Point counting is a technique used for estimate the composition of a sample. We developed an interactive application designed to facilitate the point counting process through visual computing; this application could be useful in any domain in which the sample image can be digitized. Additionally, we provide other visual analysis tools showing how the application can benefit from the combination of these concepts and the techniques coming from Information Visualization. We utilize the point counting technique on petrographic thin section images in order to perform modal analyses of rocks, but it could be used on many other types of samples in order to estimate their composition.
