Download Vectrosity Free Unity.
The ultimate professional line-drawing utility, continuously supported since 2010! Find out why Unity users call Vectrosity “great,” “wonderful,” and why buying it “was the smartest move I’ve made for a long time.”
You can do anything from emulating Debug.DrawRay at runtime to full 3D vector graphics games. A comprehensive array of functions makes it easy to draw curves, graphs, dotted lines, selection boxes, arrows, and lots more! Create lines in the editor, or with code.
Comes with complete documentation (one customer said, “your documentation was some of the best documentation I’ve seen for any product anywhere”), and dozens of examples.
Works well on any platform. Complete source code is included, or you can use the .dll (recommended). No garbage is generated except when creating new VectorLine objects.
