Hi,

Is there a way to get old school flat shading when using stage3d? Seems like the opengl smooths everything out.

Thanks

Ben

Just ensure your faces are not sharing normals.
or run the Explode class on your mesh(es)

Thanks for the quick reply.

Ah yes that works. The only issue is that when I manipulate the Vertex data the shape breaks up.

Thanks

Ben

This is the non exploded version.

I’m looking for something like this:

1) Create a sphere:Mesh;
2) Move its vertices according to your wishes
3) Explode.apply(sphere);

If you want a sphere not to destruct, use Weld.apply(sphere) before new moving of vertices.

Thanks I’ll try this.

One of the issues is that I’m having to load the geodesic sphere as an .obj rather than create it. The geodesic primitive isn’t available for away3d 4, hence this post viewthread/2255/

I ran into a similar issue exporting an .obj from Blender and choosing to ‘Include Normals’ fixed it for me.

@highrise what you want to achieve can be done in both “exploded” or “welded” state. The problem (shape breaks) is caused by the way you loop over the vertices for your updates. In welded case, you probably need only to loop over the vertices, alter and update, while in “exploded” case, you need to ensure that vertices sharing same original state value get the same update value (probably a direction by a factor) and only once. In welded state, even if your update value would be wrong (not saying it is) the mesh surface would remain “connected”. (assuming it was connected in original state)

Many thanks for this very useful hint. That did it for me.

Thanks for the posts. I ended up Exloding a loaded .obj. Storing all of the verticles that are effectively the same point in a single Vector3D, I could then manipulate these points without the models breaking up. Sorry I don’t have the 3D jargon but happy to post code if it helps.

Thanks

Ben
