[openvrml-develop] Proximity sensor problem

[Javier T. <jt...@ud...>]

  Hello all,

  I am using OpenVRML 0.11.1 and I have detected a problem with the proxi=
mity sensors.
Sometimes the camera seems to go in and out of the sensor while it is com=
pletely inside.
The "inside" condition in the VrmlNodeProximitySensor::render method is c=
omputed
with the position of the camera obtained with a call to ViewerOpenGL::get=
Position()

  What I have observed is that the getPosition() method computes the posi=
tion of the
camera from the OpenGL matrices calling gluUnproject()

  The weird thing here is that while the position of the camera doesn't m=
ove, it only
rotates, the values of x, y and z returned by getPosition are different! =
Also, this values
are different from the position of the camera I establish in my program.

  Has anybody noticed this?  What could be the problem?

  Thanks in advance
