We wish you a merry Christmas, peaceful holidays and a happy New Year!
While we too keep our offices closed until 2009-January-05, we made great progress with the continued development of the Ca3D-Engine in the last few weeks, and expect to finish some important changes early in the new year (in fact, Carsten continues work over the holidays from his home office ).
Over the past few weeks, we frequently got inquiries like
The answer is: Hardly at all. We carefully considered the license of each external library before it was integrated for use with the Ca3D-Engine: You can develop your new product with the Ca3D-Engine, keep the external libraries in as-is, and still keep your source code closed. You have to mention all the libraries in your documentation, but we have prepared complete ready-to-use lists for your convenience.
A detailed list of the external libraries employed by the Ca3D-Engine is given here.
In order to make sure that our licensees can actually employ the external libraries without being surprised by additional licensing issues later, we spent the past few weeks reviewing each and every license again, verifying the details. This was and is tedious work, and it turned out that we had to make a few chances regarding some libraries in a few occasions. Good news is that the Ca3D-Engine source code is organized in a highly modular fashion, and so replacing one library with another is never a problem.
In many cases we even already provide the Ca3D-Engine with several alternatives for the same task, so that you can easily choose according to your own preferences (e.g. prefer FMOD or OpenAL? prefer OpenGL or DirectX? prefer Bullet or PhysX? ...), usually with little or no additional work involved.
It turned out that for licensing issues, we had to provide another .zip file decompressor library, and an alternative to the SOAR terrain algorithm when the use is commercial. You can still use the original algorithms at the cost of arranging extra licenses with the respective authors, but this is not required at all and purely optional.
As it is our philosophy to provide you in the Ca3D-Engine a convenient, out-of-the-box, no-extra-efforts-required, great developers package, we're currently adding additional implementations to the above mentioned libraries, e.g. the great SOAR terrain rendering implementation by Andras Balogh.
This important kind of work will be completed very soon, in early January, and we're looking forward to resume the development of new features for the Ca3D-Engine. After all, there is an exciting set of new features in the queue, only waiting to be finished!!
