Hi all,<br><br>I have an additive levelling function which has the purpose of smoothing out seams between different parts of texture on my mesh. So for each vertex I have a value between say -255 and +255 and I need to interpolate those values for each face (that's what I want to use vtk/opengl for) and then add the generated levelling texture to the original texture. <br>
So my question is, is there a way in vtk to use color values outside the [0,255] range without scaling or clipping them and render the scene to a 16 or 32bit buffer?<br><br>Thanks,<br>Thomas<br>
