文摘
- •
An efficient approach to generating hierarchical multi-resolution MA of a CAD model is proposed.
- •
The affected region and the re-voxelization region are proposed to reuse voxels when the MA level is upgraded.
- •
An adaptive double queue distance dilation based algorithm is proposed to refine MA automatically.
- •
The MA quality metric is proposed to evaluate the MA.
