AJAX Platform for Image Based Rendering in Cloud Computing

We have developed a software platform that enables users to view real-world objects interactively using AJAX technology. Our rendering technique is image-based — the virtual 3D views of an object are synthesized by interpolating 2D images, leveraging the high-quality of recent digital photographs. This approach alleviates the difficulty of modeling 3D geometry in existing approaches to 3D computer graphics. The software can run on various kinds of devices using web browser without additional software installation, which makes it possible for users to experience photo-realistic 3D computer graphics in cloud computing environment.

Demos

Note: Google Chrome browser is recommended to run the following demos for better performance.

This page shows a proof-of-concept of light field rendering in a web browser. You can drag the image to change the viewpoint interactively. The viewpoint is limited to 1D circular paths or a 2D planes where the input images are acquired. The software is implemented using simple HTML elements so that it runs on any standard web-browser without additional softwares such as flash or other browser extensions.

This page is the full version of out lightfield renderer. The virtual 3D views are generated using a set of unstructure images. You can drag mouse to freely change the viewpoint and look around in 3D space. You may have to use modern web-browsers that are capable of HTML5.0 and optimized for Javascript.

One of the interesting aspects of light field rendering is dynamic re-parameterization of synthetic aparture. In this demo, you can see the person behind bushes by blurring out the partial occluder.

Light field video can also be rendered interactively in a web browser using our technique. Each frame of the video is synthesized independently by sequentially downloading a large number of images. Warning: Running this demo may use up your network bandwidth.
