Remeshing for Model Targets

July 19, 2022 - 5:01pm #1

For model targets, is it okay if a provided mesh has some intersecting faces, degenerate geometry, etc.? If not, is this something that Vuforia's mesh simplification process would take care of in addition to the simplification? Finally, do the answers to the previous questions change if the mesh is, despite self-intersecting and whatnot, still watertight?

I want to make sure I'm getting the best tracking performance possible out of my model targets, but I also do not want to unnecessarily waste time trying to improve the meshes I need to work with (manually remeshing them is not feasible given their level of detail, and I'm still searching for a good tool that would do it automatically).

Hello,

We've seen issues in the past with meshes that had duplicated surfaces that were intersecting each other. In particular, if those surfaces had different colors and the intersections introduced artificial edges that were not existing in reality. In this case, simplification also didn't help.

Our base position is that we do not support this kind of model. But, of course, there is nothing to stop you from trying it to see if it works.

Good luck!

Kind regards,

Hi Dave,

Thank you for your reply. I read through those pages before, and while they mention how the model shouldn't have holes, my model is already watertight and these pages do not discuss intersections or degenerate geometry (as far as I can tell). Does the fact that they're not discussed mean that they wouldn't be a problem?

Hello,

Please review these articles for optimizing Model Targets for the best tracking performance:
