Did you tried to generating point with normal? #24

I'm just asking this out of curiosity.

Did you tried to generating point with normal? I think it is much easier way to generate meshes by making LION generate point cloud with its normal (N, 6). Then it can build meshes by just applying DPSR directly instead of additionally fine-tuning SAP.

yes I tried that before and it's able to generate reasonably good normal. One thing is that the fine-tuned SAP is more robust to the noise in the sampled points. If the normal is generated, it would still be better to fine-tune the following mesh reconstruction method to adapt to the noise (in points and normal) for better performance.
