In this activity, we will discover how to realize holograms starting from the simulations of a few astrophysical objects, used by researchers in order to analyze physical, chemical, and morphological properties of the phenomenon they want to study. In order to do that, we will need a tool to record the display of our computer – we have used QuickTime, but you can use many other software, such as for example OBS – and Adobe Premiere Pro, a video-editing program. In order to start, we should select one of the 3D models publishedLEGGI TUTTO

On this page, we are showing interactive 3-D models reproducing some of the volumes stored on the shelves of the Historical Archive of INAF Astronomical Observatory of Palermo. In order to reproduce these objects, we used the technique of texturing, a methodology of graphic design, with which a primitive shape modelled in 3D is added to a texture taken by object scans, or by high-resolution photography. For the texturing process, we used black-and-white photos and volume scans. The images obtained were processed with Photoshop and textures were uploaded and mapped usingLEGGI TUTTO

On this page, we are showing the interactive 3D models which reproduce a few objects kept in the Museum of INAF Astronomical Observatory of Palermo. The technique used to reproduce these objects is photogrammetry: an image-capturing method that, starting from simple pictures taken by a digital camera allows you to create a tridimensional model. This simple process fits the logic of image-based modelling, namely 3D modelling based upon images and rendering methods starting from 2D pictures. First of all, place the object at the centre of a room (if it is large), orLEGGI TUTTO
