Implicit modelling is a game-changing innovation in geological modelling. Traditionally, geological models are produced using a manual drawing process ( explicit modelling) . Sections are defined, and lithologies, faults and veins are drawn on the sections. Lines are then drawn to connect surfaces across multiple sections. Implicit modelling, on the other hand, allows geologists to spend more time thinking about the geology. Implicit modelling eliminates the laborious legwork by using mathematical tools to derive the model from the data. A mathematical construct is built that can be used to visualise different aspects of the data in 3D. This course will showcase the Micromine 2021 Implicit Modelling module that uses radial basis functions (RBFs) to model grade shells, lithology boundaries, faults or surfaces.
