[Closed] generate mesh from tracking points
hi there everyone
im searching for a way to generate a mesh from a group of points (helpers) that i imported from a camera track from after effects
i found a few posts about it but no solution , i know programs like PFtrack and others are able to do it , you select the tracking points you want to use and the program generates a mesh from those pints , creating vertices in place of those tracking points .
i understand that creating the verts and giving them the position of the helpers is not the problem , but connecting those verts into a mesh is a different story
so while trying to think of a different way to go about it i thought maybe its possible to create by hand a plane mesh the is the size of the group of points
roughly orient it to the “surface” they represent
then using then maybe shooting a ray from each helper position towards the plane object
either finding the closest vert and moving it to the position of the helper
or refining the mesh at the ray intersection point and moving that vert to the position of the helper
then relaxing all the verts that weren’t used to average the surface to the edited verts
do you think its a good approach ? or is there a better way to go about it ?
i have over 20 shots that i need to bring to max and it seams there must be a better way then generating the mesh by hand
any help and comments would be appreciated !
the first thing that comes to mind is a convex hull made on points cloud…
try
[i]nvpx[/i].[i]CreateConvexFromPoints[/i]
see mxs help for details.
if it works for you there are algorithms to make it more accurate.
hmm… i think that a strategy of consistent connecting nearest points as building edges and faces makes sense. at least you can build not convex meshes this way.
