Creating a virtual tour with panoramas from beginning to end
Generally, you can always just try things out with the program – There is nothing that you can do wrong so feel free to play around with effects and tools. With our preview tool you can see right away the changes that you made and whether you like them or not.
Step 1: Take photos of the place you want to show in your virtual tour. Unlike other software suppliers, 3DVista also allows you to create virtual tours with just partial panoramas, which means you will not have to take photos of the whole 360° scenery but you can also have a tour that covers a smaller angle.
There are a couple of things that you should remember when taking the photos
- You can use any camera and any lens for taking the photos. Nonetheless, there is some equipment that facilitates the process. Click here for more info or watch our video tutorial on "What equipment do I need to make a panorama".
- Especially when using fisheye or wide angle lenses you have to use a tripod with a panohead mounted on top.
- The individual photos should overlap by approximately 20%, which means that those photos that are next to each other in the panorama need to overlap by 20%. This overlap area is necessary, because it is where the program finds common control points between the two photos, which are used to stitch them. This is where the panohead comes into play because it will only let you rotate the camera up to the optimum point, making sure that you always maintain the right distance between the photos.
- With a point and shoot camera or cell phone: Place your camera in portrait or vertical mode (in order to have a wider vertical field of view), keep your arms close to your body and start spinning clockwise around your own axis while you take several pictures. Again, it is important that the individual photos will have an area of overlap of approximately 20%.
- With a DSLR camera and tripod: If you’re using a tripod, things will get a lot easier, quicker and more accurate. Set up the tripod with attached camera in the best viewing spot (usually the middle of the room). Use the bubble indicators on your tripod to ensure that your camera is level from front to back and side to side. Set the camera in portrait position and start taking several photos by rotating the head of the tripod. Remember to maintain a 20% overlap between shots.
- With a DSLR camera, a tripod and a panohead: Set up the tripod in the best viewing spot (usually the middle of the room). Mound the panohead on top of the tripod and attach the camera to the panohead making sure that the end of the lens is vertically right above the rotation axis. It is absolutely crucial that the lens of the camera and not the body be right on top of the rotation axis to avoid changes in perspective when rotating the panohead. Rotate the panohead right until you feel it click into place and take a photo. For a full panorama take one final photo of the ceiling and optionally a photo of the floor (without the tripod).
Once you have the pictures taken, the process of creating the panoramas and the virtual tour starts. To learn how this is done, please take a look to our Quick Guide, where we describe this process in detail. LINK TO QUICK GUIDE
