Projectors for graphics.
SIGGRAPH '08: Special Interest Group on Computer Graphics and Interactive Techniques Conference Los Angeles California August, 2008(2008)
摘要
Modern digital projectors are a central part of large-format displays, non-intrusive augmented reality systems and computational illumination for 3D image-based modeling. High speed and high framerate projectors also support intriguing applications in optical communication. With a pocketsize form factor, projectors will be widely used for mobile applications. We survey this rapidly evolving landscape and the growing interest in experimenting with projectors. A novel class of applications is emerging, involving illumination+capture of complex 3D shapes as well as dynamic interaction via projection on movable surfaces. We provide a detailed survey of the several approaches for combining real-time computer graphics and computer vision methods for single and multi-projector systems. We cover topics in immersive rendering, projective geometry, reflectance field capture and spatial augmented reality. In addition, we will give practical insights, implementation details and case-studies for a variety of applications in research, art and industry.
