Visual analysis plays an important role in understanding and evaluating the climate models, their variables, and their outputs because complex processes are required for the tuning of the climate models. Virtual Reality (VR) technologies are effective for 3D visualization and have been recently employed for visual analysis of more various scientific data. However, researchers may have some problematic situations while using VR space depending on user operations and target geometries. Here, we propose an image-based view selection method to solve these situations and understand differences in ocean states between simulations and observations based on shapes of mode water regions. This view selection takes evaluation criteria for shape comparison of mode water regions generated from simulations and observations into account. This paper introduces two example cases applying this view selection and discusses on a degree of shape matching of mode water regions of each case.

The visualization means "to make an invisible thing an visible thing", and "to make an visible thing an easily understandable thing. Widely, a clock which makes time a visible thing, and a speed meter which makes speed of a car an visible thing are a device of the visualization, however, in this book we introduce the image processing of the simulation result for the purpose of the confirmation, evaluation, and transmission of the simulation result. In this book we carefully explain the PC environment and the data conversion process for visualizatoin, the basic knowledge about computer graphics, the setting of visualization methods and their parameters, a role of the visualization in the numerical simulation, and a way of thinking of the visualization in the presentation.
