Erd\\H{o}s obtained a near optimal bound of $O(n^{r-1/t^{r-1}})$ for general hypergraphs. In recent years, several works obtained improved bounds under various algebraic assumptions -- e.g., if the hypergraph is semialgebraic.\n  In this paper we study the problem in a geometric setting -- for $r$-partite intersection hypergraphs of families of geometric objects.
