Aspect Ratio
Together the right (width) and up (height) vectors define the aspect ratio of the resulting image.
A Change in version 3.8 redefines how the right vector default is derived. Previously a fixed value, it is now a calculated value that is based on the image width and height specified at render time. As usual, the image width and height can be specified from either the pull down menu available in GUI versions ONLY or the +Wn and +Hn command-line options available to ALL versions. This behavior is conditional upon the last effective #version directive before the camera definition. The default up vector remains as <0,1,0>.
To retain legacy behavior see the example below:
#version X.y; // X.y is a version less than 3.8
camera {
location <3,5,-10>
look_at <0,2,1>
}
Angles
Might want to re-mention in the Angles section that the default angle is ~67.380. SharkD 23:13, 23 June 2019 (UTC)
