Hello!
I’m working on an architecture project working on a tall church, and am setting up views to render, trying to keep a 2-point perspective. When I set the view top 2-point perspective, it seems to set the horizon line to the centre of the page.
Is there a way to extend the viewing window up or lower the horizon line whilst keeping the verticals vertical? If I move the viewing pane, Rhino shifts the content within the pane.
May well be doing something wrong, any help would be greatly appreciated!
You can move the scene up and down in the viewport and it will keep 2 point perspective. If you want to set the eye line to a particular height go to the viewport properties and set both camera and target z coordinates to the same value.
Note that the eyeline will be level, but the ground plane will appear tilted. If you want to have the higher eyeline but have the ground plane appear flat you need a shifted view. Rhino can’t do that, so your only option would be to have a double height viewport with a lot of foreground that you crop out in an image editor. (Actually, some render engines can render a shifted view - if you’re lucky enough to have one, that’s another solution.)
Given that it is available in render engines (e.g. Maxwell) it can’t be too difficult. But given that it is available therein, maybe McNeel feel that suffices.
@nachetz That’s exactly the sort of view I’m looking for, but every time I go to set the two-point perspective, rhino repositions the horizon line to the centre of the screen, with the camera and target elevations to the same Z value. I’m then unable to “look up” as it were using the walkabout tool to create the view you have.
Any thoughts would be greatly appreciated!
Use this simple model and try moving the mouse up and down in the 2pt view with the right button depressed. Do it with and without shift, to see how pan and rotation can be combined to get what you want. Note the use of a wide lens to exaggerate perspective.
Repositioning in 2-point perspective mode is now working for me. I have been able to orbit and pan in this view all morning now, and have created the views I needed.
I think the issue has been that I’ve been trying to set the views using Walkabout mode, which in true perspective allows the camera to “look up”, but for some reason isn’t allowing the same for 2-point. I’ve been able to create the same setup using orbit and pan, but it would be a useful feature to see in future! (or maybe I’ll come back to Rhino in a week and it’ll have decided it’s going to work again, it might just be me!)
Hi @Jarek,
Thanks so much, this is a really helpful little plugin, shame there isn’t much to be done with adapting the right mouse button but this helps greatly, particularly for the minor adjustments where orbiting can be a bit crude!
Thanks so much, everyone!
Note that this plugin can toggle between regular and TwoPoint perspective without resetting the camera and target to the same level, like the Rhino does. So one can set the view using intuitive RMB-rotations etc. in 3PP and then toggle, and in the end just tweak up/down and zooms using the other commands options from the plugin.
