Hello,

I have a simple conceputal question. In your description of the quantized mesh format, one needs to know the bounding sphere of a tile. After a little research, I realize that algorithms calculating exact bounding spheres are quite complex and demanding.

I found much simpler algorithms but their accuracy is variable. Between 5 and 20% bigger than the optimum. I realize that all that might be resolution dependent, but how accurate do we need to be?

Thank you for your anwsers.

Kind Regards

LG
