When creating computer graphics for historical visualization, there are a variety of techniques and tools you can use, depending on your goals, skills, and resources. 3D modeling involves creating a digital representation of a physical object or scene using geometric shapes, surfaces, or curves. You can use 3D modeling software, such as Blender, SketchUp, or Maya to create your own 3D models, or access online repositories like Sketchfab, Google Poly, or 3D Warehouse to find and download existing 3D models. 3D scanning is the process of capturing the shape and appearance of an object or scene using a device that emits and records light. Meshroom, Agisoft Metashape, or Autodesk ReCap are some of the commonly used 3D scanning software. Alternatively, you can use online services like Sketchfab, Google Street View, or Google Earth to access and explore 3D scans of historical locations or objects. For 3D rendering, you can use Blender, Unreal Engine, or Unity to create realistic or stylized renderings of your 3D models or scans. Additionally, platforms like Sketchfab, Google Earth Studio, or Cesium enable you to display and share your 3D renderings on the web or in virtual reality. Lastly, 2D graphics involve creating or editing images or videos using pixels, vectors, or shapes. Photoshop, Illustrator, GIMP are some of the popular 2D graphics software used for creating maps, charts, diagrams and illustrations. Alternatively you can use online tools like Canva , Piktochart ,or Infogram to create and share your 2D graphics online in presentations.
