Function ncollide3d::query::time_of_impact

pub fn time_of_impact<N: Real>(
    m1: &Isometry<N>, 
    vel1: &Vector<N>, 
    g1: &dyn Shape<N>, 
    m2: &Isometry<N>, 
    vel2: &Vector<N>, 
    g2: &dyn Shape<N>
) -> Option<N>

Computes the smallest time of impact of two shapes under translational movement.

Returns 0.0 if the objects are touching or penetrating.
