I want to render a figure from an orthographic camera at about a 30 degree angle. I want the rendered image to be a certain height in pixels, and I want the part of the scene it contains to stay the same height (in other words, when you look through the camera, I don’t want the height of the visible field to change).
When I modify the width of the image in pixels, if the width is greater than the height (which again, I want to be constant), the height of the viewable area decreases as the width increases. Say I change my width to twice the height — now you can only see of my figure vertically! The height stays the same, though, when the width is less than it.
Is there any way to sort of clamp the height of what the camera sees?
You probably want to alter the Aspect Ratio. After changing the width (Size Y), alter Asp X.
Sounds like you would also have to do some arithmetic in between.
Example -
Set the X and Y sizes to 1000. Set the Asp X and Asp Y to 3.
Change Size Y to 2000. You then need to double Asp X to retain the square view.
Yep, that’s them. The other option is moving the camera. Is it to be used for an animation? Obviously that could cause trouble if you are rendering for television.
when I type in the x/y size manually it always works, nothing automatically changes.
Are you talking about the camera view? That will change to make the longest side fit & scale the shorter side down.
To them get a whole figure to fit in the tall view area you need to move the camera back or adjust the camera lens smaller (if you’re adjusting the camera lens in degrees, make it bigger). This will allow more area in to the camera.
