RE: GRAPH 3D v2.42 (Updated 16-DEC-2014)
Here's a slight update to the current beta (v2.421)

I've tried to also implement panning with two-finger gestures, but there seems to be a bug with MOUSE() not properly updating coordinates sometimes. It usually happens when you do a pinch zoom gesture followed by holding your fingers a fixed distance and moving them in tandem.

Anyway, you can choose to disable panning with the setup screen.

Errata (20-DEC-2014): In the g3D_recolor function, insert the following two lines before the "else" statement toward the bottom of the code block.

Code:
    ptdef:=ptdefs(fsel); // <-- add this line
    Zvals:=zvals(fsel); // <-- and this line

  else
    zColor:=makemat(g3D_zcolor(I,J),grid3D+1,grid3D+1);
    ptdef:=makelist(g3D_makeptdef((X-1) mod (grid3D+1),IP((X+grid3D)/(grid3D+1))),X,1,(grid3D+1)^2);
    ptdef:=concat(ptdef,corners);
  end;


There are two known issues. While "spinning" the graph (via a quick single-finger swipe), tapping on the screen may make the rotation "jump." Normally, using the mouse code would fix this issue, but sometimes the MOUSE() command returns the wrong code (e.g. #0h or #7h during a single-finger dragging instead of #2h). The other issue is that sometimes panning/zooming may misbehave because again the MOUSE() command is misbehaving (sometimes it doesn't update both mouse coords when both fingers are held down). So both MOUSE() and WAIT(-1) have their issues (and I suspect they are related).

The way the mouse motion was implemented was to mimic grabbing onto the graph and actually rotating it. I like to tap on a "corner" of the bounding box and move it. The mouse auto adjusts for inversion unlike with the keyboard rotation.
