3D mouse

Hi guys,

I am tring to understand input information of (grread t) on 3d Mouse.

(defun c:go ()
 (setq check 0)
 (while (= check 0)
 (setq dr (grread t))
   (if (atom (nth 1 dr))
     (progn
(princ (strcat "\n" (rtos (nth 0 dr) 2 0) "-" (rtos (nth 1 dr) 2 0)))
     )
     (progn
(princ (strcat "\n"
  (rtos (nth 0 dr) 2 0)
  ", "
  (rtos (car (nth 1 dr)) 2 0)
  ","
  (rtos (cadr (nth 1 dr)) 2 0)
  ","
  (rtos (caddr (nth 1 dr)) 2 0)
  " "
))
);progn
    );if





 )
)

the result is

2-39

2-95

2-51

2-100

2-120

2-109

2-111

2-118

2-101

2-32

5, 2070,842,0

2-39

2-95

2-51

2-100

2-120

2-109

2-111

2-118

2-101

2-32

 

 

2 is for 3D mouse

5 is for 2D mouse

For now OK

but why (grread t) replays meny times

2-39

2-95

2-51

2-100

2-120

2-109

2-111

2-118

2-101

2-32

?

Does not matter how to twist left/right, move left/right/up/down on this 3D mouse?

2 indicates a keyboard input.

Hi Lee,

I copied one to one content of autocad text screen.You are right that 2 is keyboard input. I am runnig on Win XP/32bit , autocad 2009. The 3D mouse is 3Dconnexion- the simples with two buttons. Else under AutoCad 2009 it is working perfect - zoom, pan, move and so on.

May be (grread) can not read correctly from this device.
