how can I project a 3dpoint correctly when its z is negative?
I would want to visualize correctly
a polygon also when is behind the observer
es:this this example produces an incorrect result.
Distance=2.56f // Distance of the observer
x=-0.5f // 3d x
y=-0.5f // 3d y
z=-2.50f // 3d z
Inverse=1.0f/(z+Distance); // reciprocal
Xp=(x*Distance)Inverse; //x projected
YP=(yDistance)*Inverse; //y projected
thanks in advance
