Hi All, I wonder how would I draw a line that is used by Vec6f using fitline

                    Vec6f lineOutput;
                    cv::fitLine(lines, lineOutput, CV_DIST_L2, 0, 0.01, 0.01);

Use doc. Vec6f means a 3d line you would need viz or ogre3d to draw a 3d line

If you want it to work like OpenGL, you would convert your 3D position Vec6f to two 2D coordinates, then use something like Bresenham's line algorithm in 2D to draw a line between the points. I believe that there is a line() function in OpenCV, which can be used as a shortcut.

If you want to draw a line in 3D, you need to draw a cylinder, capped with spheres or circles.
