However, the reconstructed models are usually large, have a lot of outliers and have not a correct topology. For that reason, the algorithms used to interact with them must be fast and robust. In this paper, we present an application that enables the interaction with models reconstructed from medical images. The application uses Marching Cubes to generate triangle soups from the medical images. Then, the user can define models by selecting a set of triangles. Once the models have been defined, the application allows to interact with them. In addition, a detailed collision detection is calculated between the models in the scene in order not only to avoid that models in the scene collide, but also to determine which triangles are overlapping. In addition, the calculation of distances and nearest points provides visual aid when the user is interacting with the models.I.3.8 [Computer Graphics]Applications
