Release of version 1.1.1 of Tonatiuh

We just released version 1.1.1 of Tonatiuh. This is a minor version of the program. The main characteristic of this release is that it incorporates the most recent versions of all of the program's supporting libraries: Qt, Simage, Coin, SoQt, Marble and Berlkeley DB.

As shown in Figure 1, this release is faster than version 1.0.0. Under Windows, it achieved a 14.1% reduction in the average time it needed to cast 6 million rays while simulating the optical behavior of NREL's Solar Furnace in the three computers in which the program was tested. Under Linux this average time reduction reached 15.6%.

The release fixes several small program bugs and introduces both a new version of the Buie's sunshape plugin and a new version of the spherical rectangle plug-in. It also slightly changes the way the user can use Marble to select a given location on the Earth.

As always, if you find bugs in Tonatiuh or in any of its plug-ins, please, take the time to report those errors using the "Issues" tab in Tonatiuh's website at Googlecode. Furthermore, if you have suggestions on how to improve the program or increase its functionalities, please, let us know, either by adding comments to this post, or better by participating on the corresponding discussion of the Tonatiuh users group.

Best regards. Enjoy!
