These architectures define not only his company, but provide the high-performance 3D graphics facilities that cnablc scientists, cnginccrs. animators. and other users to visualize. crcatc, and dream in new ways. Kurt Akclcy received a B.E.E. Prom the University of Dclawarc in 19X0. and an M .S.E.E. from Stanford in 19X2. That year hc was a mcmhcr. with previous Achicvcmcnt Awn&c Jim Clark. of the lounding team ol‘ Silicon Graphics. lncorporatcd. Ilc has hecn a key technical contributor since then wtth primary dcsipn rcsponsibillty for most of the high-end graphics architccturcs in SGI’s product history. Kurt dcvclopcd the rramc burfcrs and proccssol subsystems lor the early INS series products. and many of’ the CAD tools used to design thcsc and other products. Ilc was instrumental in dcvcloplng the graphics systems for the Power Series and Onyx systems. including the GTX. the VGX. and the Rcalltyl~n~inc. Ilc also led the dcsipn and documentation of the OpcnGI. graphics software specification. which is now supported by Silicon Graphics and many other workstation and personal computer vendors. Clearly he is a hardwarc wizard. hut one who also has a deep understanding of software and cspccially the critical interaction bctwecn hardware and softwarc.

{"title":"A realistic camera model for computer graphics","authors":"Craig E. Kolb, D. P. Mitchell, P. Hanrahan","doi":"10.1145/218380.218463","DOIUrl":"https://doi.org/10.1145/218380.218463","url":null,"abstract":"Most recent rendering research has concentrated on two subproblems: modeling the reflection of light from materials, and calculating the direct and indirect illumination from light sources and other surfaces. Another key component of a rendering system is the camera model. Unfortunately, current camera models are not geometrically or radiometrically correct and thus are not sufficient for synthesizing images from physically-based rendering programs. In this paper we describe a physically-based camera model for computer graphics. More precisely, a physically-based camera model accurately computes the irradiance on the film given the incoming radiance from the scene. In our model a camera is described as a lens system and film backplane. The lens system consists of a sequence of simple lens elements, stops and apertures. The camera simulation module computes the irradiance on the backplane from the scene radiances using distributed ray tracing. This is accomplished by a detailed simulation of the geometry of ray paths through the lens system, and by sampling the lens system such that the radiometry is computed accurately and efficiently. Because even the most complicated lenses have a relatively small number of elements, the simulation only increases the total rendering time slightly.
