[Plib-users] douts about ssgCameraGetPosition

[Andreia R de A. S. <an...@co...>]

Hi, I'm trying to get the position of the camera with the function 
ssgGetCameraPosition but the values that are returned do not seem
correct.

The value of my camera is:

  static sgCoord cam_inicial = { { 1.0, 0.0, 0.0  }, { 0,0,0 } } ;

the part of my program that gets the position of the camera is:

	sgVec3 pos_camera;
	int xc; int yc; int zc;
	ssgSetCamera ( & cam_inicial) ;
	ssgGetCameraPosition(pos_camera);
	xc = pos_camera [0];
	yc = pos_camera [1];
	zc = pos_camera [2];
	cout<<"camera: "<<xc<<", "<<yc<<", "<<zc<<"."<<endl;

The values should be 1.0, 0.0, 0.0. But the returned values are -1, 0, 0.

I also tried this with the tux example, values don't seem correct either.
Attached is the modified tux example code.

May someone tell me what i'm doing wrong?

thank's
