This is my first BabylonJS project and I’m stuck on understanding rotations of a sphere. Also, this is my first 3D project ever so I can’t say I’m very good at this.
I’m working on a pool/snooker game developed in 2d with PixiJS (so there’s a fixed camera) and now I want 3D animated balls just like Miniclip’s 8 Ball Pool. Miniclip is using spritesheets to simulate 3D rotation.
I came to the conclusion that integrating BabylonJS will solve this request and it almost did excepting the balls rotations which will have to be solved manually, since the spheres will follow the 2D balls coordinates, X and Y (Z is fixed on zero). Just like here:
I found this tutorial and it works excellent in Unity, exactly what I needed, but it doesn’t work in my project.
I think the problem is where the quaternion needs to be multiplied with a vector, I’m not sure.
Also tried this with no result.
Can someone please help me with this?
I created something similar here, based on the mouse coordinates. The earth should rotate while the mouse is move, but of course it doesn’t.
PS: I did search and investigated a lot of topics and solutions but none worked or maybe it’s beyond my capacity of understanding quaternions and math.
