Coordinate system and scale #9

yufu-liu commented 1 year ago

Hi! Thanks for this amazing work! I am adapting this algorithm to my VR devices so that I can play with it. However, I encounter an issue that the data from my devices are not similar to the one from dataset. I guess it's because of coordintate system or the scale.

Does the dataset use right-hand coordinate system and meter in scale? (The data shows that controllers' position are silmilar in z-axis rather than y-axis.)

After checking the transformation functions step by step, I found the axes change during transfrom from local to global.

Hi ^^ Could you share what kind of transformations you needed to apply to transform your VR device coordinates into the coordinate system used by AGRoL?
