Basic refraction plug-in


We just finished the development of a material plug-in to simulate basic refractive behavior. To test the plug-in we have modeled with Tonatiuh a Campbell-Stokes sunshine recoder.

In the upper part of the video above you can see the Tonatiuh simulation of the functioning of the Campbell-Stokes sunshine recorder in a cloudless day. Because of the polar mounting of the device and the geometric properties of the sphere, direct sunlight is continuously concentrated upon the recording card as the Sun crosses the sky during a cloudless day.

In the lower part of the video above you can see the simulation of the evolution with time of the solar radiation spot incident upon the sunshine recording card.
