Jan 7, 2011 at 11:23 AM

Is there a way to buy ARTag or ALVAR library??...ARTag library has expired on dec 31 and therefore i can not use the library for my thesis project. For trial version of ALVAR i have only 30 days to use it....

how can I do?

ARTag does not have a license available as long as I know. Are you sure ALVAR non-commercial free version only have 30 days limit? I thought it had 1 year limit.

With basic version of alvar there is one year limit, but when I open my application that uses alvar library it says me:

On the website of alvar I have seen That there is also the 1.5.0 version with these features

  • added licensing system to disable time-bomb
  • refactored capturing system to actually allow for third party plugins
  • added a check that detects the presence of capture plugins and displays an appropriate error message in samples
  • documentation updates
  • fixed build system on Windows Vista
  • fixed bug in UKF implementation
  • fixed MultiMarker implementation to allow marker sets that do not contain id 0
  • fixed bug with distortion initialization in Camera class

we'll add AVLAR 1.5.0 support in the next release. For now, please use ALVAR 1.4.0 since it won't expire for a while.
