Gilles Posted October 28, 2014 Report Share Posted October 28, 2014 Can you explain the calculation applied on both techniques (HSH and PTM) in the specular enhancement mode? I have not found the details of this calculation on papers available about PTM and HSH. Only the principle of the method : Specular enhancement : By capturing the appearance of a diffuse object under varying lighting conditions, per-pixel surface normals can be estimated by finding the lighting direction that maximizes pixel brightness. These normals can be used to relight the surface adding synthetic specular highlights. Thank you, Gilles Link to comment Share on other sites More sharing options...
