WinOSi is an Open Source, freeware rendering tool for creating real photo-realistic images by a new algorithm, which I have called 'Iterative Two Pass Optical Simulation Raytracing'.

This algorithm combines the advantages of conventional raytracing and radiosity methods together with stunning optical effects like caustics, color dispersion and global illumination, with an accuracy not found in most rendering applications.
