I don't think that's right, Deke. DepthToPoints expects 1/z by default, not a normalized input. Same as the output from ScanlineRender.
The tootip of the "invert depth" knob states that as well: "Invert the depth before processing. Useful if the depth is z instead of the expected 1/z" On Wed, Dec 4, 2013 at 2:45 PM, Deke Kincaid <[email protected]> wrote: > 1 is near though there is an invert depth option in depth to points. > > >>Am I wrong? > > Nuke is 32 bit floating point so it shouldn't matter that much as long as > the original image was a float.
