I’ve been testing the tool for the past few days trying to find out what it likes and doesn’t like. I have a few questions that maybe some others are coming across as well:
Model scale and orientation: I use Agisoft Photoscan Standard, so I have no way of aligning/scaling my model until the very end (after texture reprojection). With that being said, I use the align function a lot. But sometimes this causes my template model to scale really small and far away from the origin. Does this have any effect on the registration?
Point Placement: I tend to like to place a few points (around 10) to help guide the registration process. How many are too many, does the system like to work with less? Also does the points just initially deform the model to those points, then ignore and slide/relax? Or are the completely matched and locked?
Fitting model, then repeating process: Is there any value added to running the registration process again after the initial mesh has been conformed? Sometimes I think it helps, other times the results are the same.
Ears: The most troubling area I have is the ear geometry (maintaining thickness). Any suggestions? Add additional manual points.
High Poly: Does the topology make any difference? (Decimated triangles versus something more uniform?)
The tool is really great, I just have to do some polishing at the end. I’m sure future iterations will allow us to skip that step all together. Keep up the great work! ;D
1) Model scale and orientation: I use Agisoft Photoscan Standard, so I have no way of aligning/scaling my model until the very end (after texture reprojection).

It seems like this is a bug in QuickAlighnment tool. Yes, the registration is very sensitive to initial alignment. It is always better to have Template and Target well aligned in right-bottom viewport before using Registration tool.
2) Point Placement: I tend to like to place a few points (around 10) to help guide the registration process. How many are too many, does the system like to work with less?

It’s better to use as less as possible. It might tend to irregular mesh if one use too many.
The truth is that we do not have our scanning studio and at the moment we only have few scan examples to play with. Several studios will kindly provide us with more examples that will help us to “finetune” the algorithm for practical needs. It is just a matter of time. Anyone who can provide us with some test data would do a great help for the development process. Off cource all the data will be kept private, we also ok with signing NDA.
3) Fitting model, then repeating process: Is there any value added to running the registration process again after the initial mesh has been conformed? Sometimes I think it helps, other times the results are the same.
That’s a drawback of a current version. If you have bad results you can twick parameters and control points and click “Start registration” again without hitting Done. Sorry about that. That is something to be changed.
4) Ears: The most troubling area I have is the ear geometry (maintaining thickness). Any suggestions? Add additional manual points.
In upcoming version there will be a tool “Select free faces” which will alow to specify faces which you don’t want to be wrapped to target surface. Those free faces will be deformed as rigid as possible just to match remaining mesh deformation. By specifying back side of ear geometry as “free faces” it will be possible to solve the problem
5) High Poly: Does the topology make any difference? (Decimated triangles versus something more uniform?)
It is designed to work with arbitrary mesh topology. But for now Wrap works poorely with big Template meshes. It is only a performance problem. Please wait for upcoming versions.
Thanks for the quick reply, I do have a few questions on the responses:
1) Model scale and orientation: I use Agisoft Photoscan Standard, so I have no way of aligning/scaling my model until the very end (after texture reprojection).

So if the models align in the right-bottom, but are rather small and not axis aligned, is that okay? Does scale and orientation throw anything off?
3) Fitting model, then repeating process: Is there any value added to running the registration process again after the initial mesh has been conformed? Sometimes I think it helps, other times the results are the same.

Is there any benefit if I run the registration process, hit done to apply the effect, then start a new registration with the resulting mesh?

Yay!!! ;D
Also, if we want to submit some models for your internal testing, what would be the best way to do that? Are you looking for high poly meshes and templates?

Before entering Registration mode the models in right-bottom should match each other as good as it possible. By matching i mean a nose goes to a nose, an ear goes to an ear. It does not matter how they are rotated or zoomed in a viewport. Actually rotation, panning and zooming are just a viewport operations, they do not change models. Hope that make sense. Sorry for my english!

I’m not sure if that can be useful

That would be just great! Yes, meshes and templates both would be very useful! I have just sent you an email with my suggestions!
Can we put our meshes in the program for the template? Or we can only work with the template you send in the program?
I need to know this before I buy the program
yes. Wrap ment to be used with customer’s template meshes. It works slow on big template meshes so far, but we are working on performance. Please follow our releases!
