Hi, I'm trying to render a model using the following commandline in L3P: C:\L3P\L3P.EXE F:\trainpos\M4564a_.dat F:\M4564a_2.pov -cg0,90,0 -b1.000,1.000,1.000 -q3 -lgeo -o And with only this model (I rendered more with the same parameters) I get the (...) (23 years ago, 24-Dec-01, to lugnet.cad.ray)

(...) No, POV-Ray's rendering engine doesn't really care what the dimensions of your image are. It only cares about what you tell it the aspect ratio is. If you render with a default camera (4/3 ratio) to a square output image, you'll get an image (...) (23 years ago, 20-Dec-01, to lugnet.publish, lugnet.general, lugnet.cad.ray)

(...) No, Bram is 100% correct -- the resulting image is distorted unless I account for the proportions of the image POV expects to render. -- Hop-Frog (23 years ago, 20-Dec-01, to lugnet.publish, lugnet.general, lugnet.cad.ray)

(...) You may want to make it 6400x4800 or 4800x3600 so that the render isn't distorted. If you want a square picture, you will need to modify the camera object so that it renders to a square aspect ratio. Millions of pixels also take a while to (...)

Steve, I can explain better using black and white printers; for color, just add four times the explanation. For a monochrome printer, there is a tradeoff between lpi and grayscales. If you have a 600 dpi printer, and you chose a 600 lpi screen, you (...) (23 years ago, 19-Dec-01, to lugnet.publish, lugnet.general, lugnet.cad.ray)
