Hi, I'm using an ortho frustum to draw a map. On the map I'm drawing a kind of range ring / sector pattern, starting from an origin using lines. I want to draw text at the edge of the viewport where the lines intersect with the edge (well, just inside so the text is viewable).
The problem I'm having is I can't quite figure out how to tell where the lines end within the frustum. Any ideas would be welcomed. Picture for context is attached. Thank you!
