distance

I have a database with Points of Interest that all have an address.

I want to know what is the method/name/call to get all nearby POIs from a given position.

I understand that I need to convert all my addresses to LAT / LON coordinates at least, but my question is:

for a given LAT / LONG how do I get from the database/array what POIs are nearby by distance, for example:

You are here 0,0 nearest POIs in a 2km radius are:

POI A (at 1.1 Km)
POI C (at 1.3 Km)
POI F (at 1.9 Km)

I have no idea what should I look into to get what I want :-(

Any help is greatly appreciated. Thank you

I am currently porting a demo from XNA to DirectX which, as I understand it, both have coordinate systems with different handednesses. What are the things I need to bare in mind when converting between the two? I understand not everything needs to be changed. Also I notice that many of the 3D… >>> More

I'd like to know how to get the rotation matrix for the transformation from one cartesian coordinate system (X,Y,Z) to another one (X',Y',Z'). Both systems are defined with three orthogonal vectors as one would expect. No scaling or translation occurs. I'm using OpenSceneGraph and it offers a Matrix… >>> More
