Configuring camera

Hi All,

I’m trying to configure my opengl camera in order to reach a user experience like I was sitting in car driving through the city.

However when I reach 60º (pitch) of elevation the roads with z = 0 dissapear and I only see the 3D building.

This have to do we far and near planes clipping ?

Thanks you all,

Victor

Hi Victor,

Probably that is the problem… Wich z clipping values are you using?

Hi,

I’m using as near plane 1.0 and far plane is dynamic depending the elevation but it’s never bigger than 500.

Just miss the z clipping , what it is ?

BR,

Victor

The clipping is what defines what part of the world you are going to see…

Try to decrease a bit the near plane, although that’s not a good thing to do, but try it…

If it doesn’t work I don’t know what else you can do :o

Keep in mind that zNear should never be <=0.0 !

It looks like pifall #3 :

Be sure to apply rotations and translations to modelview matrix, not projection matrix.
