Large-scale transformation optics — supplementary information

All simulations shown in the paper were performed with our custom ray tracer Dr TIM [1, 2] (Fig. 1). With the instructions provided in this section, the reader should be able to run all simulations described in this paper, shown again in Fig. 2. Further information on how to use Dr TIM can be found in the user guide [3]. Dr TIM runs on any computer capable of running Java programs that require the Java Virtual Machine (JVM) 1.6. To run Dr TIM, download the Java Archive (JAR) file from the supplementary material and open it. Provided Java is correctly installed, Dr TIM should start up and display the window shown in Fig. 1. Two sets of parameters need to be adjusted to repeat our simulations, namely the parameters describing the scene, and the parameters describing the camera. This is outlined below. To render the view with new parameters, press the Render button on Dr TIM’s home screen. Pressing the Edit scene button on Dr TIM’s main screen allows editing of the scene. The basic scene we used to illustrate the pinch-transformation window can
