[Visualpython-users] Camera point of vue

[<fre...@gb...>]

Hello,

I have a question related to the vpython camera usage.

I simulate a photo panohead, where a DSLR is fixed. I would like to=20
simulate the view I have from that DSLR. So, I need to set the vpython=20
camera position, and update the direction it is point at.

But I don't know how to do that. Using the center attribute only sets the=20
point the camera *looks*.

Is there a way to set the camera position, say to (0, 0, 0), and only use=20
the forward attribute to rotate it? A 'from' camera attribute could be=20
usefull...

Thanks,

Study the program "movecamera.py" in the contributed section of 
vpython.org. I think it will answer your question.

I read this example, but I didn't find the answer. I need to *precisely*=20
set the camera position at (0, 0, 0), because this is the point around=20
which my panohead rotates. So, if the camera is not at that position, when=
=20
I rotate the head, there are a parallax errors.

I'm not sure to be very clear....
