Camera models can then be designed for specific applications and optimized dynamically for each 3-D scene or dataset to achieve adequate sampling. Another consideration in camera model design is preserving image computation efficiency in order to support interactive rendering of dynamic scenes.+    * //**Thesis: Improved 3-D Scene Sampling by [[http://wiki.cs.purdue.edu/cgvlab/doku.php?id=projects:camera_model_design|Camera Model Design]]**// – In order to create images that better sample 3-D scenes, I propose abandoning the constraints of the conventional planar pinhole camera model by no longer requiring that rays be straight, converge, or sample space uniformly. Camera models can then be designed for specific applications and optimized dynamically for each 3-D scene or dataset so as to achieve adequate sampling. At the same time, camera models should also be designed to preserve image computation efficiency in order to support interactive rendering of dynamic scenes.

==== Camera Model Design ==== ==== Camera Model Design ====
-Camera model design is a novel paradigm for computer graphics, visualization, and computer vision that advocates designing the camera model to best suit a given application and optimizing it dynamically according to the data currently sampled. Like conventional images, the resulting images have a single layer, they are continuous and non-redundant, and they can be computed efficiently with the help of graphics hardware. Unlike conventional images, images produced by camera model design have a variable sampling rate and integrate seamlessly multiple or even a continuum of viewpoints [1, 2, 5, 6, 9, 11]. +Camera model design is a novel paradigm for computer graphics, visualization, and computer vision that advocates designing the camera model to best suit a given application and optimizing it dynamically according to the data currently sampled.

-There are many aspects of human perception that have not been studied with respect to stimuli which are not naturally occurring, non-pinhole camera stimuli for instance. The lack of previous exposure to these types of stimuli may in some cases make it difficult for humans to perceive correctly without training. For example, we completed a study using 3-D volumetric displays where the volume appears transparent to the viewer, a phenomenon not normally seen in nature [8, 10]. Another example is our forthcoming study which will show how effectively humans can perceive some non-pinhole stimuli.+

-This interdisciplinary project, between civil engineers and computer scientists, focuses on modeling, simulating, and visualizing extremely large scale systems. We built an automatic, general-purpose, and scalable tool linking the worlds of finite element simulation and animation. To demonstrate this tool, we produced a simulation and science-based animations of the September 11th attack on the World Trade Center North Tower. The associated press release was the most widely covered in Purdue University history with the video appearing on most of the major news networks. Video clips have also appeared in History, Discovery, and National Geographic Channel specials related to the attacks. Finally, the video will appear in the National September 11 Memorial and Museum in the new World Trade Center tower. To date, the video has been downloaded over 7 million times [3]. +This interdisciplinary project, between civil engineers and computer scientists, focuses on modeling, simulating, and visualizing extremely large scale systems.

-There has been a recent push towards the convergence of graphics hardware with general purpose hardware, as indicated by the popularity of CUDA, OpenCL, and the excitement related to Intel’s forthcoming Larrabee architecture. This convergence of high-performance hardware opens up the potential for new problem solving approaches. Some examples of this include the development of an efficient software-based pipeline with the potential, for example, to directly render non-pinhole camera models [7, 15, 16, 17]. Another example of work in this field involves geometric computing with advanced graphics hardware support with the goal of solving high-order equations efficiently [12, 13, 14].+There has been a recent push towards the convergence of graphics hardware with general purpose hardware, as indicated by the popularity of CUDA, OpenCL, and the excitement related to Intel’s forthcoming Larrabee architecture.
