Image-based rendering (IBR), techniques that generate new images from other images rather than geometric primitives, appeared to burst onto the computer graphics scene in the last few years. This panel of pioneering IBR researchers defined IBR and placed this emerging technology in a continuum of developments, then speculated on the long-term impact of IBR on computer graphics by addressing issues such as: What is IBR good for? Will IBR replace polygons? What could IBR mean for graphics on the Internet? What are the implications of IBR for hardware design?
