model sharpening tools?

[roger johnson]

Can anyone suggest tools or software that tries to sharpen the surface of a 3d model which has been created using photogrammetry or by scanner..

You can import an .obj file in Blender (freeware). There are several tools, by exemple "sculpture" in order to soften/modify the surface, an edit mode... This is a complex software and you need some time and practice. But it is very efficient.

Thanks i will look into it

but it sounds like I need something that creates edges that have perhaps have been worn away with erosion

Hi Roger,
Using "Edit Mode" in Blender you can add vertex (points) and edges, modify their places and so on. Generaly 3DF creates and huge number of points and triangles. When we modelise in Blender we try to minimise the number of vertex (low poly). In a first step try do reduce the number of points in 3DF before exporting: Tools>Mesh Filter>decimation (with the copy option) and export in .obj mode.

roger johnson Something you could experiment with is the Edge Filter slider when creating a mesh or applying a Photoconsistency Based Mesh Optimisation to your model

thanks to you both..

I've still a lot of catching up todo

but hopefully will be back in due course

I had a quick try and loaded one of the rosetta stone 3d models using load model option

Unfortunately the option for photoconsistancy is greyed out so it doesnt look like I can use the edge filter....

unless I have the original source photos
