Hi there,
Some times in production, we receive a facial expressions 3d scans . but the model is split into 3 parts, front, left, right. Each expression comes in 3 obj files and their corresponding textures. this is great because there is more detail in the scan but pain to work with. I was wondering if there is an easy solution to combined the scans into one and then use the wrap node.
Hi,
I’m assuming that you are using some structured light scanner and scan a face from 3 different angles.
First, you need to align them, a standard algorithm for that is ICP alignment. You can use [b]Meshlab /b or Geomagic Studio to do that. We are also going to add this algorithm in Wrap soon.
Second, you need to merge 3 scans into a single mesh (welding overlapping parts). That also can be done in Meshlab or Geomagic.
Third, you need to combine multiple textures into a single texture which I’m not really sure how to do. Technically you can reproject textures from each piece onto the merged mesh producing 3 textures in the same UV space. Then you can combine them using masks. There should be a better solution though.
Hope that helps!
I want to know if there are people still playing the forums again.
