Half as a learning excercise and half as something useful for the project I'm on, I'm trying to draw some lines on the screen. What I want to draw is a vertical line of variable width that sticks to the cursor as you move it. The vertical line would extend the height of the image.
I'm new to OpenGL but getting around Mu pretty easily. What is the most similar example provided with RV or are there some pointers someone would give to point me in the right direction?
