when updating the Transforms for the plane geometry you also need to
translate it, the Quaternion only describes the rotation, but if the
plane does not contain the origin a separate translation is necessary:
Matrix rotMat;
Vec4f v1(0.f, 0.f, -1.f, 0.f);
Quaternion q(v1, data._equation);
rotMat.setTransform(q);
Matrix mat;
Vec3f v2(0.0f, 0.0f, data._equation[3]);
mat.setTranslate(v2);
mat.multLeft(rotMat);

hm, let me know if the above fixes the problem as well.

ok, will see if we can find it.
