Hey there! Want to create your very own 3D model viewer? Well, you're in luck! With just a little bit of JSON and JavaScript, you'll be able to bring your 3D models to life. Here's how to do it: First, you'll need to have a 3D model in a format like .obj or .fbx. Once you have your model ready, you can use a JSON file to store the necessary data for the viewer. In the JSON file, you can store information such as the model's path, scaling, rotation, and any additional properties you want to include. Next, you can use JavaScript to parse the JSON data and render the 3D model in a web browser using a library like Three.js. With Three.js, you can create a scene, add lighting, and display the 3D model with just a few lines of code. Finally, you can add interactivity to the viewer by allowing users to rotate, zoom, and pan the 3D model. You can achieve this by capturing user input through mouse and touch events, and then updating the model's position and orientation accordingly. And there you have it! With the power of JSON and JavaScript, you can create your very own 3D model viewer. Give it a try and let your creativity shine!
