HLODs:
Hierarchical Simplifications for Faster Display of Massive Geometric Environments

Images

Figure 3: The Power Plant, a model consisting of 12,731,154 faces and 1,477 objects. The original model is on the left. LODs of the model are shown in the middle consisting of 2,515 faces. A more solid HLOD approximation consisting of 2,379 faces is shown on the right.

Figure 4: The Double Eagle tanker, a model consisting of 126,630 objects and 82,361,612 triangles. The original model is on the left. The right two images are LODs consisting of 7,887 and 1,922 faces.

Figure 5: HLODs of the Double Eagle. The original model is on the left. The right two images are HLODs consisting of 7,710 and 1,914 faces. Notice how HLODs give a more solid approximation of the model.

Figure 6: LODs of the Ford Bronco model. They consist of 74,308 faces (the original model), 1,357 faces, 341 faces, and 108 faces.

Figure 7: HLODs of the Ford Bronco model. They consist of 74,308 faces, 1,357 faces, 338 faces, and 80 faces.

Figure 8: A demonstration of how HLODs generated with partitioning approximate view-dependent simplification.
