// LedRopeTCL is a C++ wrapper around the Total Control Lighting LED rope
|
|
// device driver (TCL.h). This wrapper includes automatic setup of the LED
|
|
// rope and allows the user to use a graphics-state like interface for
|
|
// talking to the rope. A copy of the rope led state is held in this class
|
|
// which makes blending operations easier. After all changes by the user
|
|
// are applied to the rope, the hardware is updated via an explicit Draw()
|
|
// command.
