The most spectacular presentation of a panorama is most certainly the 360° virtual tour. To create it correctly, you'll have to follow a certain number of steps, not necessarily essential, but when they're all followed carefully, the quality and easiness of stitching is here. Unless you choose a 360° camera like the Ricoh Theta SC or Insta360 One X because it is the current Google Streetview trend that makes dream realtors .. without offering them a very good quality, still early 2020, despite the efforts of manufacturers! Here are all my advices to help you choose..
A virtual tour, possibly on 360°x180°, is a particular case in panoramic photography by stitching. It is a recent way to show panoramas in an interactive way, hence necessarily online, which participated in the digital revolution of this field of photography, by the way. When you're watching a 360° virtual tour, it is thus possible to interact with the panorama using your mouse by rotating it in all directions, from the floor to the ceiling in some cases, to go from one room to another, to zoom in the image, to read information, to watch videos, etc.
Shaun t workout videos. In all the pages of this tutorial in the The guide to panoramic photography, dedicated to this particular field that is the realization of virtual tours, I'll try to explain you how to proceed and what makes it so singular. As you can guess, it is quite technical when you want to do things right, but it also became a lot easier from 2011 on..
Want to create a virtual tour but not sure how? This video will take you through every step of creating a virtual tour. WHAT YOU'LL NEED: 360 Camera Ricoh T. Oct 18, 2019 First important point: have fun, because you can create virtual tours with almost any camera with changeable lenses. The ideal is to be able to mount a fisheye lens because the shooting of a complete sphere will be noticeably quicker. Then, it's better to have 20 Megapixels because then, with eight photos only, you can realize a quality virtual. Virtual webcam is typically a software only implementation that application discover as if it is a device with physical representation. The mentioned applications use APIs to work with web cameras and ability to extend the APIs and add your own video source is the way to create a virtual web camera.

G says if schools have the secure, virtual platforms for live classroom learning, students should turn their cameras on so teachers and other students can see them.
Key points if you're a beginner.. On top of each page, I'll indicate the essential points that should draw your attention if you're a beginner. The rest of the page is aimed at those who want to learn more. To sum up, we can already say that it will be about shooting a whole sphere on 180° x 360°. For this you can directly use a 360° camera like the Ricoh Theta SC or the Insta360 One X. The procedure is very simple but the picture quality really not great for the moment (Early 2019). The Google Streetview program is happy however. It is true that their use is very simple. If you want a better quality then you need a camera that accepts fisheyes lenses. These 'special' lenses that shoot 180 degrees by deforming the image as in the eye of a fish, allow you to shoot a sphere in only a few photos (between 4 and 8 maximum). Another advantage, working with fisheye lenses, it will cost you a lot less - starting from $200 - because the 'classic' objectives are very large angles and are very expensive and you have to take with them at least fifteen photos and not eight or even less. Use a spherical panoramic head like the so cool Nodal Ninja 3 or 6. Next key points: How many photos do you need? |

Basic principles of a 360° virtual tour
It is only about shooting several photos, most of the time with a very wide-angle lens or even a fisheye, slightly overlapping in order to Stitch them with a dedicated panorama software unless you use a dedicated device like the Ricoh Theta SC or another of its 360° cameras that take care of everything (but at the expense of quality even at early 2020). But unlike more classic panoramic photography by stitching, you'll need a panoramic head of a spherical type because it is about, if you have big ambitions, shooting a whole scene from the floor to the ceiling.. Of course, the tripod won't be visible in the final 360° virtual tour! The best ratio considering the number of photos, the quality and the quickness of realization is eight photos with a recent 20 Megapixels body nowadays. Still in 2019, the best ratio of photos / quality / speed is five / eight photos today with a recent box of 20 Mpixels but it's still too long for some applications (especially for Google Street photographers or agents real estate) and the Ricoh Theta SC to mention that allows him to realize a complete panorama in a single shoot if we accept a definition and a final quality much less !!!
Before / After in images
We'll take the eight photos below, shot with a fisheye full-format lens, as a starting point and observe their journey and transformations..
Once Stitchd by an stitching software like Autopano Giga, the photos are rendered in a spherical geometric projection below typical. Straight lines curl ..
Here is typically a photo shot on 180°x360° rendered in spherical mode: the top and the bottom of the panorama are completely distorted. But once mounted as a virtual tour - in six cube faces as you can see below, and where you can notice that the floor side returns to its normal aspect - and watched online, everything gets back to normal because this photo is redistorted automatically.
Important note! The typical distortion of this 360° photo above is absolutely not due to the fact that the photos were taken with a fisheye but only because a 360° photo is necessarily Stitchd in a so-called spherical projection that rounded also necessarily all the straight lines. This photo would have the same look if it had been taken in 21 photos with a wide angle 'classic' of 24 mm. She would have just more pixels. The fisheye lens just lets you work faster.
Those six cube sides are automatically distorted to be watched in an online page;

We on the OBS team thank CatxFish for their hard work on this plugin.
This plugin provides a directshow Output as a virtual webcam .
How to use:
Output:
1. Selecting Tools -> VirtualCam
2. Press start button and close diailog
3. Open your 3rd party program and choose 'OBS-Camera' as a Video input
Filter:
1.Add a filter to the source you want to output to the camera
2.Choose a sink camera target then press start button
3.If this camera is not occupied , the start button will change to stop button .
4.Open your 3rd party program and choose 'OBS-Camera' as a Video input.
How to Install without installer:
1.Go Github Release to find zip file
2.Unzip OBS-VirtualCam2.0.1.zip and put it to your obs-studio install folder
3.Run CMD as Administrator and register 32bit directshow source
ex: regsvr32 'C:Program Files (x86)obs-studiobin32bitobs-virtualsource.dll'
4.Do it again to register 64bit directshow source
ex: regsvr32 'C:Program Files (x86)obs-studiobin64bitobs-virtualsource.dll'
Register failed during installation
It's usually due to dependency reason . There's a chance you need to install visual studio 2017 redistributable package (2013 if the plugin version is 1.x.x ), also the directshow interface needs swscale-4.dll and avutil-55.dll in you obs install directory.
FAQ:
Is it necessary to install 32bit version?
Yes, there are still many 3rd party programs use 32bit directshow interface for the reason of compatibility.
Why resolution and framerate are not same as OBS output Setting?
If you open OBS and Start Virtual Output before using your 3rd party software, the virtual webcam will set the obs setting as a default setting .Otherwise the default setting of virtual webcam will be 1920x1080 @ 30fps
Is it possible to output with portrait resolution (like 1080x1920) ?
It depends on your 3rd party software , it might reject recommended resolution.
If your software is compatible , you just need to set the obs output setting to the resolution you want.
How to prevent the drop frame issue?
Maybe your PC is too busy ,try to set more buffer.
Is there a virtual microphone ?
This plugin provide a directshow audio source which can't be recognized as microphone , only some programs like VLC can use it.
Does this plugin support other platforms?
There's a Video4Linux version . But it only contains the sink part , you have to use it with v4l2loopback.
And there's no plan on mac version.
Is the driver-layer virtual device ( for microphone) development still going?
No, there are two reasons why I decide to make it pending.
1. The development is mess and painful, an error could cause blue screen.
2. Even you finish the code , you still need a paid certificate called EV code signing to distribute your driver.
Known issues
- Skype UWP edition don't accept directshow interface , please use Skype desktop edition.
- Unity Application can't get image from virtualcam , please useregister batch(reg_path.reg) in release page to manually add dummy device path .(note: The registry conflict with skype desktop , you can use unreg_path.reg to remove it)
