The second step to share your 3D graphics online is to optimize your files for the web. This means reducing the file size and complexity while preserving the quality and detail. Optimizing your files will make them load faster, use less bandwidth, and look better on different devices and browsers. To achieve this, you can use compression tools like Blender, Meshlab, or Draco to compress your files and convert them to different formats like glTF, FBX, or OBJ. Additionally, you can simplify your geometry with tools like Blender, Meshlab, or ZBrush to reduce the number of polygons, vertices, and edges in your models. Furthermore, you can optimize your textures with Photoshop, GIMP, or Substance Painter to reduce their size and resolution. However, be careful not to lose too much detail or quality when simplifying your geometry or optimizing your textures as this could slow down loading time.
