Hi folks,
We are building a database using an additional texture layer as a height field. I'm finding that the image stored in database is coming across with what appears to be 1bit noise. A constant image of say, 125 / 255 after going through VPB is coming out with some values of 124 / 255. The pattern looks a bit like quantization noise but we are setting --disable-error-diffusion just in case and the target has compression disabled using -RGBA. Does anyone in OSG land have an idea where I can look to see what is causing this? I'm attaching captured images where I've applied the same stretching formula. One is from the rendering of the database and the other is from Mathcad, where I loaded the source image and displayed it with the same stretch. The database image capture shows the "speckles" where as the source image does not. [Source.png] [Subset_VPB_pow10_1000.jpg] -B --- Brad Colbert Renaissance Sciences Corporation (480) 290-3997
