hello.
I implemented a simple 2d drawing sysytem that draws points and lines(for now)
I must implement a picking in 2d for intersection of a mouse click and a point and a line.
Has a sense create a ray for the intersection in 2d?
how i can implement these algorithm?
I also have to consider the modelview matrix and the scale/rotate that i can apply to the document .
there is an example?
thanks.
