There are two vertices with z = -10.591118
and one with z = -10.833504
#declare base_02 = mesh2 {
vertex_vectors {
3
<2.952163, 3.632734, -10.591118>,
<1.556791, 3.632964, -10.593109>,
<2.93827, 3.516272, -10.833504>,
}
So it's not completely vertical, which means the intersection point will be
farther back than -10.591118. The z coordinate of the centroid of the
translated triangle lies at -7.67195467, but maybe it's intersecting at one of
the other triangle centers.
