<p>Thanks! A very simple but great way to estimate mean curvatures@NathanReed answer.
For my case, I also need an estimate of triangular mesh curvature, and I support this is what i was looking for.
However, could you please show me (or any recommended literature) how is the following equation derived?</p>

<p>$$\frac{(n_1 - n_0).(p_1 - p_0)}{||p_1 - p_0||^2}$$</p>

I've extended my original answer with more explanation about the derivation of the formula. I think this question can be closed.
