Hi,
IIRC TSM is patented (at least in USPTO), so there can be legal issues

Hi Robert,The submission includes a modification version of ViewDependentShadowMap. It implements a shader generator which allows users to change it freely in the ShadowSettings class instead of defining shaders in the ViewDependentShadowMap.cpp. A new setShadowTechniqueHints() is added to integrate and use some shadow techniques (presently there are PSSM, VSM, PSM and PCF filter). Some methods are removed as they are not required anymore because of the appearance of the new setShadowTechniqueHints() interface.Current implementation is still not perfect when handling some large scenes or complex models. I plan to rewrite the VSM and PSM parts to support exponental shadow map (ESM) and trapezoidal shadow map (TSM) later. Also there are quite a few code required to be improved by the community so that this ViewDependentShadowMap could be used in most practical cases in future.Cheers,Wang Rui_______________________________________________
