Hi everyone, I would like to know is there any way to determine if a cone is intersecting with a (finite)line segment. The cone actually a circle located at P(x,y) with theta degree field of view and radius r. The simple visualization can be found here (sorry i can't post the picture here)

I'm trying to do it in C# but I don't have any idea how to that, so for now this is what I'm doing :

Check if the line segment is intersecting with the circle
If the line segment is intersecting with the circle then I check every single point in the line segment using a function I found here.

But I don't think this is the best way to do it. Does anyone have an idea?

For additional info, I need this function to make some kind of simple vision simulator.

Thanks in advance :)

GLSL check if fragment is on geometry

as seen on Stack Overflow - Search for 'Stack Overflow'
I am currently writing the positions of my geometry to the RGB channels of gl_FragColor and I would like to write 1.0 to the alpha channel if the fragment is part of geometry, and 0.0 if its empty. Is there a simple way to tell if a fragment is geometry or not? Maybe through gl_FragCoord.z? thanks >>> More
