title: threejs selecting different parts of a mesh
body: <p>I'm using THREE.js. I have a model of a human that I want to be able to select different portions of. For example, if you click on one of the legs a particular action will be executed. My original idea was to split the model up into separate meshes and then use raytracing to determine which object was selected. But now when i render the scene, the shading along the edges of each mesh doesn't blend with adjoining meshes. This leaves ragged looking lines across the model between selectable portions. Is there a way to blend the shading between the mesh pieces I've created? Or is there a better way to select part of a mesh other than creating separate meshes? I have some programming experience, but this is the first time I've tried to use three.js. Any insight would be greatly appreciated.</p>
