Hello everyone, I have an issue, let me explain a little about my project, I have high quality 3d historical scan data and have rendered about 50 images of the object, all with different sources of light. I have also done the same thing with a black sphere. My plan was do create a project using the black ball and then using that .lp file to import my object images. My issue is after i've converted my rendered images to DNG, then back into JPG, I am not able to import the picture. I was trying to select multiple images but it would not let me do that. I have also tried updating Java. Any Help? It would be very helpfull.
After the coefficients are found for Hemispherical Harmonics, how does RTIBuilder determine the direction of the surface normal? Does the program assume the surface is diffuse and look for the maximal lighting direction? I have seen multiple articles (Manfredi et. al.) that state that HSH more precisely determines surface normal direction, but neither those articles nor their references seem to point to how the surface normals are actually calculated. Unlike PTM, there are potentially multiple places where the gradient could be zero and with 16 coefficients, those locations are not easily solved for. Thanks for any assistance!
