We introduce the concept of a {\em sensitive $\varepsilon$-approximation} and use it to derive a more efficient algorithm for computing $\varepsilon$-nets. We define and investigate product range spaces, for which we establish sampling theorems analogous to the standard finite VC-dimensional case. This generalizes and simplifies results from previous works. Using these tools, we give a new deterministic algorithm for computing the convex hull of n points in $\mbox{\smallBbb R}^d$. The algorithm is obtained by derandomization of a randomized incremental algorithm, and its running time of O(nlog n + n{\lfloor d/2\rfloor})$ is optimal for any fixed dimension $d\geq 2$.
