Dear Radiance Community,

 

This message is about the future of the Radiance software.  Some changes
are in store and we want to inform you of our plans.

 

As you know, Berkeley Lab has been developing Radiance and distributing
Radiance executables at no cost to the public for over 10 years.  The
Radiance source code has been available for academic and non-commercial
use at no charge for many years and several companies have purchased
licenses to distribute Radiance or Radiance-based products commercially.

 

During the last decade, a number of software developers have contributed
code to the Radiance software, complementing the main development
efforts supported at the Berkeley Lab.  At present time, the funding for
Radiance related developments at Berkeley Lab is very limited, but there
is still strong interest by software developers to further enhance the
Radiance software because Radiance remains unique in its ability to
accurately simulate the propagation of light.

 

In investigating alternatives to leverage interest from the Radiance
community with the core code development from Berkeley Lab, we have
decided to make Radiance an "open source" software product.  The goal of
this is to facilitate continuous development of enhanced versions of
Radiance, whether from bug fixes or additional features and
functionality, all of which we anticipate will be contributed by the
larger Radiance development community.

 

Subject to any required approvals from US DOE, we intend to launch
Radiance as an open source product on December 1, 2002. Beginning on
that date, Radiance source code and executables will be available for
download to any party for any use (commercial or non-commercial),
pursuant to an appropriate open source license agreement.  These plans
also apply to the Radiance engine of the Desktop Radiance software and
are considered for other parts of the Desktop Radiance code as well.

 

We believe that this open source initiative represents an exciting step
forward in ensuring Radiance's continued technical development and
widespread adoption.  We welcome your comments to our proposed plan by
June 30.

 

Regards,

 

Kostas Papamichael
