That can be a good idea, since picking had already looped through the
index buffer already.
But one more thing I would like to ask is that, which is taking this
idea into the next step, how about finding the closest vertices with
the selected vertices. E.g. I had select a vertex, and I would like to
find the other closest vertex that is connected to the selected
vertex. How can I achieve this without looping through the vertex
buffer since it doesn't have picking to find out the indexes.
What I am trying to achieve is that the user can draw a simple line on
the 3D mesh, the drawn line will determine the starting vertex and the
ending vertex, and can select a series of vertices in between that
connect between the start vertex and end vertex.
The 3D mesh is quite dense, often contains 65,000 polygons.
Any help from O3D developers is also highly appreciate as well.
