Hi all,<br>
<br>
I'm curious what people think about switching the default camera lens<br>
from "plane-parallel" to "perspective".<br>
<br>
Perspective cameras are more intuitive - it makes sense to talk about a<br>
camera position and orientation, since all the rays originate from a<br>
single point.<br>
<br>
The last time this came up, the major concern was that perspective<br>
renders were not as performant as plane-parallel renders.<br>
<br>
Today Kacper submitted a PR that substantially improves the performance<br>
of the perspective camera:<br>

<br>
If we benchmark and find that the plane-parallel camera is competitive<br>
with the plane-parallel camera in terms of speed, would it be ok to<br>
switch to perspective for the default camera?<br>
