Trouble with Rotate 3d models

Helo, I am start learning ARCore with UrhoSharp.
Now i try rotate model by users click on display.

It is my method`s when i try rotate models. But it work not correctly. Can you help me?

Sorry, I know I could help you, but apparently, it’s bad form to help people here, if they are using the urho sharp fork. Maybe I can answer your question on their forum.
This forum is devoted to Urho3D public and master forks. Nothing else.

Could, you send me link for UrhoSharp Forum?

not totally sure since i choose not to use c#, but
https://developer.xamarin.com/api/root/Urho/
might get you somewhere

I’m just trying to keep things (relatively) on-topic and prevent this community from being suffocated through support of a dead fork. Sure, it’s important to be nice, but a line must be drawn somewhere. If UrhoSharp users get better help here - and it’s hard not to - I do believe these forums may be overrun. To me it seems wiser, for everyone, if UrhoSharp users were to switch to either Urho3D or rbfx instead. Support for rbfx - likewise - should not be expected here.

I believe the closest you’ll get to something you could call the UrhoSharp forums is here:
