Fig. 7.

A vasculature mesh created with the proposed metaballs implementation. The resolution of the metaobject is automatically set to 0.5 to create a highly tessellated mesh in (A). The meshes in (B), (C) and (D) are created with metaobject resolutions of 1.0, 2.0 and 4.0, respectively. These meshes have much fewer polygons than the original mesh in A, but their quality is degrading correspondingly. The small vessels and loops are not reconstructed in C and the large vessels are completely fragmented in D
