiying,

I would start by looking at the osgintersection example, in
particular, the LineSegmentIntersector to see if that will help you.
