Errata for the paper "Differentiable Monte Carlo Ray Tracing through Edge Sampling"

The last two lines in Equation (16) in the paper should read:
$$ \nabla_{v_0} \alpha(p, m) = \left(v_1 - p\right) \times \left(m - p\right), \nabla_{v_1} \alpha(p, m) = \left(m - p\right) \times \left(v_0 - p\right) \\ \nabla_p \alpha(p, m) = \left(v_1 - p\right) \times \left(v_0 - p\right) + \left(m - p\right) \times \left(v_1 - p\right) + \left(v_0 - p\right) \times \left(m - p\right) $$ instead of $$ \nabla_{v_0} \alpha(p, m) = v_1 \times m, \nabla_{v_1} \alpha(p, m) = m \times v_0 \\ \nabla_p \alpha(p, m) = \left(v_1 - p\right) \times \left(v_0 - p\right) $$
