[Bf-committers] [GSoC2011] Mesh Retopology Tool Enhancements Including Step-Building, Extending, Slicing, Enhanced Pen and Paint Tools

[Dan Walters]

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

Includes two optional (time permitting) semi automated tools for very
fast artist determined (ie not fully automatic) quad generation.

Best wishes,

Dan
