Re: [Bf-committers] [GSoC2011] Mesh Retopology Tool Enhancements Including Step-Building, Extending, Slicing, Enhanced Pen and Paint Tools
Dear all, I have updated my proposal for your review. http://dl.dropbox.com/u/14061228/gsoc_blender_retopology.pdf Updates include BMesh considerations and a rethought and clarified list of tool proposals. Also includes slice based shrunk cylinder creation http://www.3d-coat.com/uploads/pics/rtp_slices.gif Includes two optional (time permitting) semi automated tools for very fast artist determined (ie not fully automatic) quad generation.

Dear all, I have further amended my proposal to give focus to new tools rather than existing tools. I have also added detail and description to tool specifications. http://dl.dropbox.com/u/14061228/gsoc_blender_retopology.pdf Best wishes, Dan On 6 April 2011 11:33, Dan Walters wrote: > Dear all, > > I have updated my proposal for your review. > > http://dl.dropbox.com/u/14061228/gsoc_blender_retopology.pdf > > Updates include BMesh considerations and a rethought and clarified > list of tool proposals. > > Also includes slice based shrunk cylinder creation > http://www.3d-coat.com/uploads/pics/rtp_slices.gif > > Includes two optional (time permitting) semi automated tools for very > fast artist determined (ie not fully automatic) quad generation. > > Best wishes, > > Dan > > On 4 April 2011 19:28, Tom M wrote: >> Discussed this with Dan a bit, while he clearly put a lot of thought >> into the proposal, it looks like he based some assumptions that we >> were still using the system that Nick did for retopo in 2.43 using the >> depth buffer, etc. (Note that this was a reasonable assumption - >> small version number changes people assume == minor changes *cough*) >> >> http://www.blender.org/development/release-logs/blender-243/retopo/ >> >> However retopology work flow has changed quite a bit, current tools >> are now the surface snapping during transforms; the shrinkwrap >> modifier; and the surface sketching addon - the depth based method is >> no longer available. >> >> Most of his tool proposals would also involve adding tools to our >> current mesh system which is due to be replaced with BMesh.

Hi Sergey, Thank you for the information. > But I will rebuild last year quad based automatic remeshing code by > Rohith with most fresh Blender code ( or even with Bmesh ) - so it > will be seen if that code could be used as aid tool for you. This could be a huge help, thank you very much. As I understand there was a lack of availability of suitable libraries that stopped the GSoC project from going further? > The nice feature of that code - that > after you have feature lines ( with your proposed tools ) are rendered > - then automatically generated mesh will keep those > feature lines intact ( and also will preserve borders ) - so new > retopo mesh will easily fit into bigger mesh and retopo of large > pieces of mesh ( not only retopo with 4 or so quads per selected > 'section') will be also easy and intuitive with your tool. yes, i can see how this could be useful if moving back and forth between z-brush etc. > Bmesh, of cause ( with more flexible structures ) , will be of help here too. I am anticipating this! As I understand, it is an easier library to work with and provides more utility functions than the existing mesh library. > So if your proposal is accepted, I will make you aware of new builds > and you would be able to access if that code could fit into your > proposal as underlying 'quad-generation' code over selected feature > lines ( taking into account the mesh, of cause ). That would be very useful, I'd be really interested to see how well the last years GSoC project on auto-retopo worked, if it could be adapted for use in any way that would be awesome. Thank you for the feedback, Best regards, Dan ___ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers

Discussed this with Dan a bit, while he clearly put a lot of thought into the proposal, it looks like he based some assumptions that we were still using the system that Nick did for retopo in 2.43 using the depth buffer, etc. (Note that this was a reasonable assumption - small version number changes people assume == minor changes *cough*) http://www.blender.org/development/release-logs/blender-243/retopo/ However retopology work flow has changed quite a bit, current tools are now the surface snapping during transforms; the shrinkwrap modifier; and the surface sketching addon - the depth based method is no longer available. Most of his tool proposals would also involve adding tools to our current mesh system which is due to be replaced with BMesh. So I'm not sure if this should instead be reworked to be applicable to bmesh. Or suggest he focus on the retopo tools that were suggested on the page which are not nearly as dependent on the underlying mesh code.
