 | | Simple POV-Ray Question - Perspective —Shaun Sullivan
|
| | | Hi All, I should know this ... what's the trick for turning off "perspective", if you will, so that you can do a straight-on side view? That is, to remove the "vanishing into the horizon" effect? ISO views, is that what it's called? Ugh ... HELP! -s (21 years ago, 23-Jan-04, to lugnet.cad.ray)

| | | | | (...) In the camere code block, uncomment "orthographic." You may have to play with the camera location and look_at, because the camera appears to move when you render in orthographic mode, but that does the trick. Also, higher values for angle (...)

| | | | | (...) Using orthographic does not always work. You can get the same effect by seeing the camera angle to 0.1 Kevin (21 years ago, 23-Jan-04, to lugnet.cad.ray)

| | | | | | (...) Don't you then have to move the camera a ways back to get all your objects in the image compared to larger camera angles? This is what I tend to do, long ways away, small canera angle (anaogous to "telephoto" in real photogs, the images there (...) (21 years ago, 23-Jan-04, to lugnet.cad.ray)

| | | | | | | (...) I've run into this problem, and my caveman-sophistication led me simply to translate the object a little to put it back in line with the look_at coordinates. Even so, I often have to change the "PCT" value to 5 or 10 to accommodate all of my (...) (21 years ago, 23-Jan-04, to lugnet.cad.ray)

|
| | | | | | | | (...) As long as you let L3P calculate the camera distance, the whole model should be visible, and (mostly) fill the frame. I just copied the L3P auto-camera algorithm into LDView, and it works consistently for me with camera angles ranging from 0.1 (...) (21 years ago, 23-Jan-04, to lugnet.cad.ray)

|
| | | | | | | | (...) If you just do a straight "L3P model.dat," then you're right; the whole model fits very nicely in the camera's view (though a little fish-eyed, I find). But if you switch the view to orthographic, the model can appear a bit off-center and (...) (21 years ago, 23-Jan-04, to lugnet.cad.ray)

Here's what I use when I'm rendering parts: camera { orthographic sky -y right -4/3*x location <100,-60,100>*100 look_at <0,20,0> angle 1 } Change the location and look_at to suit your tastes. Note that I multiply the location by 100. I work (...) (21 years ago, 23-Jan-04, to lugnet.cad.ray)
