Dolly to cursor reaches limit about camera-controls

[yomotsu]

Would you mind providing a simplified working example on CodeSandbox or a similar platform to reproduce the problem?

FYI: you must set minDistance to not a small value if you wish to enable infinityDolly

Hi @yomotsu ,

I'm working with @sguimmara. I reproduced this issue with an example derived from the infinity-dolly example: https://codepen.io/tmuguet/pen/poBXyyd .
In this example, if you try to dolly-in in the top-left or top-right corner, you end up getting stuck, whether infinite dolly is enabled or not actually.

Thank you for providing the demo.

I believe the minDistance value is too small relative to the scene's scale.
For instance, a value of 100 is nearly insignificant when considering camera positions such as camera.position.set(59861, -543453, 600000) and other similar settings.

Could you try using a larger number for the minDistance value?

Thanks for your prompt answer!

Setting a larger number (like 10000) fixes this issue, but it comes with some side-effects:

• when we get close to the plane (i.e. our map), the value is obviously too large, so we easily traverse the plane we're targeting (that's why minDistance was initially set to such a low value),
• when we hit that value, setOrbitPoint (which we bind on right-click) makes the camera jump.

We've tried using setBoundary to bound the target, but it also introduces some other side-effects.

I believe there's no "one value fits all uses-cases". I'll try to have an adaptative minDistance then.
