welcome back i haven't actually got to attempt any implementation yet since some production work required more attention but just using neighboring polys/verts seemed like it would be too slow. since the api provides getting neighbors based on level of connectivity i wouldn't know how many levels of neighbors to access without testing the distance of all the components. that just seemed wasteful. so my intuition was too use point locators with this call... 'GetClosestLocationsWithinRadius'.
i will attempt both versions. thanks for your feedback. s On Mon, Sep 3, 2012 at 3:52 AM, Brent McPherson < brent.mcpher...@autodesk.com> wrote: > Hi Steven, > > Sorry, for the late reply as I was on holidays. > > As far as painting goes you don't really need any special lookups to find > vertices within the brush radius. > > Once you know the current polygon under the brush center (which you got > from the the pick buffer/raycast etc.) you just need to traverse > neighbouring polys/verts (using the mesh topology) until you exceed the > brush radius. > -- > Brent > > From: softimage-boun...@listproc.autodesk.com [mailto: > softimage-boun...@listproc.autodesk.com] On Behalf Of Steven Caron > Sent: 15 August 2012 19:09 > To: softimage@listproc.autodesk.com > Subject: Re: SDK : caching the tool context pick buffer > > hey brent > > GAP related question... are you guys internally using your nearest > neighbor/point locator to get points within the brush radius? say for > weight painting? > > s > On Wed, Aug 1, 2012 at 11:06 AM, Steven Caron <car...@gmail.com<mailto: > car...@gmail.com>> wrote: > cheers! > > s > > On Wed, Aug 1, 2012 at 10:26 AM, Brent McPherson < > brent.mcpher...@autodesk.com<mailto:brent.mcpher...@autodesk.com>> wrote: > The pickbuffer doesn't have the information but intenally we could look it > up on the mesh more efficiently than you can using either the geometry > accessor or polygon arrays in the SDK.
