Hello, I would like to propose the Boost.Tweener library for preliminary submission. The purpose of the Boost.Tweener library is to provide solutions to interpolate the intermediate values between two given values during a time interval. Various easing functions can be applied to control the computation of the intermediate values. I felt the need of such a library while developing games but I have also seen this need in various animation softwares. The library provides the following functionalities: - Interpolation is done on the value of a given variable or using an user-provided callback function, - The interpolated values are computed using a predefined easing function or any user-provided function respecting the contract, - Several tweeners can easily be executed simultaneously or in a row, - The type of the interpolated values are user defined. Please follow this link to download a Zip of the library: http://sourceforge.net/projects/libclaw/files/boost/boost-tweener-rc1.tar.gz... Can you check that the library works as expected or tell me what should be fixed before submitting for review? There are various example programs in the archive. Regards, Julien Jorge
