Hi,

I was experimenting with the Texture Sphere example from the learning section

http://processing.org/learning/topics/texturesphere.html

It shows a globe (world map texture wrapped around sphere)

How would I be able to get an idea for which part of the texture is currently being drawn/on the screen?

For example, say I wanted to have a check in the draw function that was true when a part of the texture (eg. pixels 500 to 550) was being shown.  Or when the mouse is over a certain part of the texture.

I am trying to draw some text on the screen when the user moves the mouse over a country area from the world map.

Thanks,

Aidan.
