129  abstract =     "Clustering is a very efficient technique for applying
130                 finite element methods to the computation of global
131                 illumination of complex scenes. Both computation time
132                 and memory consumption can be reduced dramatically by
133                 grouping the primitives of the input scene into a
134                 hierarchy of clusters and allowing for light exchange
135                 between all levels of this hierarchy. One problem with
136                 clustering methods, however, has been to determine good
137                 bounds on the exchange of light between nodes in the
138                 hierarchy. In this paper, we propose a set of methods
139                 applicable to both clusters and surface patches that
140                 allows for computing conservative but tight error
141                 bounds on the light transport between clusters and
142                 surface patches. Their intrinsic properties can be
143                 exploited by splitting the computation of bounds into a
144                 set of related methods, applicable to any object. The
145                 resulting algorithm abstracts from the nature of the
146                 interacting objects -- light transport between
147                 clusters, planar patches and even curved surfaces can
148                 be efficiently approximated and bound by a single set
149                 of methods.",

162  abstract =     "Although Hierarchical Radiosity was a big step forward
163                 for finite element computations in the context of
164                 global illumination, the algorithm can hardly cope with
165                 scenes of more than medium complexity. The reason is
166                 that Hierarchical Radiosity requires an initial linking
167                 step, comparing all pairs of initial objects in the
168                 scene. These initial objects are then hierarchically
169                 subdivided in order to accurately represent the light
170                 transport between them. Isotropic Clustering, as
171                 introduced by Sillion, in addition creates a hierarchy
172                 above the input objects. Thus, it allows for the
173                 interaction of complete clusters of objects and avoids
174                 the costly initial linking step. In this paper, we
175                 describe our implementation of the isotropic clustering
176                 algorithm and discuss some of the problems that we
177                 encountered. The complexity of the algorithm is
178                 examined and clustering strategies are compared.",

251                 to define a natural {"}flow{"} over the surface of an
252                 object and, as such, can be used to guide the placement
253                 of the lines of a stroke texture that seeks to
254                 represent 3D shape in a perceptually intuitive way. The
255                 driving application for this work is the visualization
256                 of layered isovalue surfaces in volume data, where the
257                 particular identity of an individual surface is not
258                 generally known a priori and observers will typically
259                 wish to view a variety of different level surfaces from
260                 the same distribution, superimposed over underlying
261                 opaque structures. This paper describes how, by
262                 advecting an evenly distributed set of tiny opaque
263                 particles, and the empty space between them, via 3D
264                 line integral convolution through the vector field
265                 defined by the principal directions and principal
266                 curvatures of the level surfaces passing through each
267                 gridpoint of a 3D volume, it is possible to generate a
268                 single scan-converted solid stroke texture that can be
269                 used to illustrate the essential shape information of
270                 any level surface in the data. By redefining the length
271                 of the filter kernel according to the magnitude of the
272                 maximum principal curvature of the level surface at
273                 each point around which the convolution is applied, one
274                 can generate longer strokes over more the highly curved
275                 areas, where the directional information is both most
276                 stable and most relevant, and at the same time downplay
277                 the visual impact of the directional information
278                 indicated by the stroke texture in the flatter regions.
279                 In a voxel-based approach such as this one, stroke
280                 narrowness will be constrained by the resolution of the
281                 volume within which the texture is represented.
282                 However, by adaptively indexing into multiple
283                 pre-computed texture volumes, obtained by advecting
284                 particles of increasing sizes, one may selectively
285                 widen the strokes at any point by a variable amount,
286                 determined at the time of rendering, to reflect shading

773                 reflection is presented. It is based on the calculation
774                 of {\em extended form-factors}, which allows arbitrary
775                 geometries to be used in the scene description, as well
776                 as refraction effects. We also present a new sampling
777                 method for the calculation of form-factors, which is an
778                 alternative to the {\em hemi-cube} technique introduced
779                 by Cohen and Greenberg for radiosity calculations. This
780                 method is particularly well suited to the extended
781                 form-factors calculation. The problem of interactive
782                 display of the picture being created is also addressed
783                 by using hardware-assisted projections and image
784                 composition to recreate a complete specular view of the
785                 scene.",

804                 such solutions to be computed quickly and efficiently.
805                 Firstly, a new technique for bouncing the error in the
806                 transfer of radiosity between surfaces is discussed,
807                 incorporating bounds on form factors, visibility,
808                 irradiance, and reflectance over textured surfaces.
809                 This technique is then applied to the problem of
810                 bounding radiosity transfer between clusters of
811                 surfaces, leading to a fast, practical clustering
812                 algorithm that builds on the previous work of Sillion.
813                 Volumes are used to represent clusters of small
814                 surfaces, but unlike previous algorithms, the
815                 orientations of surfaces inside each cluster are
816                 accounted for in both the error bound and radiosity
817                 transfer. This enables an accurate solution to be

908                 light transport problem, inspired by the Metropolis
909                 sampling method in computational physics. To render an
910                 image, we generate a sequence of light transport paths
911                 by randomly mutating a single current path (e.g. adding
912                 a new vertex to the path). Each mutation is accepted or
913                 rejected with a carefully chosen probability, to ensure
914                 that paths are sampled according to the contribution
915                 they make to the ideal image. We then estimate this
916                 image by sampling many paths, and recording their
917                 locations on the image plane. Our algorithm is
918                 unbiased, handles general geometric and scattering
919                 models, uses little storage, and can be orders of
920                 magnitude more efficient than previous unbiased
921                 approaches. It performs especially well on problems
922                 that are usually considered difficult, e.g. those
923                 involving bright indirect light, small geometric holes,
924                 or glossy surfaces. Furthermore, it is competitive with
925                 previous unbiased algorithms even for relatively simple
926                 scenes. The key advantage of the Metropolis approach is
927                 that the path space is explored locally, by favoring
928                 mutations that make small changes to the current path.
929                 This has several consequences. First, the average cost
930                 per sample is small (typically only one or two rays).
931                 Second, once an important path is found, the nearby
932                 paths are explored as well, thus amortizing the expense
933                 of finding such paths over many samples. Third, the
934                 mutation set is easily extended. By constructing
935                 mutations that preserve certain properties of the path
936                 (e.g. which light source is used) while changing
937                 others, we can exploit various kinds of coherence in
938                 the scene. It is often possible to handle difficult
939                 lighting problems efficiently by designing a
940                 specialized mutation in this way.",

964                 represents a significant improvement of a previously
965                 described approach both with respect to speed, accuracy
966                 and versatility. In the first pass two photon maps are
967                 created by emitting packets of energy (photons) from
968                 the light sources and storing these as they hit
969                 surfaces within the scene. We use one high resolution
970                 caustics photon map to render caustics that are
971                 visualized directly and one low resolution photon map
972                 that is used during the rendering step. The scene is
973                 rendered using a distribution ray tracing algorithm
974                 optimized by using the information in the photon maps.
975                 Shadow photons are used to render shadows more

1263                 integrates volumes and surfaces. In particular no

1300                 analytical models. They also require less expert
1301                 knowledge about the illumination models and their
1302                 parameters. There are a number of hurdles to using
1303                 measured reflectance functions, however. The data sets
1304                 are very large. A reflectance distribution function
1305                 sampled at five degrees angular resolution, arguably
1306                 sparse enough to miss highlights and other high

1644  abstract =     "A number of techniques have been proposed for flying
1645                 through scenes by redisplaying previously rendered or
1646                 digitized views. Techniques have also been proposed for
1647                 interpolating between views by warping input images,
1648                 using depth information or correspondences between
1649                 multiple images. In this paper, we describe a simple
1650                 and robust method for generating new views from
1651                 arbitrary camera positions without depth information or
1652                 feature matching, simply by combining and resampling
1653                 the available images. The key to this technique lies in
1654                 interpreting the input images as 2D slices of a 4D
1655                 function - the light field. This function completely
1656                 characterizes the flow of light through unobstructed
1657                 space in a static scene with fixed illumination. We
1658                 describe a sampled representation for light fields that
1659                 allows for both efficient creation and display of
1660                 inward and outward looking views. We have created light
1661                 fields from large arrays of both rendered and digitized
1662                 images. The latter are acquired using a video camera
1663                 mounted on a computer-controlled gantry. Once a light
1664                 field has been created, new views may be constructed in
1665                 real time by extracting slices in appropriate
1666                 directions. Since the success of the method depends on
1667                 having a high sample rate, we describe a compression
1668                 system that is able to compress the light fields we
1669                 have generated by more than a factor of 100:1 with very
1670                 little loss of fidelity. We also address the issues of
1671                 antialiasing during creation, and resampling during
1672                 slice extraction.",

1721                 unstructured irregular grids with a rendering cost that

1886                 interact only if the error bound is below an acceptable

1939                 been proposed as general methods of representing the
1940                 visual information present in a scene. These methods
1941                 represent this information as a 4D function of light
1942                 over the domain of directed lines. These systems use
1943                 the intersection points of the lines on two planes to
1944                 parameterize the lines in space. This paper explores
1945                 the structure of the two-plane parameterization in
1946                 detail. In particular we analyze the association
1947                 between the geometry of the scene and subsets of the 4D
1948                 data. The answers to these questions are essential to
1949                 understanding the relationship between a lumigraph, and
1950                 the geometry that it attempts to represent. This
1951                 knowledge is potentially important for a variety of
1952                 applications such as extracting shape from lumigraph
1953                 data, and lumigraph compression.",

2200                 penumbral regions has been hard to come by, mainly due
2201                 to the computational expense of determining the visible
2202                 parts of an area light source. Consequently, sampling
2203                 strategies have been mostly ad hoc, and evaluation of
2204                 the resulting approximations has been difficult. In
2205                 this paper, the structure of penumbral irradiance is
2206                 investigated empirically and numerically. This study
2207                 has been made feasible by the use of the discontinuity
2208                 mesh and the backprojection, an efficient data
2209                 structure representing visibility in regions of partial
2210                 occlusion. Regions of penumbrae in which irradiance
2211                 varies nonmonotonically are characterized empirically,
2212                 and numerical tests are performed to determine the
2213                 frequency of their occurrence. This study inspired the
2214                 development of two algorithms for the construction of
2215                 interpolating approximations to irradiance: One
2216                 algorithm reduces the number of edges in the mesh
2217                 defining the interpolant domain, and the other
2218                 algorithm chooses among linear, quadratic, and mixed
2219                 interpolants based on irradiance monotonicity. Results
2220                 from numerical tests and images are presented that

2248                 rapid generation of sequences representing any
2249                 arbitrary path in a ``view space'' within an
2250                 environment in which both the viewer and objects move.
2251                 The global illumination is stored as time sequences of
2252                 range-images at base locations that span the view
2253                 space. We present algorithms for determining locations
2254                 for these base images, and the time steps required to
2255                 adequately capture the effects of object motion. We
2256                 also present algorithms for computing the global
2257                 illumination in the base images that exploit spatial
2258                 and temporal coherence by considering direct and
2259                 indirect illumination separately. We discuss an initial
2260                 implementation using the new framework. Results and
2261                 analysis of our implementation demonstrate the
2262                 effectiveness of the individual phases of the approach;

2309                 Theoretical growth in light transport computation is
2310                 shown to be O ( n + k 3 ) for sufficient refinement,

2314                 experimental trials. Naive application of three point

2335  abstract =     "Given two or more objects of general topology,
2336                 intermediate objects are constructed by a distance
2337                 field metamorphosis. In the presented method the
2338                 interpolation of the distance field is guided by a warp
2339                 function controlled by a set of corresponding anchor
2340                 points. Some rules for defining a smooth
2341                 least-distorting warp function are given. To reduce the
2342                 distortion of the intermediate shapes, the warp
2343                 function is decomposed into a rigid rotational part and
2344                 an elastic part. The distance field interpolation
2345                 method is modified so that the interpolation is done in
2346                 correlation with the warp function. The method provides
2347                 the animator with a technique that can be used to
2348                 create a set of models forming a smooth transition
2349                 between pairs of a given sequence of keyframe models.
2350                 The advantage of the new approach is that it is capable
2351                 of morphing between objects having a different
2352                 topological genus where no correspondence between the
2353                 geometric primitives of the models needs to be
2354                 established. The desired correspondence is defined by
2355                 an animator in terms of a relatively small number of
2356                 anchor points",
