[gts-general] Re: GTS do something about view-depend lod

[Haifeng Li <pos...@gm...>]

Hi Adrien=20
Thanks for your suggestions, and i will refere the archive.
I noticed that gts include some class as following:

Surface simplification and refinement -- reducing or increasing the
number of edges of a triangulated surface.

Out-of-core simplification -- objects for simplification based on
vertex clustering

Vertex split -- object encoding a reversible edge-collapse operation.=20

Progressive surfaces -- continuous level-of-detail for surfaces.=20

Hierarchical vertex split -- hierarchical extension of the vertex split.=20

Hierarchical surfaces -- extension of progressive surfaces allowing
arbitrary sequences of vertex split or collapse.

All of them had relationships with the LOD. So which one should i use?
By the way,  what you did impressed me, could you send a demo about
your work or something more details to me? Thank you.

Kindly Regards

Haifeng
