Well thank you Shayne, I understand now, my problem is supposed to be much simplier than handling a *collision detection. *so don't bother yourself with my code snippet, it is just newbie attempt have a nice day* ** * *--* *Mohamed ALJI* Élève ingénieur en Informatique troisième année à

okey, having loaded a 3d model like this image [image: Aqua-Table-by-Zaha-Hadid-for-Established-Sons-1.jpg] I would like to find a way to compute the bottom point of this object ? Until now I don't know, I thoug *--* *Mohamed ALJI* Élève ingénieur en Informatique troisième année à

Hello, Please I am a little bit stucked here ...I would like to caclculate the coordinates (Vec3d) of the bottom point following the Z axe of a model. how I am supposed to do that ??!! I'm trying to compute the intersection between the model and a Plane located at the model boundingBox.zMin, but
