The Software That Makes This HappenĪlthough IBM software has been around for quite a few years, the technology only recently matured enough to be considered production ready. In addition, some video game developers have adopted image-based solutions utilizing these techniques for fast creation of photorealistic backdrops or humanoid models. For example, architecture or archaeology sites where you can evidently immerse your viewers into a virtual 3D world with pinpoint accuracy, or the matching of camera perspectives for overlaying 3D over 2D elements for your compositing needs. There's already quite a growing list of uses for IBM in production environments some of the more evident roles it can play are the exact recreation. Let's take a look at how this technique can assist your projects. Furthermore, more advanced image-based techniques have already made their way into production environments. Although IBM is relatively new, researchers such as the renowned Paul Debevec and artist Greg Downing have made very impressive discoveries utilizing image-based techniques. By using a typical consumer digital camera to take these photographs, it makes this technique accessible to a very wide range of users. IBM is the process of having the user take photographs from different points of view and then using these photographs as a "starting point" in the process of using point-to-point measuring tools in an image-based modeling application. © replace_caption_photogrammetry02.gif Understanding Image-Based Modeling Tour this 3D environment created with ImageModeler. I will attempt to help those who dont understand exactly what IBM is, and explore its pros and cons. With the ability of artists to explore objects and scenes captured from real world photography, it has become extremely attractive, but it does carry its share of limitations, which we will explore later in this article.Īlthough image-based techniques cover a wide range of topics, including animation, inverse lighting, light field rendering, layered depth images, to name a few, I will cover the process of creating 3D models from normal everyday photography. With the advent of image-based modeling (IBM), the technique has caused quite a stir in the industry and rightfully so. Plus it may not always be beneficial to spend extensive time creating complex models such as humans, cars or any other real-world subjects in a day-to-day production pipeline. If you have the Quicktime plugin, you can view clips of photorealistic models by simply clicking the image.Īlthough advancements in recent modeling techniques have advanced by leaps and bounds, the process of creating photorealistic models remains a somewhat tedious and time-consuming task depending on the circumstance and whom you ask.
