Question: Y axis upside down #93

Open xiasun opened 3 months ago

xiasun commented 3 months ago

Hi all,

I have customized splat data with the y-axis pointing upwards (ground at y zero). However, when rendered with gsplat.js, it appears upside down. I have to set the splat's rotation around the x-axis to 180 degrees to make it display correctly.

After going through the entire project, I couldn't find any default behavior that would cause this upside-down rendering. I'm wondering if gsplat.js performs any preprocessing on the loaded data. If not, why is my data being displayed upside down?

Many thanks!

It depends on the coordinate system used for the source model. It would be a good feature to load splats with an axis conversion though!
