Trouble! I\'m looking for a way to find the countries within a given range of LAT/LONG coordinates. E.g.:
I need to convert rectangular coordinates to polar coordinates. Can you recommend a library that I can use, I would rather not have to write this myself.
I\'ve created CocosNode, then inserted sprite in this node. I moved node and sprite 开发者_C百科separately. As result node has some coordinate, sprite has another coordinate. I see sprite on the scree
If I think of the x,y coordinate plane, x,y is the common notation for an ordered pair, but if I use a two-dime array I have myArray[row][col] and row is the y and col is the x.Is that backwards or am
I have two sets of Latitude/Longitude coordinates. The first one is the coordinates of an equirectangular panorama picture.
This is not really a functional problem I\'m having but more a strategic question. I am new to 3D-programming and when looking at tutorials and examples I recon that the coordinates are usually betwee
I\'m trying to come up with an iterative function that generates xyz coordinates for a hexagonal grid. With a starting hex position (say 0,0,0 for simplicity), I want to calculate the coordinates for
I get some GPS coordinates from Google Maps and I need to find the distance between them using Objective C. I have implemented the formula but I get results that are way to big.
I need a 2D coordinate system to which renders a user space coordinate system to swing components on the screen. Now that is exactly what Java2D does. But what I need further is to move the relative p
i dont get how to translate the coordinates of the iphone. if i make a single touch i get the coordinate.
