Error-limited Mesh decimation #40

Open TheBlune opened 7 years ago

TheBlune commented 7 years ago

Hi @alecjacobson

thanks for the great work and your help so far.

I need to decimate meshes until a certain error-treshhold is reached. The meshes have a high precision and I cannot afford to lose too much details. Is there anything in your Toolbox that could help me with that?

As I understand your proposed point_mesh_squared_distance(P,V,F)-Function (Point, Vertices, Faces?) computes the distance to the nearest point...I need to compare the original mesh with a decimated mesh or something similar.

Common High-precision Data defines the error as max. distance of mesh patches to original surface or min distance of two vertices to be allowed to create a Patch between them.

Thanks in advance.

Best regards TheBlune

Maybe also have a look at: https://github.com/bldeng/GuidedDenoising http://www.danielgm.net/cc/

Thanks for your help. Unfortunately I wasn't able to open the second link and the "supplementary Material" Link on the Github-Page of bldeng and therefore didn't find any evidence of an error-parameter or error-algorithm I could use.
