distance

Hi,

I have a line segment AB between two WGS84 coordinates on the earth's surface (or, alternatively, on an ellipsoid), and need to calculate the distance between a point P and the point nearest to P that is on line segment AB. How can I do this?

Any help is greatly appreciated.

Regards, Jochen

PHP Library: Calculate a bounding box for a given lat/lng location

I'm looking for a PHP Library / PHP Script that allows me to calculate an accurate bounding box for a given center point (lat/lon). Using an ellipsoid formula (f.ex. WGS84) would be great. I know, there have to be a library but I'm not able to find one. >>> More

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
