Drawing 3D curve with varying width
I am trying to draw a curve in 3D in which the width may vary. I am doing something similar to what described in the following tutorial: http://www.merowing.info/2012/04/dra.../#.U1QkTOaSy-T
Meaning, i create quads (and triangles) with the desired width instead of using OpenGL width. The problem is that the triangles are actually in 2D - they are drawn in a specific plane. The width will look different, of course, from different angles.
Am i tackling this problem in the correct way? Is there a good solution for my problem?
