About Virtual Reality Object Movie
1. The Principles of VR Object Movie
Virtual Reality Object Movie is an application of image-based virtual reality derived from VR technologies. Conventional photography results in a static image from a single perspective, or a linear dynamic image. The viewer plays a purely passive role when looking at the object, as they can only see it from the angle that is chosen by the photographer. Object imaging however takes pictures of an object at a fixed distance from multiple perspectives at even intervals. These are then recombined into a virtual 3D image of the object using computer software. The viewer can then use a mouse to freely turn and rotate this 3D object image, observing its external appearance in its entirely.
How Object Imaging Works
2. Characteristics of VR Object Movie íV Presenting the Object in a Realistic, Natural and Interactive Manner
The creation of interactive 3D object images are usually divided into Virtual 3D modeling and Object Imaging according to the method used.
Virtual 3D Modeling uses 3D modeling software or 3D scanning equipment to create a virtual model of the object which is then finished using software-based rendering and lighting techniques. The greatest advantage of this approach is the high level of creative freedom, as it allows the shapes, colors and materials to be modified or simulated. It can also be used to set up highly interactive virtual environments with multiple objects or used in conjunction with real imagery, giving it a variety of applications in post-production. The production process however is complex and time consuming, requiring extremely specialized software, hardware and staff all of which lead to high production costs. Though it can achieve a high level of realism in some situations, its effect in large-scale modeling leaves a lot to be desired. The modeling process also involves a large amount of human creative input, so it is still not the same as real images.
Object Movie takes pictures of a real object from multiple angles before combining them into a 3D image using software. Its main feature is that it creates a real image of the object by taking pictures of the actual object itself, making it very suitable for applications such as documentation or online displays of actual objects.The production process involves just the photography and image alignment software.Compared to the software and hardware needed for making virtual 3D models, it is a relatively cheap and simple process.The entire process can be carried out by the photographer working alone, with a trained operator capable of completing dozens of object imaging projects every day.The completed graphical source file can be exported using the image alignment software into a variety of application formats, and then used for web multimedia content.The use of natural optical photography means that the completed project is not easy to create from scratch or tamper with as the content and quality of the imagery was already determined at the time of shooting.There is little room for post-production or retouching as one object image may involve dozens or even thousands of closely related images.Any change to the imagery will require a large number of images to be processed to achieve the same result.This is a task far more complex and prone to error than simply shooting the images.If necessary however the project can still be integrated into panoramas or virtual models.
3. Production Process
1.Adjust the object photographic shelf, background, lighting, camera and object to be photographed.
2.The object and camera are centered.
3.Set up the shooting model and then capture the image from each angle in order.
4.Organize the source graphic files.
5.Enter graphic files into image alignment software for processing.
6.Configure, export, done.
Object Imaging file organization example íV 12 shots 360 degree horizontally * 3 shots at 60 degrees vertically, with 30 degrees difference in visual angle between each shot
