Hello,
I searched for softwares that provide mesh healing features (under the LGPL
license). OpenFlipper seems to be one.
OpenFlipper's features:
1. They use this data structure called Open/mesh which is essentially a
half-edge data structure.
2. They have remeshing capabilities- based on a remeshing algorithm by
Bosch and Kobbelt (A remeshing approach to multiresolution modeling, 2004),
which takes input as average edge length.
3. Topology control features like flipping/splitting edges and
adding/removing faces
But they do not have features involving errors in meshes like gaps,
overlaps, holes, etc.
And for that i've been reading quite a few papers.
'Polygon Mesh Repairing: An Application Perspective' (Attene et. al) being
a congregation of a lot of them.
For each error (like gaps, overlaps, holes, singular elements-verices,
edges, T-joints, skewed elements) there are certain algorithms that can be
chosen based on the situation. I'm working on it and will come up with a
flow chart of sorts which will take in as input the erroneous BoT and in a
sequence heal each error one by one by a suitable algorithm and pass it on
to the next step. The order will be taken care of in such a way that any
algorithm will introduce only an error that is handled in a later stage.
My query is, whether writing it from scratch will be a boon or bane? Advice
required.
Also, i had submitted a modified patch (#429- surface area of an ARS) with
substantial proof that the patch gives more accurate results. Kindly review
if possible.
I'm looking for a BoT-related patch to work on. I saw the bounding box task
listed, but i tested it on a few objects and it works fine. Is it still
open? If not, is there any other area concerning BoTs that i can work on?
Regards,
Rakshika.
