sio2CameraRender bug ?

Hello!

I think there is a small bug in sio2RenderCamera. If you try to build a top view (like the one in Blender) camera the transformation matrix is "O" and after the glTransformRender( camera->transform ); everything is fubared
Tested with the following code:

Code:

   camera = glCameraInit("Camera");
   camera->transform->loc->x =  0.0f;
   camera->transform->loc->y =  0.0f;
   camera->transform->loc->z = 10.0f;

   camera->transform->dir->x =  0.0f;
   camera->transform->dir->y =  0.0f;
   camera->transform->dir->z = -1.0f;

Shouldn't be something like:

Code:

   if(camera->transform->dir->y != camera->transform->dir->y)
   {
          // compute camera transform matrix
          ...
        // render matrix
          ...
}
//translate to camera position
        ...

...or something like that... I'm not sure if this is the fix.

Hummm Im aware of this problem but haven't find a fix that can fit in every situation, you'll get the same problem with gluLookAt
