---|
| 427 | general computer graphics we need to consider large |
---|
| 428 | numbers of objects in order to render one image. In |
---|
| 429 | many cases rendering can be preceded by a culling phase |
---|
| 430 | which employs simple mechanisms to reject most of the |
---|
| 431 | objects. As a result, only a very small portion of the |
---|
| 432 | model has to go through the time consuming process of |
---|
| 433 | hidden object removal. We report on such a culling |
---|
| 434 | mechanism that is based on regular space subdivision |
---|
| 435 | into cells followed by cell classification into |
---|
| 436 | interior, exterior, and wall cells. A special |
---|
| 437 | cell-to-cell visibility algorithm is then activated |
---|
| 438 | between every two non-exterior cells. Only the objects |
---|
| 439 | in the potentially visible set of cells are actually |
---|
| 440 | submitted to the hidden object removal algorithm. We |
---|
| 441 | report on the implementation of the algorithm and its |
---|
| 442 | performance for walkthrough of various environments.", |

| 919 | space occlusion maps. Occlusion maps represent the |

---|
| 1076 | globally illuminated scenes has to date proven an |
---|
| 1077 | elusive goal. Previous attempts have failed to provide |
---|
| 1078 | interactive updates of global illumination and have not |
---|
| 1079 | been able to offer well-adapted algorithms controlling |
---|
| 1080 | the frame rate. The need for such interactive updates |
---|
| 1081 | of global illumination is becoming increasingly |
---|
| 1082 | important as the field of application of radiosity |
---|
| 1083 | algorithms widens. To address this need, we present a |
---|
| 1084 | novel algorithm which provides interactive update rates |
---|
| 1085 | of global illumination for complex scenes with moving |
---|
| 1086 | objects. In the context of clustering for hierarchical |
---|
| 1087 | radiosity, we introduce the idea of an implicit |
---|
| 1088 | line-space hierarchy. This hierarchy is realized by |
---|
| 1089 | augmenting the links between hierarchical elements |
---|
| 1090 | (clusters or surfaces) with shafts, representing the |
---|
| 1091 | set of lines passing through the two linked elements. |
---|
| 1092 | We show how line-space traversal allows rapid |
---|
| 1093 | identification of modified links, and simultaneous |
---|
| 1094 | cleanup of subdivision no longer required after a |
---|
| 1095 | geometry move. The traversal of line-space also limits |
---|
| 1096 | the amount of work required to update and solve the new |
---|
| 1097 | hierarchical system after a move, by identifying the |
---|
| 1098 | modified paths in the scene hierarchy. The |
---|
| 1099 | implementation of our new algorithm allows interactive |
---|
| 1100 | updates of illumination after object motion for scenes |
---|
| 1101 | containing several thousand polygons, including global |
---|
| 1102 | illumination effects. Finally, the line-space hierarchy |
---|
| 1103 | traversal provides a natural control mechanism allowing |
---|
| 1104 | the regulation of the tradeoff between image quality |

| 1260 | for a frequently changing viewpoint or view vector is |

| 1263 | this paper to meet this demand in a very efficient |
---|
| 1264 | manner. A pre-processing phase, in which a feudal |
---|
| 1265 | priority tree is established for all polygons of an |
---|
| 1266 | object, and a post-processing phase, in which a |
---|
| 1267 | rendering priority list is searched for from the feudal |
---|
| 1268 | priority tree for a new viewpoint or view vector, are |
---|
| 1269 | included in our approach. The most time-consuming work |
---|
| 1270 | is finished in the pre-processing phase which only has |
---|
| 1271 | to be executed once for an object, and the relatively |
---|
| 1272 | simple task is left to the post-processing phase, which |
---|
| 1273 | is repeated when the viewpoint or view vector is |
---|
| 1274 | changed. For the pre-processing phase, a static version |
---|
| 1275 | and a dynamic version are proposed in this paper. The |

| 1276 | one-way priority relations of all polygons are computed |
---|

| 1278 | more efficient way than that in the static |

| 1279 | pre-processing, but the latter part of the dynamic |
---|
| 1280 | pre-processing is still based on the static |
---|
| 1281 | pre-processing. A new concept of ``absolute priority'' |

---|
| 1283 | which a separating plane is to be searched for so the |

| 1284 | probability of finding the separating plane is much |

| 1285 | increased. This is the basis to implement another |

---|
| 1513 | expensive in storage or computation. The Visibility |
---|
| 1514 | Skeleton is a new powerful utility which can |

---|
| 1516 | for the entire scene. The Visibility Skeleton is a |

| 1517 | multi-purpose tool, which can solve numerous different |
---|
| 1518 | problems. A simple construction algorithm is presented |
---|
| 1519 | which only requires the use of well known computer |
---|
| 1520 | graphics algorithmic components such as ray-casting and |
---|
| 1521 | line/plane intersections. We provide an exhaustive |

| 1522 | catalogue of visual events which completely encode all |
---|
| 1523 | possible visibility changes of a polygonal scene into a |
---|
| 1524 | graph structure. The nodes of the graph are extremal |

| 1525 | stabbing lines, and the arcs are critical line swaths. |

| 1527 | Visibility Skeleton for scenes of over a thousand |
---|
| 1528 | polygons. We also show its use to compute exact visible |
