Zoom In/Out

I'm trying to zoom in/out of a 3D room. At the moment, I've
replicated this using a translate function:
if gZoomIn then pCamera.translate(0,0,-1) --gZoomIn refers to
the mousedown of a different sprite
But I don't want to move the whole camera. Is the
'FieldOfView' the best function to use? I can set this to a
specific angle (like 90 below) but I can't seem to increment this
by +/-1 on a mousedown
if gZoomIn then pCamera.fieldofview =90
Any ideas on how to script this?

Yes, the 'zoom' feature of real-life cameras is the
equivalent of the field of view of director 3d camera objects.
Physically moving the camera forwards and backwards towards the
target is actually called 'dollying' in real life.
To narrow the field of view by one degree per frame, you
could use something like this:
if gZoomIn then pCamera.fieldofview =pCamera.fieldofview - 1
You'll want to limit it to a minimum though, which can easily
be achieved by using the 'max' command:
if gZoomIn then pCamera.fieldofview
=max(30,pCamera.fieldofview - 1)
The above line will zoom in, but keep the field of view from
going lower than 30 degrees. The matching 'zoom out' would look
like this:
if gZoomOut then pCamera.fieldofview
=min(120,pCamera.fieldofview + 1)
hope this helps!

Adobe illustrator CC Zoom in & out problem

Hi,
I am facing an issue right now..
When i open a large AI file that above 1GB, then i zoom in & out .. the design will go out of form.
However, when i open small file like 400+ MB, no issue on zoom in & out.
I really no idea for this issue..
Here is my PC spec,
Windows 8.1 Professional
3.40 gigahertz Intel Core i7
32GB RAM
NVIDIA GeForce GTX 650
TQ.

Alt & scroll wheel not working on Photoshop CC to zoom in / out

Hey! So i'm using the latest version of Photoshop CC, and i'm also running the Technical Preview of Windows 10. So In Photshop, usually when you hold the alt key and scroll with the scroll wheel on your mouse, it will zoom in / out of the image on Photoshop. Well i'm having some problems with that, it isn't working at all. In preferences I have it set to zoom with scroll wheel. Anyone know why it isn't working? Could it be something with the Windows 10 Preview?

Please report Windows 10 issues to Microsoft, so they can get the information they need to fix the OS bugs before shipping the final version.

Sound like a trackpad problem and not an iPhoto one. Have you asked in the forum dedicated to the Mac model you're using or is this an add on trackpad?

Sometimes when panning with the hand tool, it zooms way out instead of just moving the canvas

So normally when you hold the space key and drag, it just moves the canvas, but every now and then, seemingly randomly, it zooms way out and shows a little box which is the size and shape of the area of canvas I was previously looking at. If I move the box and let go of space, it zooms to that location, but all I wanted was to move normally. I don't think I've ever wanted the zoom out, move, then zoom back in behavior. What causes that? How do I make it stop?

It's "bird's eye view" and by coincidence, your problem was discussed in another thread last night: Problem with zoom in Photoshop CS6

I am unable to zoom in/out using the touch pad; yesterday i could zoom in/out of website pages, pics, etc, now today it is not letting me; how do i fix this?

T510: TouchPad no longer allowing for zoom in/out

My TouchPad is all the sudden no longer allowing for zoom in/out. How do I restore that function.
Moderator Note: Edited subject to match content.

My T520 has recently developed a similar problem.
With no obvious warning it now seems unable to recognise the trackpad/point. I've tried various combinations of uninstalling/installing drivers etc with no success.
When clicking on the mouse tab in Control Panel an error message says: Unable to connect to the Synaptics Pointing Device. It then suggests removing the synaptics driver and then reinstalling other mouse drivers. This doesn't make sense as I don't have any other mouse drivers installed (bar the in-built Win7 ones which can't be removed anyway). Then rebooting the system results in no pointing devices being available at all. The trackpad gets recognised as a PS2-compliant device and prompts installation of drivers (from synaptic) which just gets back to square one.
Also, the control panel mouse tab won't show the ultranav utility even though that is installed properly.
So, I'm having to use an external mouse as the system doesn't seem to be able to properly use the trackpad/point. I'll keep troubleshooting but suspect this may be a software/driver issue as it was working perfectly up until recently and the hardware can still "see" the device. Both are enabled in BIOS.
Any other people experienced similar problems?

ScrollPane zoom in/out

Hello, this is my first post.
I'd like to add zoom in/out function to my ScrollPane, and make shortcut (CTRL+MOUSE SCROLL UP/DOWN) for it. ( like Inkscape )
I made the following code ( Canvas ) to achieve this, but have some problems.
*1. How can I prevent ScrollBar's thumb to move when pressing CTRL?*
When ScrollBar is visible and ScrollBar's thumb (or scroller, knob) has room to move, CTRL+MOUSE SCROLL UP/DOWN doesn't work because the thumb moves instead of zooming in/out.
When the thumb moves up/down to bar's end, then zoom in/out finally works fine.
*2. ScrollEvent handler is sometimes not called in ScrollPane*
When ScrollBarPolicy is not ScrollBarPolicy.ALWAYS and Scrollbar is not visible, SOMETIMES CTRL+SCROLL UP/DOWN operation dosen't work.
(ScrollEvent handler is not called. For other panes, ScrollEvent works fine. Please check MouseScrollEventTest below)
Thank you in advance.

Thank you for the good example.
But actually, I just give up using ScrollPane and created a ZoomCanvas which can zoom in/out and pan.
The code is here.
Any comments or improvement would be appreciated.

Browsers auto zoom in/out

Hello,
Recently my browsers (safari,chrome) behave oddly, it auto zoom in/out, sometimes really fast like it shaking or something, so far it only happens when i'm using Wacom tablet, I don't know exactly when this started, I guess when I upgraded to 10.6.6, i've asked Wacom Support they suggested to re-install driver, but still problem persist. Maybe anyone here knows what's going on?

Must be a setting on the tablet. You need to speak to Wacom.

Zoom in-out and rotation in trackpad

Zoom in-out and rotation in trackpad doesn't work in iPhoto, Aperture, Preview, Finder. Any solution?
It works perfect at safari

What context in the Finder would you expect zoom to work? same question for rotate?
I am able to see rotate and zoom working in iPhoto and Preview. I do not have Aperture so I cannot check.

OBI HD App No zoom in/out option

Hi Experts,
I have got Oracle BI HD App on my ipad2 and its pointing to OBIEE 11.1.1.6.8 version and Zoom in/out is not avialable in it. I can see the dashboards as i see on any web browser.
Earlier when i pointed Oracle BI HD App to OBIEE 11.1.1.5.0 , zoom in/out option was avaiable and I need not have to scroll out horizontally(verticall scroll is fine).
please provide inputs if there is any configuration required for OBIEE 11.1.1.6.8 version Zoom in/out so that whole dashboard tab fits into my ipad screen and zoom in/out can be used.
Cheers
