   Mesh / Vertex Buffer troubles
  Hey all,I had a quick question on working with meshes. Currently, I am loading in just a square mesh, and am attempting to do some area sampling on the vertices of that mesh to create a simple rippling effect. However, I am confused as to how to access specific vertices, (i.e. vertices[x,y], vertices[x,y+1] etc. ). I am currently calling my mesh->LockVertexBuffer() and retreiving a pointer to the vertex memory from there, but it seems rather arbitrary as to where specific vertices are. Any help in this is greatly appreciated.Regards,- Dave   
  It is up to you to decide what order the vertices go in. If you are not using an index buffer, then the order must be the order that the vertices are rendered.; hi ETFBlade  check this link i think it will solve ur problemhttp://www.gamedev.net/community/forums/topic.asp?topic_id=356321
