Previous approaches broke the geometry image into multiple rectangular or irregular charts to reduce distortion, but complicated the automatic level of detail one gets from MIP-maps of the geometry image.<\/jats:p>\n          <jats:p>We introduce triangular-chart geometry images and show this new approach better supports the GPU-side representation and display of skinned dynamic meshes, with support for feature preservation, bounding volumes, and view-dependent level of detail. Triangular charts pack efficiently, simplify the elimination of T-junctions, arise naturally from an edge-collapse simplification base mesh, and layout more flexibly to allow their edges to follow curvilinear mesh features. To support the construction and application of triangular-chart geometry images, this article introduces a new spectral clustering method for feature detection, and new methods for incorporating skinning weights and skinned bounding boxes into the representation. This results in a tenfold improvement in fidelity when compared to quad-chart geometry images.<\/jats:p>","DOI":"10.1145\/1731047.1731049","type":"journal-article","created":{"date-parts":[[2010,5,6]],"date-time":"2010-05-06T17:41:18Z","timestamp":1273167678000},"page":"1-13","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":14,"title":["Feature-preserving triangular geometry images for level-of-detail representation of static and skinned meshes"],"prefix":"10.1145","volume":"29","author":[{"given":"Wei-Wen","family":"Feng","sequence":"first","affiliation":[{"name":"University of Illinois at Urbana-Champaign, Urbana, IL"}]},{"given":"Byung-Uck","family":"Kim","sequence":"additional","affiliation":[{"name":"University of Illinois at Urbana-Champaign, Urbana, IL"}]},{"given":"Yizhou","family":"Yu","sequence":"additional","affiliation":[{"name":"University of Illinois at Urbana-Champaign, Urbana, IL"}]},{"given":"Liang","family":"Peng","sequence":"additional","affiliation":[{"name":"Intel Inc., Santa clara, CA"}]},{"given":"John","family":"Hart","sequence":"additional","affiliation":[{"name":"University of Illinois at Urbana-Champaign, Urbana, IL"}]}],"member":"320","published-online":{"date-parts":[[2010,4,21]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1145\/1073204.1073276"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1145\/508357.508360"},{"volume-title":"Proceedings of the Eurographics\/SIGGRAPH Symposium on Geometry Processing. 181--190","author":"Carr N.","key":"e_1_2_1_3_1","unstructured":"Carr , N. , Hoberock , J. , Crane , K. , and Hart , J . 2006.
