They differ only in the type declarations of their parameters and whether or not they assume a two- or three-dimensional space. PPPPAAAARRRRAAAAMMMMEEEETTTTEEEERRRRSSSS _d_x expects the distance from the x coordinate of the current graphics position to the x coordinate of the new point. _d_y expects the distance from the y coordinate of the current graphics position to the y coordinate of the new point. _d_z expects the distance from the z coordinate of the current graphics position to the z coordinate of the new point. DDDDEEEESSSSCCCCRRRRIIIIPPPPTTTTIIIIOOOONNNN rrrrddddrrrr is the relative version of ddddrrrraaaawwww. It connects the current graphics position and a point, at the specified distance, with a line segment using the current linestyle, linewidth, color (if in depth-cue mode, the depth-cued color is used), and writemask. The system updates the current graphics position to the new point. Do not place routines that invalidate the current graphics position within sequences of relative moves and draws.
