If it is similar in performance (serial and parallel), 1) well done! 2) definitely in favor of switching Cheers, Sam On Mon, Mar 7, 2016, 8:29 PM Cameron Hummels wrote:

I believe the perspective camera is the most intuitive, and if the speed is similar to the plane-parallel lens as suggested, I am all for switching the defaults. But it may mean we need to tweak some of the cookbook recipes because many of them were made with the plane parallel lens in mind.

I think that it makes sense to make perspective the default -- that's what most other vis packages seem to default to.

Hi all,

I'm curious what people think about switching the default camera lens from "plane-parallel" to "perspective".

Perspective cameras are more intuitive - it makes sense to talk about a camera position and orientation, since all the rays originate from a single point.

The last time this came up, the major concern was that perspective renders were not as performant as plane-parallel renders.

Today Kacper submitted a PR that substantially improves the performance of the perspective camera:

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

Ditto here; it is more aligned with peoples' expectations about volume rendering (and also easier for us to make 3D renderings if we want to!) On Tue, Mar 8, 2016 at 8:23 AM, John Wise wrote:
