Definitely I am interested in the parts of your pipeline that you find hard to do in meshmixer.
I am not only going to work on mixing meshes. Right now I am working on many aspects of dynamic mesh editing. Definitely I will do additional brushing and sculpting tools. These are things I will integrate from some of my other projects:
- clone brush tool from this video: http://www.youtube.com/watch?v=sJqkS6ucZ0I
- procedural extrusions, creases, etc from this project of mine: http://www.dgp.toronto.edu/~rms/pubs/SurfaceTreeEG08.html
I am also going to do displacement stamping from images, hopefully for mm05.
I already have quite a bit of additional brush things implemented, but they are not solid yet, IE they don't undo properly, are unstable, etc. So I will be releasing those as they become robust.
There are other aspects of mesh editing that I think will be useful to have in meshmixer, ie tools for stitching meshes together via brushing, a "healing brush" that repairs bad mesh areas, remeshing, extrusion, etc. These will come as I do them.
For texturing I am going to do a new kind of UV-layout tool, where you work mainly on the 3D surface. Once I have a way to add UVs, or load them in properly, then I can implement some texture painting tools. And definitely I am going to support drag-and-drop of textured parts.
At some point I am going to add some of my decal textures work from this video: http://vimeo.com/2139401?ab
These will be live texture patches, that you would then rasterize down into a UV layout.
Some of the above will also be useful for doing quad-layout / re-topologizing. This is something I definitely will work on in the coming months.
So, that is a brief overview. Basically I am working on three fronts:
1) easy-to-use tools for 3D novices, people wanting to do 3D printing, etc
2) artist-oriented tools for making detailed meshes and fitting in to production pipelines
3) mesh cleanup and repair tools for everyone who has to deal with meshes (especially scan meshes)
Maybe it is crazy to try to combine these things, but I think it will also be pretty cool...
