Vertex World Position With Offset

Trying to offset vertex positions based upon their normal, similar to how I've seen it done in outline shaders:

but I need to also need the world position of the vertex with this offset. Can anyone help?

Thanks

 

To translate the position from object space to world space you just have to multiply it with the correct matrix:

Code (CSharp):

1. mul(unity_ObjectToWorld, vertexPosition);

Does this answer your question?

 

I need the world space position with the vertices offset a small amount in their normal direction.
