[JAVA3D] MAP

[Tria]

Hi...   I want to make a rotating globe with texture on it, and if I click on one continent, it will display pop up text, change that continent's color and open another image. But I don't know much about Java3D.. Please check this step : 1. Get trianglearray from the image 2. Create object for each triangle 3, If user clicks mouse on one point, pick the closest triangle 4. Find if that triangle is a part of one active area 5. If yes, get information from the active area 6. Display text on it   Please tell me whether I'm in a correct path or not. The step no. 4 is still not clear for me actually. I plan to put information about active areas in one file which contains coordinates (in polygon shape) for each active area. I want to ensure several things : 1. What is actually the result of TriangleArray ? If I have a world map with no country boundaries, just continents, will it bring me to all those continents? 2. Can I pick the triangle object?   And if somebody here can give me advice to find out how to give color to one area, I would really appreciate it.   Thanks...I'm waiting for your comments.   Regards, Tria
