Perspective Viewport Properties

[mcolinp]

Am I missing something or is there no way to adjust the Perspective Camera Properties. Most CAD programs have a way to adjust the Lens properties which make more or less skew in relation to say a wide angle lens or a normal say 50mm lens. I find the default perspective to be way to wide angle and blown out. Would like to be able to change this.

Check out the documentation for the class SoPerspectiveCamera
With our python interface you're able to change some settings there. As start point you can use this line:

Code: Select all

from pivy import coin
camera=Gui.ActiveDocument.ActiveView.getCameraNode()
camera.heightAngle.setValue(...)

But make sure that you have switch to perspective mode before.

Hi,
Looks like the option heightAngle is no more accessible. Is there in the meantime something easier to change the viewangle directly in Freecad?

Looks like the option heightAngle is no more accessible.

Works here:
OS: Windows 10
Word size of OS: 64-bit
Word size of FreeCAD: 64-bit
Version: 0.17.10665 (Git)
Build type: Release
Branch: master

Python version: 2.7.8
Qt version: 4.8.7
Coin version: 4.0.0a
OCC version: 7.0.0

Note:
* camera.heightAngle attribute is not listed in autocompleter, you have to type it in manually. This isn't the only place where it happens btw, but attributes of coin nodes are especially well hidden. They don't appear in dir(camera) and camera.__dict__.
* angle is in radians.

THX. All I needed to know !

After all these years does somebody know if there is a GUI for camera properties, __including__ these lens properties? If not, would it be a welcome thing to have? If yes, is there some module/marcro/source code known that comes most close as a starting point? Did someone already dig into such project?

I agree, most of the responses to this feature request are answers about moving the camera, which is not the same as the camera focal length. Being able to set the focal length of the perspective camera is a must have feature for rendering small parts.

Try searching the web for pivy that are python library that expose coin3d methods.

Probably necrobumping after 1 year a post already necrobumped after 3 years or so is not a way to obtain an answer.

Or trying to see what was answered to the feature request.

Please provide me with links to *FreeCad* articles about all kind camera parameters. Position, focal length distortion etc ... I while ago I started working on scripts, but stumbled on not having enough information. Internet is quite slow here (30 Kb/s downto 5 Kb/s) and it is not fun searching that way, so please do the search for me, and I'll restart, ans continue working on a camera GUI.
