Release version 1.1.5 of Tonatiuh

We just released version 1.1.5 of Tonatiuh. This new release version of Tonatiuh is a minor release of the program. It corrects  memory leaks and other minor program bugs. It also incorporates the following new two main features:

• A tracker suited to simulate the tracking behavior of Fresnel mirrors.
• The automatic sizing of the input scene aperture, i.e., the surface from which the sun rays are cast towards the concentrating system.

In this new release, the Linux 64 bit version of the program incorporates for the first time the self-updating functionality of the program that was incorporated in the 32 bit version of the program few releases ago.

If you are using a 32 bit version of Tonatiuh and you already installed in your computer Tonatiuh release 1.1.4, you do not need to download the installer for the new release of the program, just start Tonaiuh's release 1.1.4, go the the Help menu in the menu bar, click on “Check for updates” option, and follow the instructions that will appear on the screen. Of course, for that to work you have to be connected to Internet.

Although our intentions are to develop and make available to everyone the 64 bit version of Tonatiuh not only for Linux, but also for window and Mac OS X. We are encountering difficulties to compile Tonatiuh in a 64 bit Windows and Mac OS X system, and we cannot advance a date at which these difficulties will be resolved.

In defining the features that have been added to release 1.1.5 of Tonatiuh we have taken into account the suggestions of the users expressed both in Tonatiuh's user group and in the corresponding “Tonatiuh raytracer product ideas page” at Google Moderator
