Here is my Three.js model that I'm working on:
View the unsmoothed part of the model here
To export the model into a JSON file for use in my Three.js application, I used a plug-in from the Unity asset store. However, the plug-in did not export the smoothing groups, resulting in a lower quality appearance of the model.
Does anyone know of a way to smooth everything out within Three.js?
If you want to implement subdivision in your geometry using Three.js, you can make use of the THREE.SubdivisionModifier. Here's how you can do it:
var modifier = new THREE.SubdivisionModifier(divisions);
// Apply the modifier to your geometry (not mesh).
modifier.modify( geometry );
Please note that this functionality is not built into Three.js by default, so you will need to import it separately. You can download it from here.
UPDATE 1: When a JSON file is loaded, it becomes an Object3D, acting as a container with a specific structure:
To modify the "geometry", you have to access it like this:
modifier.modify( mesh.children[0].children[0].geometry );
You'll need to apply the modifier to each model in your scene, for example:
modifier.modify( mesh.children[0].children[0].geometry );
modifier.modify( mesh.children[0].children[1].geometry );
modifier.modify( mesh.children[0].children[2].geometry );
This process involves opening containers within containers until you reach the geometry data. I hope this explanation clarifies the procedure for you :)
